Function:CountInRange

Counts the number of pixels within the given intensity range

Function

CuviStatus countInRange(const CuviImage& src, Cuvi32u* count, const Cuvi32f rangeMin, const Cuvi32f rangeMax, const CuviStream& stream = NULL);

Parameters

Name	Type	Description
src	const CuviImage&	Input Image
count	Cuvi32u*	Computed number of pixels within the given intensity range. Returns an array of 3 values in case of 3-channel image
rangeMin	const Cuvi32f	Lower limit of the intensity range
rangeMax	const Cuvi32f	Upper limit of the intensity range
stream	const CuviStream&	GPU stream ID for execution

Image Type Support

Input	Output
8uC1	Cuvi32u single value
8uC3	Cuvi32u three values

Sample

Example

CuviImage* gimg = cuvi::io::loadImage(path); Cuvi32u* count = new Cuvi32u[gimg.channels()]; const Cuvi32f lowerBound = 25.0f; const Cuvi32f upperBound = 100.0f; //Returns number of pixels within the given intensity range cuvi::imageStatistics::countInRange(gimg, count, lowerBound, upperBound);
