stretchtbl - generates table simulating two exponential functions applied to an image.  

SYNOPSIS

stretchtbl [exp [percentage [exp]]] <inseq > tbl_name  

DESCRIPTION

stretchtbl - builds a table of values corresponding to two exponential functions applied to the gray-levels in the image. The first function is applied to a percentage of the gray-levels, starting with zero, and the second function is applied to the remaining gray-levels. Use mapapply to filter the image through this map.
