XThis tool tries to find a suitable clipping border for a series of gray
Ximages. It is very useful to automatically extract clipping values for
Xtranscoding a movie if the source frame is encoded with black bars.
X
XA border around an image is defined by a rectangular and homogenous valued
Xarea extending from each edge of the image (e.g. the black bars around a movie
Xframe). For each image the largest clip border is determined and the smallest
Xcommon region of the image series is returned. Empty images or images with no
Xvalid clipping region are ignored.
X
XTo cope with noisy regions in the black border areas, the region finding
Xalgorithm does not simply cut away all regions with purely zero values, but it
Xuses a threshold in the absolut gradient sum along rows and columns as a hint
Xfor the begin of real image contents.
X
XYou need a frame processing tool like transcode to actually perform the
Xclipping operation.
X
XThe program assumes that all images have the same size!
