Low-Complexity Scalable DCT Image Compression
We have developed a scalable image compression scheme with a good performance-complexity trade-off. Like JPEG, it is based on the 8 × 8 block discrete cosine transform (DCT), but...

A jointly optimal fractal/DCT compression scheme
In this paper a hybrid fractal and Discrete Cosine transform (DCT) coder is developed. Drawing on the ability of DCT to remove inter-pixel redundancies and on the ability of fracta...

Modeling Marginal Distributions of Gabor Coefficients: Application to Biometric Template Reduction
Abstract. Gabor filters have demonstrated their effectiveness in automatic face recognition. However, one drawback of Gabor-based face representations is the huge amount of data th...

An error resilient scheme for image transmission over noisy channels with memory
Abstract— This correspondence addresses the use of a joint sourcechannel coding strategy for enhancing the error resilience of images transmitted over a binary channel with addit...

Scan order and quantization for 3D-DCT coding
Two types of coders dominate the field of video compression research today: well-established hybrid coders, that are in the core of all MPEG and H.26X standards, and emerging thr...
