OVERVIEW Computer-vision arithmetic without a model or an image library: read dimensions from a file header, convert boxes between annotation formats, plan a resize with the box transform, check colour contrast — and, with a licence, run NMS and score detections. Pure arithmetic and header parsing.

KEY CAPABILITIES • image_probe — format, width, height, aspect ratio and orientation from the first bytes of a PNG, JPEG, GIF, BMP or WebP; a base64 prefix is enough and nothing is decoded • bbox_convert — COCO, Pascal VOC and YOLO in any direction, with rejected boxes reported • resize_plan — exact scale, padding and crop for a fixed model input, plus the box transform • colour_check — WCAG 2 contrast ratio with AA / AAA verdicts • Licence: nms (deterministic greedy non-maximum suppression) + detection_metrics (per-class precision, recall, F1 and Pascal VOC-style average precision, with the working shown)

USE CASES • Fix a dataset whose boxes were exported in the wrong format before training • Plan letterboxing for a fixed-size detector input and carry the labels along • Check a UI palette against WCAG before an audit does

WHO THIS IS FOR ML engineers, annotation teams and agent builders who want deterministic CV math instead of guessed numbers.

WHY MOLTLINE • Every tool tested against known answers before release • One All-Access licence ($19/month, settled in cryptocurrency through NOWPayments) unlocks the premium tools on every Moltline server - send it in the X-Moltline-License header • Support: first response <24h, confirmed defects fixed <30 days
