a selected few image processing applications. Optical Character Recognition is the translation of images of handwritten‚ typewritten or printed text into machine-editable text. Then I have introduced the captcha that we so frequently encounter in common websites. An algorithm trying to solve or break a captcha has been explained. Face detection is a growing and an important tool in security these days. It must be applied before face recognition. There are many methods for recognizing faces

printed questionnaires is by using a scanning device called an optical data reader which in turn uses optical mark recognition forms‚ which are also called mark sense forms. Using these forms for printed questionnaires enables accurate census taking by just scanning the forms. In this process‚ there is no room for human error and the results are accurate. In a situation such as taking a telephone survey‚ methods using voice recognition devices are used. This type of input device recognizes human speech
