Article Overview Flat Field Correction (FFC) is a common technique in image processing used to eliminate uneven illumination or sensor response non-uniformity in images. FFC typically requires a flat field image, which is captured under uniform lighting conditions, to correct the target image. The following is a simplified FFC program based on MATLAB, designed to … Read more

Malbolge: A programming language from “hell” that can actually be used for encryption? What is Malbolge? Do you really want to know? If programming languages have a “ceiling of complexity”, then Malbolge is definitely the champion. This language has never had a truly functional program written by its creator, Ben Olmstead! Yes, you heard it … Read more
