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 ...
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 ...
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 ...
An effective method for compression of ECG signals, which falls within the transform lossy compression category, is proposed. The transformation is realized by a fast wavelet transform. The ...
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 ...
