Re-sizes input image to fit into the output image size.

Function

CuviStatus resize(const CuviImage& src,
                  CuviImage& dst, 
                  CuviInterpolationType inter = CUVI_INTER_LINEAR,
                  const CuviStream& stream = CuviStream());


Parameters

Name Type Description
src const CuviImage& Input Image
dst CuviImage& Output Image
inter CuviInterpolationType Type of interpolation to use for re-sizing. Supports:
CUVI_INTER_NN
CUVI_INTER_LINEAR
CUVI_INTER_CUBIC
stream const CuviStream& GPU stream ID for execution

Image Type Support

Input Output
8uC1 8uC1
8uC3 8uC3
16uC1 16uC1
16uC3 16uC3
32fC1 32fC1
32fC3 32fC3


Samples

Input Image (Width = W, Height = H)
Resized Image (width =0.78625*W, height= 0.78625*H)
Input Image (Width = W, Height = H)
Resized Image (width = 1.2*W, height= 1.75*H)


Example

CuviImage gimg = cuvi::io::loadImage(path);
 
const Cuvi32f xScale = 0.5f, yScale = 0.7f;
 
const Cuvi32s newWidth = static_cast<Cuvi32s>(gimg.width() * xScale);
const Cuvi32s newHeight = static_cast<Cuvi32s>(gimg.height() * yScale);
 
CuviImage gout(newWidth,newHeight,gimg.type());
 
 
//Re-sizing input image to fit output container using bicubic interpolation
cuvi::geometryTransforms::resize(gimg,gout, CUVI_INTER_CUBIC);
