If +.B -l +or +.B -v +is used, enough free memory to load three full frames +memory is required. +.P +.B blind-temporal-mean +is optimised for simplicity rather than memory usage. +.SH SEE ALSO +.BR blind (7), +.BR blind-temporal-arithm (1), +.BR blind-spatial-arithm (1), +.BR blind-arithm (1), +.BR blind-spatial-mean (1), +.BR blind-rewrite-head (1) +.SH AUTHORS +Mattias Andrée +.RI < maandree@kth.se > |
