Image processing
adaptive coding
Software; Image processing
The application of two or more image compression techniques to a single image, based on properties of different parts of the image.
Preprocessing
Software; Image processing
An operation performed before a primary process; for example, in pattern recognition, processing in which patterns are simplified to make classification easier.
Digitised image
Software; Image processing
An image t h a t has been converted into an array of pixels, each of which has an associated value called its grey level. Note: A digital image may be referred to as an image when the intended ...
Lossless encoding
Software; Image processing
Any image compression technique that represents grey levels compactly but permits exact reconstruction of the image; for example, contour encoding; run length encoding.
Quantization
Software; Image processing
In image processing, a process in which each pixel in an image is assigned one of a finite set of grey levels.
Sharpening
Software; Image processing
Any image enhancement technique in which the effect of blurring in the original image is reduced.
Smoothing
Software; Image processing
Any image enhancement technique in which the effect of noise in the original image is reduced.
