As you may have noticed, I have not spent any time on the wikipedia mDict conversions, since I'm very busy with Rawstudio. A very friendly user called "Or" has converted the lastest wikipedia dumps. Here is his message:---Thanks for sharing the source code. An update, based on your work, for October 2010 version is available in: http://ahuv.net/wikipediaLinks to torrents:English: 3,483,000 items

I have recently done quite a lot of assembler for Rawstudio, and when I found out that GCC also has support for SSE intrinsics, I finally set out to learn how to use them.I had done quite a lot of inline assembler using GCC's AT&T syntax, and it works ok, though the syntax is pretty horrible. It also has some serious input restrictions, with only 5 general purpose registers available, when you do

I have spent quite a lot of my spare time in the last two months creating a file loader for RAW files. My primary motivation, beside general interest was, that I was frustrated there wasn't any fast open source loaders out there.So my main objectives were to make a very fast loader that worked for 75% of the cameras out there, and was able to decode a RAW file at close to the optimal speed.

I'm still having some fun playing with my wikipedia parser I posted below. The main reason why I think this kind of exercise is fun is because of the immense amount of data it contains.I took the time, and implemented the first two points on my "possible improvements" list below. I knew that a database would be the logical next step, so I fired up my MySQL, and implemented a simple first pass,

My first "real" language I programmed in was Java, back in the 1.0 to 1.2 days. I've since spent a lot of time with C++ and similar languages, but I sometimes revisit Java, when I feel I have a task that would be better suited for a lighter language.I've recently gotten a new Windows Mobile phone, and I've previously written about development for it. This time, my personal challenge wasn't

I was browsing around my sources, and found a fairly ok working version of RawEngine, I wrote about when I started this blog.The last thing I did was beginning a rather big restructure, which I didn't finish. But I found an older version that seems to work ok. So I thought I'd post a binary and the source files, since I don't plan on continuing using this codebase anyway. Actually it's a big

I have spent some time on my new project, a sound output plugin for AviSynth. It was actually one of many projects, but I wanted to do something new, so a GUI-based AviSynth filter seemed like a good challenge.I had recently touched "traditional" windows GUI, when developing for Windows CE, but it has been years since I last had done some real GUI work (which honestly was mostly copy+adapt+paste)

I have been spending most of the last month and a half on programming for Windows CE at work. It's been a great experience, and I've learned a lot in the last months. The challenge was a graphical presentation client built from the ground up, to replace a Flash 6 based presentation system.PlatformOur main platform was from the start a Pocket PC running Windows Mobile CE5, so the first

I have been searching for a command line Flash 8 (VP6) FLV video creation tool for a long time. I've bought On2's Flix Pro - but even though it is a mile better than Sorenson's horrible Squeeze, it still had some serious issues with AviSynth input for instance. In general it was good for one-at-the time encoding, but batch processing was tedious and buggy.So for a while I had actually went back

(From the Photo Blog)Today I saw an article on HDR images taken in Tokyo, along with some techniques that could be used for creating them. As I'm always interested in new ways of developing photos, I downloaded the Photomantix Software and installed it, and followed some simple instructions [1] [2].For test material I used the Auto Exposure Bracket on my 20D and took three shots of the same scene

(From my photo blog)Today, my girlfriend and myself continued to play with her new macro lense. I got my Centon MR40 Ring flash out, I bought half a year ago for about $35. It's an old type TTL-lense, which doesn't really work to well on my 20D. It fires alright, but it fires at the lowest level, so it didn't really help.My first solution was to set an exposure time at about half a second, and

I have been spending a lot of time on my photo- and personal blog, så I haven't quite kept up with updating my projects page. I have however spent a lot of time on some old, and some new projects.I'll write a bit about status of the larger ones. But my main projects have beenAviSynth 2.6.

To celebrate that Blogger have (finally) made an easy may of uploading pictures, I'm now starting a Photo Blog. The Blog will contain the photos I take, and have taken. Head over to:http://kpgallery.blogspot.com. I'll begin uploading a few shots shortly.Take care! I'll keep on enjoying the good weather here in Denmark.

I've been a bit away again. Mostly at work, but I finally got some time to make some progress. I've been focusing on colorspace aspects, as I noticed differences in output from RAW programs and my own engine. I experimented quite a bit, using various gamma corrections and applying a variety of colorspace transformation matrices.I've almost settled on the steps each image should be able to go

I finally found a little time this weekend for my little project. Not much, but I got around trying to fix some of the bugs I've discovered. Mainly the skew function is giving me headaches. I noticed that the old implementation caused distortions along the triangle edge.The image is drawn using two triangles. When I moved one of the corners it resulted in artifacts along the edge. My first idea

There hasn't been much time for new features lately. I've spent a lot of time on work, photography and more personal stuff. So for now the only update is correct (I hope) White Balance. The white balance is now loaded from the RAW file and automatically being applied to the photo.Right now the only problem I haven't dealt with is the combination of rotation and skew, which currently has problems.

