Wavelet compression is a technique used to compress video and audio signals. It works best for compressing high-contrast images and short-duration audio.

What is a wavelet image compression?
The whole process of wavelet image compression is performed as follows: An input image is taken by the computer, forward wavelet transform is performed on the digital image, thresholding is done on the digital image, entropy coding is done on the image where necessary, thus the compression of image is done on the ...
What is compression in image processing?
Image compression is a process applied to a graphics file to minimize its size in bytes without degrading image quality below an acceptable threshold. By reducing the file size, more images can be stored in a given amount of disk or memory space.
What's the definition of wavelet?
A wavelet is a waveform of effectively limited duration that has an average value of zero and nonzero norm. Many signals and images of interest exhibit piecewise smooth behavior punctuated by transients.
What is wavelet encoding?
Wavelet coding or compression is a form of data compression well suited for image compression (sometimes also video compression and audio compression). Wavelet compression can be either perfect (lossless) or lossy, where a certain loss of quality is accepted.
