Скоростные Пазлы – 3 (Fast Puzzles – 3)
bug-makers
Task: web-based 16x16 (256-piece) timed jigsaw puzzle; API serves the original image plus shuffled base64 JPEG pieces and must be solved in 60s. Solution: localize each piece in the original with FFT cross-correlation template matching (integral-image energy term), then Hungarian assignment of pieces to grid cells to enforce a valid permutation.
