The colorthresholding function compares the color space values of
the source image with low and high threshold values, and returns either
255 or 0 as the output.

Parameter Descriptions
The table below describes the template and the function parameters.
Parameter Description SRC_T Input pixel type. Only 8-bit, unsigned, 3 channel is supported (XF_8UC3). DST_T Output pixel type. Only 8-bit, unsigned, 1 channel is supported (XF_8UC1). MAXCOLORS Maximum number of color values ROWS Maximum height of input and output image COLS Maximum width of input and output image. Must be a multiple of 8, for 8 pixel mode. NPC Number of pixels to be processed per cycle. Only XF_NPPC1 supported. XFCVDEPTH_IN_1 Depth of input image XFCVDEPTH_OUT_1 Depth of output image _src_mat Input image _dst_mat Thresholded image low_thresh Lowest threshold values for the colors high_thresh Highest threshold values for the colors
