WebStarting with the 9.0 version, Intel IPP enables you to use the ippiWarpAffine functions to implement rotation of an image using pre-calculated affine coefficients based on rotation parameters (angle, x-, y-shifts ). To obtain affine coefficients for the specified rotation parameters, you can apply the ippiGetRotateTransform ... WebLinear Interpolation. This is the fastest and least accurate interpolation mode. The pixel value in the destination image is set to the value of the source image pixel closest to the point. (xS,yS):D(xD,yD) = S(round (xS), round (yS)). The linear interpolation is slower but more accurate than the nearest neighbor interpolation. greatest common factor of 9 12 and 21
