[help-gfit]About the number of the features

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++;
    }
