In some article, you said that , The occurence of a given colour in a
particular block is treated as a binary feature. For 256*256 images there
are thus 56440 possible color block features.
But in your code(see below) ,you never treated it that way .
You just calculate 340 block features, of which each block has only one.
Am I right? If I am wrong ,please tell he where did you add them into the
array named featrue[feature_index]?
===========================================
/***** count the features *****/
/* we know that there will be a mode color for each block */
num_features = num_total_colour_blocks;
/* and there will be one for each non-zero histogram entry. Convert
histogram entries to range [0, FREQ_MAX] while we're at it */
for (i = 0; i < colmap_size; i++) {
col_histogram[i] =
(int)(rint(FREQ_MAX*(double)col_histogram[i]/(double)(square(image_size))));
if (col_histogram[i] != 0)
num_features++;
}
