Abstract
Techniques to sample texels efficiently for an image effect may include determining a number of texels (kernel size) needed to compute a weighted average for an image effect on an image. The technique may further include selecting at least one mipmap generated by a graphics processing unit (GPU) according to a function of the determined kernel size. The function may also consider a threshold kernel size. The technique may further sampling texels, with the GPU, from the selected mipmap(s), and calculate the weighted average of the sampled texels to produce the image effect.
