2013-03-20 21:17:24 -0600 | asked a question | Identifying and tracking hands in a scene I am trying to write a HandTracker application to identify and track human hands in a scene. I have tried a number of techniques, which I will detail here. I need your help to figure out the technique or combination of techniques I should use to be successful. What I have:
What I have tried:
After working on this for a week, I'm starting to get more than a little frustrated. I just want to do something simple like the hand tracking in OpenNI. Unfortunately, the OpenNI 1.5 code is so obfuscated that I can't even find the hand tracking portion. Does anyone have any ideas for how I can combine and/or refine these techniques on the color stream or incorporate the depth stream to achieve robust hand identification/tracking? |

2013-03-13 21:34:27 -0600 | asked a question | cvtColor(): Bayer conversion scrambled pixels (channels?) I am new to OpenCV. I am trying to convert a cv::Mat of Bayer data to BGR. The input data is a 640*480 array of uint8_t. My code looks like this: BONUS QUESTION: Does the Mat constructor make a deep copy of the input data? But video_image looks like this: I have tried CV_8UC3 and setting raw.step to 640*3. What am I missing? PS: I took a screenshot because the highgui save image button had no apparent effect on the filesystem. |
