Left shift pixel values of the input image by specified constant value.

Function

CuviStatus SHL(const CuviImage& src,
               const Cuvi32s value,
               CuviImage& dst,
               const CuviStream& stream = CuviStream());

Parameters

Name Type Description
src const CuviImage& Input Image
value const CuviImage& Shift value
dst CuviImage& Resultant Image
stream const CuviStream& GPU stream ID for execution

Image Type Support

Input Output
8uC1 8uC1
8uC3 8uC3
16uC1 16uC1
16uC3 16uC3

Sample

Example

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

CuviImage output;

//Left shift 2 bits
cuvi::arithmeticLogical::SHL(input, 2, output);

//The above can also be achieved by using shift operator
output = input<<2;
