Abstract -Now a day’s many systems are developed with various technologies which help the visually impaired people. Some systems are able to guide the user to their target but input from the user is not sufficient. Our paper deals with the state-of-art in field of technology assistive devices for blind people. It focuses on the use of image and video processing for converting visual data into rendering modality that will be appropriate for blind user. The system captures image of objects moving in front of blind people and generates a suitable count in the form of an audio signal which will be audible to the blind person and he can take the decision accordingly.
Keywords-Electronic travel aid, Charged coupled device, navigation aids, difference filters, threshold filters, histogram equalization, segmentation, feature extraction, erosion/dilation.
1. INTRODUCTION:
As life becomes more abundant the desire for higher levels of human welfare is being increased. Hence, interests in the quality of life become great not only for normal people but for handicapped people also. Handicapped people who have problems in their sensory systems live through various hardships, since human beings protect themselves from danger and respond to external stimuli by recognizing environmental information. Visual data contains a large number of information such as shape, color, roughness and motion of objects. The visual sensory system receives much more environmental information than any other sensory system. Hence, the visual
