/*********************************************
*
* file d:\cips\mainedge.c
*
* Functions: This file contains
* main
*
* Purpose:
* This file contains the main calling
* routine in an edge detection program.
*
* External Calls:
* gin.c - get_image_name
* tiff.c - read_tiff_header
* edge.c - quick_edge
* detect_edges
* edge2.c - homogeneity
* range
* variance
* difference_edge
* contrast_edge
* edge3.c - gaussian_edge
* enhance_edges
*
* Modifications:
* 2 February 1991 - created
* 1 January 1993 - added calls to
* range and variance functions.
