.TH BLIND-MOSAIC-EDGES 1 blind .SH NAME blind-mosaic-edges - Find edges in a mosaic video .SH SYNOPSIS [-xy] .B blind-mosaic-edges .SH DESCRIPTION .B blind-mosaic-edges reads a mosaic pattern from stdin and set the values of each change to 1 at edges and to 0 everywhere else. .IR mosaic-stream-edges . .SH OPTIONS .TP .B -x At the left and right edges of the video, wrap around to the opposite edges. .TP .B -y At the upper and lower edges of the video, wrap around to the opposite edges. .SH REQUIREMENTS .B blind-mosaic-edges requires enough free memory to load one full frame into memory and 1 bit per pixel on a frame. A frame requires 32 bytes per pixel it contains. .B blind-mosaic-edges is optimised for simplicity rather the memory usage. .SH SEE ALSO .BR blind (7), .BR blind-mosaic-corners (1), .BR blind-hexagon-tessellation (1), .BR blind-rectangle-tessellation (1), .BR blind-triangle-tessellation (1), .BR blind-repeat-tessellation (1), .BR blind-mosaic (1) .SH AUTHORS Mattias Andrée .RI < maandree@kth.se >
