Individual project for CSE190a at UCSD Winter Quarter 2008. The project is based upon the design and requirements specified by the UCSD AUVSI team that is entering the AUVSI UAS competition for UAV reconnaissance.

HSV Based Histogram Analysis of Targets Gives CORRECT Separation

As the title says, it is working, with the images running against a viable target i am able to separate the actual data perfectly for my sample case. The actual data, believe it or not, personally not keeping my hopes too high is being gathered this weekend. Apaarently the camera fell off the gimball on the flight last time...trust Aeronautical Engineers and you get burned.

Output from my Matlab Code:

1: 0.152674 Empty
2: 0.208643 Empty
3: 0.166598 Empty
4: 0.005949 Present
5: 0.000491 Present
6: 0.138655 Empty
7: 0.188792 Empty
8: 0.203062 Empty
9: 0.977584 Empty
10: 0.177460 Empty
11: 0.136012 Empty
12: 0.204911 Empty
13: 0.111032 Empty


Images 4 and 5 are the 2 with the little red coke lids. At the moment i am partitioning the data based on, if it is a target it must return a chi squared less than 0.1. I have also run a sample on a bunch of targets to get a viable chi squared value and then doubled this limit and compared it against a variety of samples.
