We are particularly interested in segmentation and thresholding algorithms for use in a portable text-to-speech system for the vision impaired. Reading low-contrast LCD displays is the target application. We present a low-complexity method for automatically extracting text of any size, font, and format from images acquired by a video camera that may be poorly focused and aimed, under conditions of inadequate and uneven illumination. The new method consists of fast thresholding that combines a local variance measure with a logical stroke-width method, and with a low-complexity statistical and contextual noise segmentation. The performance of this method compares favorably with more complex methods for the extraction of characters from scene images. Initial results are encouraging for application in a robust portable reader. <\/jats:p>","DOI":"10.1142\/s0218001400000106","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T07:03:21Z","timestamp":1027753401000},"page":"113-135","source":"Crossref","is-referenced-by-count":7,"title":["LOW-COMPLEXITY CHARACTER EXTRACTION IN LOW-CONTRAST SCENE IMAGES"],"prefix":"10.1142","volume":"14","author":[{"given":"LOWELL L.","family":"WINGER","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering,  University of Toronto, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JOHN A.","family":"ROBINSON","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Applied Science, Memorial University of Newfoundland, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
