Applies log transformation to pixel values.

Function

CuviStatus logTransform(const CuviImage& src,
                        CuviImage& dst,
                        const Cuvi32f c = 1.0f,
                        const CuviStream& stream = CuviStream());

Parameters

Name Type Description
src const CuviImage& Input Image
dst CuviImage& Destination Image
c const Cuvi32f Scaling value
stream const CuviStream& GPU stream ID for execution

Image Type Support

Input Output
8u 32f
16u 32f
32f 32f

Example

//Creating input images
CuviImage input = cuvi:io::loadImage(path), output;

const Cuvi32f c = 1.5f;

cuvi::colorOperations::logTransform(input,output,c);