Hi!Now I'm back again, and have resumed work on the Raw Engine. The two lastest features are Levels and Perspective Correction.Levels was quite interesting, as gamma doesn't really make much sense in under- or over-exposed areas. That resulted in some funky colors and weird banding on values less than black and more than white. If I min/max'ed the values before applying gamma, it resulted in

I'll be taking a break from my computer for the next week and go skiing for a week with my family. So for the next week there isn't going to be much development done. Hopefully I'll be able to cook up some great ideas while I'm a bit away from my computer.

I just got annoyed by the default DirectX icon, so I dug up a nice image by Keith Wilson at Stock Exchange. After a little work in PS this is the result:The icon for the application in the different sizes.As for work on the application, I'm doing some cleanup and error handling today. The next task will probably be cropping and after that file saving - most likely using libpng.

So now I got color adjustments done. Brightness, Contrast, Hue and Saturation.Hue and saturation is done in YUV colorspace, since the RGB->YUV->RGB calculation is a lot faster than RGB->HSV->RGB and the result is the same.Brightness is a bit interesting, since it's dealing with unclamped values. That means that when brightness is -100%, overexposed areas will still show through. This is one of

I've been working a bit more on the UI, for now this has been done: File Drag 'n' Drop support. Image rotation, with live update.Automatic Image Rotation based on EXIF. Black Level adjustment. Mouse Wheel support for PS-inspired zoom steps. Minor tweaks and adjustments. I've been fighting for some of these features, since I don't have access to any internet at home, some simple things

I've been working on implementing nice navigation, and so far it looks very good IMHO. Fluid scaling and panning has been put in so far. Easy and intuitive navigation is essential, so that'll be a major part of this application beside speed and high image quality.Last night, I got simple bilinear Bayer interpolation done in hardware. Now the full-size RAW loads in about a second. I also got basic

Just a minor update on things. I managed to get hold of a GeForce FX 5200. It's slow, but it does the job. I managed to upload the data as three 16bit Luminace planes, and use a pixel shader to combine the three images. Here is the result:For some reason I've been imagining that Colors weren't recorded as RGB on my camera, but that makes the task a bit simpler. My next plan is implementing

Even though the tests I did when trying to utilize 3D hardware for video processing were pretty promising, I got an idea for a new and interesting way of using it. For processing RAW footage fra digital cameras. This is a far more obvious usage of modern 3D hardware, and it seems to be a lot better than current software implementations.So I used the last weekend to throw together something that

The last few months I've spent some of my spare time with photography. I've started out slowly by borrowing my girlfriends camera to try out if photography was really something for me. Last weekend I finally pulled myself together and bought myself a very nice camera.I really like getting into these things again. It's been more than 10 years, since I last did any serious photography, but it's

This is as much a personal wishlist, of things I knew I could do if I found the time somehow. Some are more wishful than others. Have a better look at MvTools. Perhaps finetune some stuff like soft block appliance, border motion vector overrides. Get something working in DspSynth. Just saw Digital Fusion. Wow! Thats a great UI and application in general. Don't get your hopes up, though. ;)

Even though it has been rather hard to find some free time lately, I've actually begun getting some actual code done for my new project, which at the moment is called DSPsynth (but that might change again). One of the reasons it has taken me so long to get started is that I've spent some time "upgrading" my C++ skills to avoid making too many silly mistakes in my first implementation attempts.

Just found this very good article on Gamasutra regarding content creation tools. It relates specifically to exporting 3D-material from 3D-packages, but it presents some very good generic guidelines for software creation. Some of the points I noticed: Your software should never "fail". Always provide good informative, and at best visual feedback of the problems. Don't assume artists (and

Just finished Chapterhouse: Dune yesterday night. A very open ending to the Dune Series - I still don't quite know what to think of it. It seems right, that Herbert had something planned, but never got it done before he passed away. So now, I've begun reading Ender's Game. Actually this is a bit backwards since I "accidentally" started by reading Children of the Mind - the last book in the

After finishing Doom3, I've begun looking a bit at the engine. I was a bit surpised at how similar it was to the Quake Engine, and to be honest I had expected more development here. Of course changing the engine more radical would also mean that all previous licencees of the engine would have to re-learn things. Thus, by keeping the basics the same, the Quake to Doom3 transition will be much

Doom 3 It seems like ID software has done it once again; released a mindblowing game. I had the luck to get to play a few hours of Doom 3 at my friends place. The best word for it is "scary". It even surpasses one of my favorite games System Shock 2. The graphics are great. It plays well on my Geforce 4 Ti4200, at lowest resolution. The shadows and general usage of light is the best I've seen

Just got online, after returning from Scene Event 2004. It was great seeing my old buddies, I've had the pleasure of knowing for so long. I also enjoyed the extremely good entries in the demo competition. Great work by all of you! It is funny to see the scene change over time. Especially since I'm no longer that active. However seeing the "return of the demoscene" in recent years is a
