Image size Transformation
void cvresize (const cvarr* SRC, cvarr* dst, int
Interpolation=cv_inter_linear);
Src
Enter an image.
Dst
The output image.
Interpolation
Difference method:
Cv_inter_nn-Nearest Neighbor difference value,
cv_inter_linear-bilinear difference value (default use)
Cv_inter_area-resampling using pixel relationships. When the image shrinks, the method
You can avoid the appearance of ripples. When the image is zoomed in, it resembles the Cv_inter_nn method:
cv_inter_cubic-cubic difference value.
The function cvresize changes the image src size to get the same sizes as DST. If set
ROI, the function will support the ROI as usual.
