Image Compression Using Discrete Tchebichef Transform Algorithm
─ The Discrete Tchebichef Transform (DTT) based on orthogonal Tchebichef polynomials can be an alternative to Discrete Cosine Transform (DCT) for JPEG image compression standard. The properties of DTT are not only very similar to DCT; it has also higher energy compactness and lower computational advantage using a set of recurrence relation. Through extensive simulation, image reconstruction acc...
متن کاملImage Coding Using Orthogonal Basis Functions
The transform properties of several orthogonal basis functions are analysed in detail in this report, and their performance compared using a set of grayscale test images, containing both natural and artificial scenes. Well-defined image quality measures are used to determine the type of images that are most suitable for compression for a given basis function. The particular transforms that we h...

The Discrete Tchebichef Transform (DTT) is a transform method based on the scaled orthogonal Tchebichef polynomials, which have applications recently found in image compression and pattern recognition. This report summarises the research carried out for the development of a fast DTT algorithm. The mathematical properties and the related algorithmic details of the Discrete Cosine Transform (DCT)...
متن کاملAn Image Dithering via Tchebichef Moment Transform
Many image display applications and printing devices allow only limited number of colours. They have limited computational power and storage to produce high quality outputs on high bit-depth colour image. A dithering technique is called for here in order to improve the perceptual visual quality of the limited bitdepth images. A dithered image is represented by a natural colour in the low bit de...
