An Embedded Application for Degraded Text Recognition
This paper describes a mobile device which tries to give the blind or visually impaired access to text information. Three key technologies are required for this system: text detection, optical character recognition, and speech synthesis. Blind users and the mobile environment imply two strong constraints. First, pictures will be taken without control on camera settings and a priori information ...
متن کاملan application of fuzzy logic for car insurance underwriting
در ایران بیمه خودرو سهم بزرگی در صنعت بیمه دارد. تعیین حق بیمه مناسب و عادلانه نیازمند طبقه بندی خریداران بیمه نامه براساس خطرات احتمالی آنها است. عوامل ریسکی فراوانی می تواند بر این قیمت گذاری تاثیر بگذارد. طبقه بندی و تعیین میزان تاثیر گذاری هر عامل ریسکی بر قیمت گذاری بیمه خودرو پیچیدگی خاصی دارد. در این پایان نامه سعی در ارائه راهی جدید برای طبقه بندی عوامل ریسکی با استفاده از اصول و روش ها...
Degraded text recognition using word collocation
A relaxation-based algorithm is proposed that improves the performance of a text recognition technique by propagating the in uence of word collocation statistics. Word collocation refers to the likelihood that two words co-occur within a xed distance of one another. For example, in a story about water transportation, it is highly likely that the word \river" will occur within ten words on eithe...
متن کاملWord Image Matching in a Methodology for Degraded Text Recognition
A technique for the use of global context in text recognition is presented that determines equivalences between word images in a passage of text. Initial hypotheses for the identities of words are then generated by matching the word groups to language statistics that predict the frequency at which certain words will occur. This is followed by a recognition step and a relaxation-based control st...
متن کاملWord Image Matching as a Techique for Degraded Text Recognition
A technique is presented that determines equivalences between word images in a passage of text. A clustering procedure is applied to group visually similar words. Initial hypotheses for the identities of words are then generated by matching the word groups to language statistics that predict the frequency at which certain words will occur. This is followed by a recognition step that assigns ide...
