ABSTRACT: Recognizing colors is a concerning problem for the visually impaired person. The aim of this paper is to convert colors to sound and vibration in order to allow fully/partially blind people to have a ‘feeling’ or better understanding of the different colors around them. The idea is to develop a device that can produce vibration for colors. The user can also hear the name of the color along with ‘feeling’ the vibration. Two algorithms were used to distinguish between colors; RGB to HSV color conversion in comparison with neural network and decision tree based machine learning algorithms. Raspberry Pi 3 with Open Source Computer Vision (OpenCV) software handles the image processing. The results for RGB to HSV color conversi...
