Adriano	b20b11c029	perf: Numba JIT kernel per score_by_shift (2.1x speedup) ... - Nuovo modulo pm2d/_jit_kernels.py con _jit_score_by_shift Numba njit parallel + fastmath + boundscheck=False - Parallelizzazione per riga output (no race condition su acc) - Fallback automatico numpy se numba non installato - Warmup automatico al module import (evita JIT lag al 1 match) Benchmark clip.png (13 istanze): prima (numpy + threads): 1.55s dopo (numba + threads): 0.72s speedup: 2.1x Pipeline totale full (refine+subpix): 0.80s Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-24 01:30:31 +02:00
Adriano	b9a4d51fac	feat: PM2D standalone shape-based matcher ... Programma standalone Pattern Matching 2D con GUI cv2/tk + algoritmo puro riusabile. Due backend: - LineShapeMatcher (default): porting Python di line2Dup (linemod-style) - Gradient orientation quantized 8-bin modulo π + spreading - Feature sparse top-magnitude con spacing minimo - Score via shift-add vettorizzato numpy (O(N_features·H·W)) - Piramide multi-risoluzione con pruning varianti al top-level - Supporto mask binaria per modello non-rettangolare - EdgeShapeMatcher (fallback): Canny + matchTemplate multi-rotazione GUI separata da algoritmo. Benchmark clip.png (13 istanze): - Edge backend: 84s, 6/13 score ~0.3 - Line backend: 4.1s, 13/13 score 0.98-1.00 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-24 00:46:59 +02:00
