It works by filling in the pixels that - * comprise the logo with neighboring pixels. The transform is very loosely - * based on a gaussian blur, but it is different enough to merit its own - * paragraph later on. It is a major improvement on the old delogo filter as it - * both uses a better blurring algorithm and uses a bitmap to use an arbitrary - * and generally much tighter fitting shape than a rectangle. - * - * The logo removal algorithm has two key points. The first is that it - * distinguishes between pixels in the logo and those not in the logo by using - * the passed-in bitmap. Pixels not in the logo are copied over directly without - * being modified and they also serve as source pixels for the logo - * fill-in. Pixels inside the logo have the mask applied. - * - * At init-time the bitmap is reprocessed internally, and the distance to the - * nearest edge of the logo (Manhattan distance), along with a little extra to - * remove rough edges, is stored in each pixel. This is done using an in-place - * erosion algorithm, and incrementing each pixel that survives any given - * erosion. Once every pixel is eroded, the maximum value is recorded, and a - * set of masks from size 0 to this size are generaged. The masks are circular - * binary masks, where each pixel within a radius N (where N is the size of the - * mask) is a 1, and all other pixels are a 0. Although a gaussian mask would be - * more mathematically accurate, a binary mask works better in practice because - * we generally do not use the central pixels in the mask (because they are in - * the logo region), and thus a gaussian mask will cause too little blur and - * thus a very unstable image. - * - * The mask is applied in a special way. Namely, only pixels in the mask that - * line up to pixels outside the logo are used. The dynamic mask size means that - * the mask is just big enough so that the edges touch pixels outside the logo, - * so the blurring is kept to a minimum and at least the first boundary - * condition is met (that the image function itself is continuous), even if the - * second boundary condition (that the derivative of the image function is - * continuous) is not met. A masking algorithm that does preserve the second - * boundary coundition (perhaps something based on a highly-modified bi-cubic - * algorithm) should offer even better results on paper, but the noise in a - * typical TV signal should make anything based on derivatives hopelessly noisy. - */ - -#include "libavutil/imgutils.h" -#include "libavutil/opt.h" -#include "avfilter.h" -#include "formats.h" -#include "internal.h" -#include "video.h" -#include "bbox.h" -#include "lavfutils.h" -#include "lswsutils.h" - -typedef struct { - const AVClass *class; - char *filename; - /* Stores our collection of masks.
