This past Sunday we created a lot of sample targets to use in acquiring images. We have almost every letter/number currently and should have the remainder finished next weekend. The targets are made out of plywood and painted solid colors.
Currently we plan to fly on Wednesday and acquire video of many of the targets from various angles and extract frames to create individual images.
For the Wednesday update we will have video and images of the sample targets.
I have also started to review some papers on shape/character recognition, specifically: Invariant pattern recognition using radon, dual-tree complex wavelet and Fourier transforms. It is a fairly complex paper that presents rotation invariant recognition for even highly noisy images. I am currently in the process of becoming familiar with the Radon Transform, which in some cases is very similar to the Hough transform.
