Counts the number of pixels within the given intensity range

Function

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

Parameters

Name Type Description
src const CuviImage& Input Image
count CuviScalar& Computed number of pixels within the given intensity range.
rangeMin const CuviScalar& Lower limit of the intensity range
rangeMax const CuviScalar& Upper limit of the intensity range
stream const CuviStream& GPU stream ID for execution

Image Type Support

Input Output
8uC1 CuviScalar
8uC3 CuviScalar
32fC1 CuviScalar
32fC3 CuviScalar

Sample

Count.PNG


Example

CuviImage gimg = cuvi::io::loadImage(path);

CuviScalar count;

const CuviScalar lowerBound(25.0, 10.0, 10.0);
const CuviScalar upperBound(100.0, 200.0, 150.0);


//Returns number of pixels within the given intensity range
cuvi::imageStatistics::countInRange(gimg, count, lowerBound, upperBound);
