Low Rate and Scalable Image Coding with Redundant Representations
New breakthroughs in image coding possibly rely in signal decomposition through non-separable basis functions. The work proposed in this paper provides an adaptive way of representing images as a sum of two-dimensional features. It presents a low bit-rate image coding method based on a Matching Pursuit expansion, over a dictionary built on anisotropic refinement and rotation of contour-like ato...
متن کاملVery low bit rate image coding using redundant dictionaries
Very low bit rate image coding is an important problem regarding applications such as storage on low memory devices or streaming data on the internet. The state of the art in image compression is to use 2-D wavelets. The advantages of wavelet bases lie in their multiscale nature and in their ability to sparsely represent functions that are piecewise smooth. Their main problem on the other hand,...
متن کاملHighly Flexible Image Coding Using Non-linear Representations
This paper presents a new image representation method based on a Matching Pursuit expansion over a dictionary built on anisotropically refined atoms. New breakthroughs in image coding certainly rely on truly multidimensional signal decompositions, and the coder proposed in this paper provides an adaptive way of representing images as a sum of two-dimensional features. It is shown to provide ver...
متن کاملImage coding using redundant dictionaries
This chapter discusses the problem of coding images using very redundant libraries of waveforms, also referred to as dictionaries. We start with a discussion of the shortcomings of classical approaches based on orthonormal bases. More specifically, we show why these redundant dictionaries provide an interesting alternative for image representation. We then introduce a special dictionary of 2-D ...
متن کاملLow-rate image retrieval with tree histogram coding
To perform image retrieval using a mobile device equipped with a camera, the mobile captures an image, transmits data wirelessly to a server, and the server replies with the associated database image information. Query data compression is crucial for low-latency retrieval over a wireless network. For fast retrieval from large databases, Scalable Vocabulary Trees (SVT) are commonly employed. In ...
