An Efficient Implementation of Hierarchical Image Coding

ABSTRACT The third issues are compatibility and scalability. Different bitstreams, having multiple resolution versions of the image/video, are more desirable to different users with various computational capabilities. An efficient technique for hierarchical image coding is proposed, which divides an image into its multiple resolution versions with minimum hardware cost. Since the proposed techn...

JPEG compliant efficient progressive image coding

Among the different modes of operations allowed in the current JPEG standard, the sequential and progressive modes are the most widely used. While the sequential JPEG mode yields essentially the same level of compression performance for most encoder implementations, the performance of progressive JPEG depends highly upon the designed encoder structure. This is due to the flexibility the standar...

Normalized Image Representation for Efficient Coding

In this paper we propose an adaptive non-linear image representation based on the divisive normalization of localfrequency transforms used in contrast masking models. This normalized representation has two effects: (1) it increases the statistical independence of the coefficients of the representation and (2) it is Euclidean from a perceptual point of view. Experimental results show that reduci...

Natural image statistics and efficient coding.

Natural images contain characteristic statistical regularities that set them apart from purely random images. Understanding what these regularities are can enable natural images to be coded more efficiently. In this paper, we describe some of the forms of structure that are contained in natural images, and we show how these are related to the response properties of neurons at early stages of th...
