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 ...

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 ...

Ever since the necessity for international exchange of TV programs in electronic form rather than on film, there has been a need for standards conversion. Over the last half century, equipment has ...
