VLOGRATIOVisionX V4 NAME

vlogratio − computes the ratio of positive to negative LOG response for a given set of candidates

SYNOPSIS

vlogratio [if=<inputimage>] [ic=<incandfile>] [of=<outcandfile>] [-t] [-v]

DESCRIPTION

vlogratio gets the response of scale-normalized LOG filter of a candidate size separately for positive and negative volumes of kernel support and computes their ratio. This ratio is the indicator of the candidate contrast.

OPTIONS

	if=		input image in short format
	ic=		input candidate file
	of=		output candidate file, containing all columns from the input candidate file plus additional column of computed ratio
	-t		use tab-separated format instead of default VisionX feature format both for input and output candidate files; input file may have arbitrary number of columns, however the first three must be the following: candidate index, x,y,z coordinates and diameter (in mm)
	-v		verbose mode; gives some runtime information
