Web23 de jul. de 2010 · Image warping is a very useful and important image processing function that we use all the time. It is often used, when calibrated, to remove distortions such as perspective projection and lens distortion. Many pattern matching libraries make use of affine image warps to compute image alignment. electric elevated stoveWebMulti-Draw Indirect Sample. Performance.
