An Image Sonification Method Based on Lifting Wavelet Transform
Xu Wang · Journal of Northeastern University · 2011
In the conventional image sonification method the mapping features selected in the space domain and the simple sound coding make the blind difficult to understand such a sound.A method based on the transform domain is therefore presented,where the low frequency coefficients of wavelet transform are mapped into the frequency and sound length so as to represent the image in electronic music.Experimental results showed that the blind is able to understand the images mapped into the auditory representation.Moreover,the sound is pleasing to ear and enjoyable.
