the following are patch 81 and 82. remove some spacing problems in my last patch, change t_y into k, negative math hurts my head. added a memset() call i missed the chance to last time, reversed conv[]'s order in memory... swapped X and Y in the image stored in conv[], so as to sequentialize memory accesses. gift 0.0.15a performs a gabor filter on an image once every two seconds. once these patches are committed, the CVS version will perform a gabor filter on an image every second. 100% faster, new and improved! :) my personal tree contains another 20% speed boost (down to 0.8 seconds per image). this is all measured on a P4M 2.2Ghz machine. i like accomplishing things. :) Julia Longtin <address@hidden>
