Wavelet compression — is a form of data compression well suited for image compression (sometimes also video compression and audio compression). The goal is to store image data in as little space as possible in a file. Wavelet compression can be either lossless or… … Wikipedia
Image processing — is any form of signal processing for which the input is an image, such as photographs or frames of video; the output of image processing can be either an image or a set of characteristics or parameters related to the image. Most image processing… … Wikipedia
Image analysis — is the extraction of meaningful information from images; mainly from digital images by means of digital image processing techniques. Image analysis tasks can be as simple as reading bar coded tags or as sophisticated as identifying a person from… … Wikipedia
Image compression — is the application of Data compression on digital images. In effect, the objective is to reduce redundancy of the image data in order to be able to store or transmit data in an efficient form.Image compression can be lossy or lossless. Lossless… … Wikipedia
Wavelet — A wavelet is a mathematical function used to divide a given function or continuous time signal into different frequency components and study each component with a resolution that matches its scale. A wavelet transform is the representation of a… … Wikipedia
Wavelet transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. In mathematics, a wavelet series is a representation of a square integrable (real or complex valued) function by a certain orthonormal series generated by a wavelet … Wikipedia
Wavelet series — In mathematics, a wavelet series is a representation of a square integrable (real or complex valued) function by a certain orthonormal series generated by a wavelet. This article provides a formal, mathematical definition of an orthonormal… … Wikipedia
Image fusion — In computer vision, Multisensor Image Fusion is the process of combining relevant information from two or more images into a single image. The resulting image will be more informative than any of the input images. In remote sensing applications,… … Wikipedia
Image conversion — A massive number of image file formats are available for storing graphical data, and, consequently, there are a number of issues associated with converting from one image format to another. The key issues associated with image conversion are file … Wikipedia
Wavelet — Ondelette En mathématiques, une ondelette est une fonction de carré sommable sur l espace euclidien , le plus souvent oscillante et de moyenne nulle, choisie comme outil d analyse et de reconstruction multi échelle. Les ondelettes se rencontrent… … Wikipédia en Français
