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 ...

Most people think of JPEG XS as a low-latency compression codec — and it is. But there is a capability built into its wavelet architecture that goes far beyond simple compression: the ability for any ...

Figure 1. JPEG 2000 applications. Click here to see an enlarged diagram. The JPEG 2000 standard, finalized in 2001, defines a new image-coding scheme using compression techniques based on wavelet ...

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 ...

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 ...
