      1 .TH BLIND-TEMPORAL-ARITHM 1 blind
      2 .SH NAME
      3 blind-temporal-arithm - Perform simple arithmetic over all frames in a video for each pixel
      4 .SH SYNOPSIS
      5 .B blind-temporal-arithm
      6 .I operation
      7 .SH DESCRIPTION
      8 .B blind-temporal-arithm
      9 reads a video from stdin and applies an arithmetic
     10 operation over all frames in the video, for each
     11 pixel, and prints the resulting single-frame video
     12 to stdout.
     13 .SH OPERATIONS
     14 .TP
     15 .B add
     16 Calculate the sum of the operands.
     17 .TP
     18 .B mul
     19 Calculate the product of the operands.
     20 .TP
     21 .B min
     22 Select the lowest operand.
     23 .TP
     24 .B max
     25 Select the highest operand.
     26 .SH REQUIREMENTS
     27 .B blind-temporal-arithm
     28 requires enough free memory to load one full frames memory.
     29 A frame requires 32 bytes per pixel it contains.
