As stated in our initial proposal we have achieved the following. Filters Colorspace Conversion Blur Laplacian Sharpen Gabor oriented filters Any kernel of any size Gaussian and Laplacian Pyramids Data Packing Color conversion, pack 2 pixels in 1, supported 'pack' filters, and unpack Edge Detection Canny Laplacian of Gaussian Feature Detection Harris Corner Detection Image Segmentation Isoperimetric graph partition Matrix Operations Min/Max Dense Matrix Multiplication Sparse Matrix Multiplication Vector-Matrix Multiplication Vector Dot Product Conjugate Gradient Solver The filters, color conversion, edge detection and feature detection was developed by Michael Lehr, and the Matrix operations and Image Segmentation was developed by Ikkjin Ahn.   Ikkjin Ahn, Michael Lehr http://gpuvision.sourceforg.net/ gpuvision@gmail.com July 1, 2005
