The screenshot above is my latest little project, a windows based tool for the decomposition of image using my fast pulse transform (FPT) technique. It needed to have a few features like file IO, pulse selections and highlighting of pulses. I’ve never done any sort of c++ winapi programming before apart from some windows forms stuff … Continue reading
Thanks to haDoan for noticing that i had left out the definition for the pixel struct in the source code. When i put up the code, i ripped it out of my surveillance project and didnt noticed the definition was located in a different file. I’ve updated the source code to include the struct definition : … Continue reading
I finally finished the private contract I was doing on saturday, and so I sat down sunday morning to start generating results for the presentation I am going to be doing for the CSIR regarding this on thursday. Things went well until about 2 minutes in when the program crashed, running it from within VS, it dies with an … Continue reading
okay here’s the code and the pseudocode of the DPT implementation, any comments on style, performance and so on are more than welcome… It’s been a few weeks of work to get this done, the algorithm has changed significantly since i first received, from speed optimizations to the removal of redundant code, merging of function … Continue reading
OH MY GOD! its finally done! You have no idea how happy i am right now… (and pretty drained) I’ve spent the last three days debugging the conversion i did from matlab to c++. The problem was that the program would complete but the image wouldnt have been totally cleared (ie. be a fixed value … Continue reading
Okay, its been a really busy week, i’ve been working on the DPT stuff during the day and my evenings have been working on the design doc for our game mod. I’ve completed a rough version of the dpt program but there are still some issues with it, i think the problem is with the … Continue reading
I don’t know if I mentioned this before but my father is a math’s professor at the University of Pretoria. I’ll be doing my honors year next year, and I can maybe get credit for my one subject by helping my dad develop an algorithm/program to do discrete pulse transform in a 2d space. The … Continue reading
Wow, it’s been a rough couple of weeks: I had to hand in my graphics project, study for a statistics test, fighting off my allergies (I hate spring) and then I had to study for my finals. At least I have my degree now. Finally! Anyways, I promised I’d write about the radon transformation I used … Continue reading
Okay, it’s been a while since the last update. I coded the outline extractor as I discussed in my previous post. It works for small objects but once most of the screen or lots of little objects occur it crashes. I think its a memory allocation problem related to my use of STL vectors. Anyways … Continue reading
I’m currently busy working on a feature extractor for my final year project. I’m doing an outdoor surveillance system with shape classification. Currently I’m using a sigma delta background estimation algorithm (removes areas of constant motion from being picked up) to create a background and variance frame and then using those two frames and a … Continue reading
