A blind guidance system based on GCADSF image enhancement and music display

摘要

There are some problems in the conventional blind guidance systems, such as massive mapping data, low mapping efficiency and simple sound coding. And they are easily affected by noise. These make the blind difficult to use the system. To solve these problems, a system is presented based on GCADSF image enhancement and music display. GCADSF model uses an exponential function which monotonically decreases with the gradient module to control the diffusion in the vertical direction of the image gradient. So it protects the image details as the edges are enhanced and the noise is filtered. The enhanced image is mapped into electronic music. Experimental results showed that the system has higher recognition rates for the blind's recognizing the image contents.
