Resize the image size conversion void cvResize (const CvArr* src, CvArr* dst, int interpolation = CV_INTER_LINEAR) src input image. Dst output image. Interpolation interpolation method:* CV_INTER_NN- nearest neighbor interpolation,* CV_INTER_LINEAR- bilinear interpolation (default use)* CV_INTER_AREA- resampling using pixel relationship. The time when the image reduction, the method avoids ripple appears. When the image is zoomed in, like CV_INTER_NN method ..* CV_INTER_CUBIC- cubic interpolation. Function cvResize change the size of the image src and dst are the same size. If the setting ROI, will be general support functions ROI.
