* manual_threshold_segmentation(...
*
* This function segments an image using thresholding
* given the hi and low values of the threshold
* by the calling routine. It reads in an image
* and writes the result to the output image.
*
* If the segment parameter is 0, you only
* threshold the array - you do not segment.
