A lossy compression method used for color images and video. Instead of compressing small blocks of 8x8 pixels (64 bits) as in JPEG and MPEG, the wavelet algorithms compress the entire image with ...
In many fields of study, from science and engineering to economics and psychology, we need to analyze data so that we can discover underlying patterns and information. A common way of doing this is to ...
This paper presents an optimized speech compression algorithm using discrete wavelet transform, and its real time implementation on fixed-point Digital Signal Processor (DSP). The optimized speech ...
