Function

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

Parameters

Name Type Description
src const CuviImage& Input Image
sum Cuvi64f* Sum of all pixel values of the image
stream const CuviStream& GPU stream ID for execution

Image Type Support

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

Sample

Error creating thumbnail: Unable to save thumbnail to destination

Example

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

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


//Sum of all pixel values
