* M10: enhance camera images: straighten a page from four corners (ocr.camera-perspective) Four corners on a page (any order, a convex quadrilateral) are warped to an upright rectangle that replaces what the page shows, read at the page picture's own resolution (at most 600 dpi) and kept at that physical size. One undoable step through Replace Pages, so comments, links and bookmarks stay. - geom: a pure 3x3 homography solve and corner ordering (no dependencies); collinear, concave and non-finite input gives None. - engine: camera::warp (bilinear, over white, capped at 40 MP) and Session::enhance_camera_page. - automation: page_enhance_camera (corners in top-left-origin points). - parity: ocr.camera-perspective is partial; the UI handles, automatic edge detection and contrast cleanup are still missing. Refs #1008. Co-Authored-By: Claude Opus 5.5 <[email protected]> * M10: Enhance camera image: drag four corners on the page, then Enhance page (ocr.camera-perspective) Scan & OCR ▸ Enhance camera image (ocr.enhance_camera) shows four corner handles on the current page, inset 5% from its edges, with what will be cut away dimmed. Enhance page straightens what they enclose through Session::enhance_camera_page (one undoable step); Cancel and Esc leave the page alone. The buttons float at the top right, clear of a centred page's corners, and the instructions are a notice, as for Crop. A command of its own, beside Enhance scanned file (ocr.enhance), which stays for scan correction (#1012). - ui-egui: camera_ui (handles, dimming, bar), QuickTool::EnhanceCamera, quick_tool "enhance-camera" for ui.state and the shot example. - Catalogs: the three new labels in every language with UI coverage (plus es, pl, zh-hant); ATTRIBUTION.toml hashes updated. - automation: page_enhance_camera is linked to the command. - parity: ocr.camera-perspective lists the command and the UI test. Refs #1008. Co-Authored-By: Claude Opus 5.5 <[email protected]> * M10: Enhance camera image finds the document's edges (ocr.camera-perspective) The corners now start on the photographed document's edges when they can be found, else inset 5% as before. camera_edges::detect_document, pure Rust and deterministic: shrink to 400 px, blur, Sobel edges thinned and thresholded against the 98th percentile; a Hough transform where each edge votes within 6 degrees of its own normal; pairs of near-horizontal and near-vertical lines make convex quadrilaterals (at least 12% of the picture), kept when every side lies on a matching edge along at least 55% of its length and scored by area times the square of the mean support; each side is then refitted through its edge points (total least squares). None when nothing convinces. - Session::detect_camera_corners (user space); page_enhance_camera finds the corners itself when `corners` is omitted and reports the corners it used and whether they were detected; the UI command starts from them. - Tests on synthetic photos: plain table, text on the sheet, wood grain with a shadow, strong perspective, a 30 degree turn, a sheet running off the picture, no document, white on white, bad input; end to end through the engine and the tool. - Parity notes: what is still missing (turning the result upright, rounded corners, clean-up). Refs #1008. Co-Authored-By: Claude Opus 5.5 <[email protected]> * M10: after Enhance page, rotate, crop or organize the page (ocr.camera-perspective) Enhance camera image no longer closes on Enhance page: the bar then offers rotate counterclockwise and clockwise for the enhanced page (one undo step each), Crop pages and Organize pages (which leave the tool for those tools), and Done; Esc leaves too. A photo of a card often comes out a quarter turn off until the page is turned upright automatically. The two icon buttons are named for screen readers. Every label already exists in the catalogs.
