"description" = "As part of CERT's normal processing a face is found, rotated to a vertical position and cropped. Most later processing happens on the face patch, rather than the full image. The Patch Generator plugin can save face patches as individual image files.\nMost of the output formats are standard image types, but the RImage format is the same format that CERT uses internally for handling images. It is a simple, uncompressed file format.";
