.TH BLIND-VECTOR-PROJECTION 1 blind .SH NAME blind-vector-projection - Calculate the projection or rejection of colours in a video .SH SYNOPSIS .B blind-vector-projection [-r | -s] .I plane-stream .SH DESCRIPTION .B blind-vector-projection reads a video from stdin and a video from .IR plane-stream , and calculates the projection of the colours from stdin onto the colours from .I plane-stream and prints the resulting video to stdout. .P If stdin is longer than .IR plane-stream , the remainder of stdin is printed without any changes. If stdin is shorter than .IR plane-stream , the remainder of .I plane-stream is ignored but may be partially read. .SH OPTIONS .TP .B -r Calculate the vector rejection instead of the vector projection. .TP .B -s Calculate the scalar projection instead of the vector projection. The scalar projection is stored in all four channels. .SH SEE ALSO .BR blind (7), .BR blind-arithm (1), .BR blind-norm (1), .BR blind-dot-product (1), .BR blind-cross-product (1), .BR blind-quaternion-product (1) .SH AUTHORS Mattias Andrée .RI < maandree@kth.se >
