An Autonomous System of Pattern and Colour Identification for the Visually Impaired

A visually impaired person can identify the shape of an object by the sense of touch but to recognize the colour and pattern of a textile would require the assistance of a helper. The paper proposes a system which can assist a person with visual disability in real time. The proposed system will be able to detect both the colour as well as pattern of the textile. For pattern detection, Hough line transform is implemented and for colour detection k-means clustering algorithm is implemented. Both used together can detect the colour and pattern, thus making the user independent of assistance of another. The system can detect patterns such as plain, vertical stripes, horizontal stripes, diagonal pattern and checks. Also the system detects the entire range of colours and the colour range is not limited. The main scope is to build an independent system which will be self-sufficient. The system also converts the identified data to audio for assistance to the visually impaired.
