Автору спасибо, на основе его и Nomer'овского кода решил свои маленькие проблемы с одним надоедливым сервисом. 
Распознает капчу из букв и цифр типа 
PHP код:
<?
//coded by rikki
function pwntcha($image) {
define("LETTERS" , "...##.....####...##..##.##....####....####....############....####....####....########..##...##.##....####...##.######..##...##.##....####....####...##.######....#####..##...####.....###......##......##......##......##.....#.##...##..#####.######..##...##.##....####....####....####....####....####....####...##.######..#######.##......##......##......######..##......##......##......##......#######.##########......##......##......######..##......##......##......##......##........#####..##...####......##......##......##...#####....####....##.##...##..#####.##....####....####....####....############....####....####....####....####....##################################################################################...####......##......##......##......##......##......##..#...##..##.##....###...##....####...##.##..##..##.##...####....####....##.##...##..##..##...##.##....####......##......##......##......##......##......##......##......##......#######.##....#####..#############.##.####.##.####.##.####....####....####....####....####....#####...######..######..####.##.####.##.####..######...#####...#####....##................................................................................#######.##....####....####....#########.##......##......##......##......##........####...##..##.##....####....####....####....####.##.####..####.##..##...####.########.##....####....####....#########.#####...##..##..##...##.##....####....##.######.##....####......##.......######.......##......##......####....##.######.########...##......##......##......##......##......##......##......##......##...##....####....####....####....####....####....####....####....##.##..##...####..##....####....####....##.##..##..##..##..##..##...####....####.....##......##...##....####....####....####....####.##.####.##.####.##.#############..#####....####....####....##.##..##...####.....##......##.....####...##..##.##....####....####....####....##.##..##...####.....##......##......##......##......##......##...#######......##......##.....##.....##.....##.....##.....##......##......#######...####...##..##.##....##......##.....##.....##.....##.....##.....##.....########.#####..##...##.......##.....##....###.......##.......##......####...##..#####.......##.....###....####...##.##..##..##.##...##.########.....##......##......##.#######.##......##......##.###..###..##.......##......####....##.##..##...####....####...##..##.##....#.##......##.###..###..##.##....####....##.##..##...####..########......##......##.....##.....##.....##.....##.....##.....##......##........####...##..##.##....##.##..##...####...##..##.##....####....##.##..##...####....####...##..##.##....####....##.##..###..###.##......##.#....##.##..##...####..
