This is basic software that takes information from the camera and analyzes the colors in the picture for patterns that might be people. This will usually only detect the skin. Sometimes, it will get false positives from wood. I am working on that. When you start the program, a black cursor will move across the screen. Green squares will appear where a person test comes out positive. Red squares indicate a possible positive. Then, Green arrows will appear in the rows and columns where it detects a person. Works best when downloaded.
This was jointly developed with theoblongtriangle. Being a novice, his program only involves looking for certain colors. I experimented with several different clarifying filters before I came up with the finished product. Again, for maximum quality results, download the program.
