Function:CountInRange

Counts the number of pixels within the given intensity range

Function

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

Parameters

Name	Type	Description
image	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	Cuvi64f*	Lower limit of the intensity range
rangeMax	Cuvi64f*	Upper limit of the intensity range
stream	CuviStream*	GPU stream ID for execution

Image Type Support

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

Sample

Example

CuviImage* gimg = new CuviImage(size, depth, nChannels); Cuvi32u* count = new Cuvi32u[nChannels]; Cuvi32f lowerBound = 25; Cuvi32f upperBound = 100; //Upload input data gimg->upload(hostImg->imageData, hostImg->widthStep); //Returns number of pixels within the given intensity range cuvi::arithmeticLogical::countInRange(gimg, &count, lowerBound, upperBound);
