Affine rotate

WebRotation and translation of images are among the most basic operations in image editing. Both fall under the broader class of Affine transformations. Before studying more complex transformations, you should therefore first learn to rotate and translate an image, using the functions available in OpenCV. In their applications to digital image processing, the affine transformations are analogous to printing on a sheet of rubber and stretching the sheet's edges parallel to the plane. This transform relocates pixels requiring intensity interpolation to approximate the value of moved pixels, bicubic interpolation is the standard for image transformations in image processing applications. Affine transformations scale, rotate, translate, mirror and shear images as shown in the following exa…
