TODO LIST Please send any ideas. Next release (0.4x) - vectorize recognition (big step!, relation to other OSS?) (find min distance to ideal vector patterns, start with <>()) - frame_nn is marking only the borders like frame_vector and removed later - handle broken and glueed chars by the database algorithm (-m 256 -m 130) - improve get_line2(), implement distance_to_point and distance_to_line - dot-matrix printouts (examples/matrix.jpg) (german: Nadeldrucker) - examples/inverse.pcx + examples/rotate45.pcx by nearest-box-to-line alg. or mean nearest box (or its 4 edges) directions, rotate only boxes (by creating new greater boxes and tread as new image) - proof replacement of getTextLine by getXMLline via pipe(?) or stdout is pipe available on all platforms? - docu about ispell using via XML (what needed, test in gocr.tcl) - replace rest of UNDEFINED in unicode.c by its correct strings - add probability for box->m1..m4 (to reduce errors caused by bad line-scan) call line detection function second time to improve unsure line data Next release (0.5x) - reduce pixel data by vectorization (big change, faster) - writing images through pipes (like reading) - using dictionary (optional) for replacing not recognized chars - Karsten.Hilbert@gmx.net: use ORChie WordBox-format see http://http.cs.berkeley.edu/~fateman/kathey/ocrchie.html aspell instead of ispell Near future: (planned version) - rewrite install-routine - perspective distortion (for cameras) - genetic algorithms engine (already in development, 0.8?). It includes feature extraction and classification - support for other languages (may affect context_correction(), etc) (0.6?) - support for diagramation. Can be done using the Unicode+new stuff. I (bbg) have some ideas. Far future: - gimp plugin - color support - Braille detection (usefull for blinds?) see: American Journal of Physics Vol. 70, No. 7, p 684-688 (2002) or use special foils - read image in smaller parts, to reduce memory usage. - frames should be recognized - better distance function (comparision of characters) - detection of orientation (i.a. 90,180,270deg rotation) - picture extraction - math formula detection, font type detection - handwritten texts (blockletters) --- uff, really a lot of work --- - Feel free and add your suggestions and wishes, or tell me, what is the most important point for you.
