Computes the maximum of image pixel values

Function

CuviStatus max(const CuviImage& src,
               Cuvi64f* maxValue,
               const CuviStream& stream = CuviStream());

Parameters

Name Type Description
src const CuviImage& Input Image
maxValue Cuvi64f* Maximum pixel value in the image
stream const CuviStream& GPU stream ID for execution

Image Type Support

Input Output
8uC1 Cuvi64f single value
8uC3 Cuvi64f three values

Sample

Max.PNG


Example

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

Cuvi64f* max = new Cuvi64f[gimg.channels()];


//Returns maximum pixel value	
cuvi::imageStatistics::max(gimg, max);
