The first white pixel is relative to 0, all subsequent white pixels are relative to the one preceding it.Consider the (completely random) following white pixels in an image of 100x5:(0,47) ; (0,96) ; (1,32) ; (1,74) ; (2,06) ; (2,52)This yields locations as follows (totalWidth*row+column):047 = ((100 * 0) + 47)096 = ((100 * 0) + 96)132 = ((100 * 1) + 32)174 = ((100 * 1) + 74)206 = ((100 * 2) + 06)252 = ((100 * 2) + 52)This would them give you the following ASCII codes:474936423246Convert those to get the morse code symbols, and decode the morse.
