Abstract: The visually impaired face various kinds of problems that normally sighted people don’t. Here a significant help is offered by android application for smartphone equipped with speech synthesizers. In this paper we have mentioned various problems faced by them and currently available solutions. We have used HSV model for more accurate processing of image. For training and recognizing image ANN algorithm is used. ANN facilitates faster training and detection of objects. To separate foreground and background from image sobel edge detection is used.
