In the two previous posts, I identified some anomalies with Matlab’s implementation of bilinear interpolation downsampling at reduction ratios that are integral powers of two. I also observed smaller, but similar, anomalies with bicubic, Lanczos 2, and Lanczos 3 downsampling. Today I set out to find out if the Photoshop implementations of bilinear interpolation evinced… [Read More]
