Abstract:
Importance prioritised coding is a principle aimed at improving the interpretability (or image content recognition) versus bit-rate performance of image coding systems. This can be achieved by (1) detecting and tracking image content or regions of interest (ROI) that are crucial to the interpretation of an image, and (2)compressing them in such a manner that enables ROIs to be encoded with higher fidelity and prioritised for dissemination or transmission. Traditional image coding systems prioritise image data according to an objective measure of distortion and this measure does not correlate w

Abstract:
Image sizes have increased exponentially in recent years. The resulting high-resolution images are often viewed via remote image browsing. Zooming and panning are desirable features in this context, which result in disparate spatial regions of an image being displayed at a variety of ( spatial) resolutions. When an image is displayed at a reduced resolution, the quantization step sizes needed for visually lossless quality generally increase. This paper investigates the quantization step sizes needed for visually lossless display as a function of resolution, and proposes a method that effective

The research focuses on three image coding standards: JPEG, JPEG2000, and MPEG-4 Visual Texture Coding (VTC). JPEG is a well-known and matured standard. It has been widely used for natural image compression, especially very popular for digital still camera applications. In the first part of this dissertation, we proposed fully pipelined JPEG encoder and decoder for high speed image pr

The two key technologies of JPEG 2000 are Discrete Wavelet Transform (DWT) and Embedded block coding with optimized truncation (EBCOT). DWT can decompose the signals into different sub-bands with both time and frequency information and facilitate to achieve high compression ratio. Embedded block coding with optimized truncation (EBCOT) is another important technology in JPEG 2000. It

In this Thesis, we discuss the basic architecture of JPEG-2000 system, which could be viewed as an evolution of image compression techniques during recent years. While over the past decades, a different class of image coding schemes, generally referred to as second-generation image coding technique, has been proposed, telling us that edges have features more rich in information used for recognition or perceiving an image. Derived from this concept, we propose two methods to combine the JPEG-2

However, if transmitting images thought the noisy channel and the markers check to be wrong, the images won’t reconstruct. So the algorithm partitions the wavelet coefficients into several groups, and use JPEG 2000 to compress these groups. Each group is delivered over noisy channel to disperse risk. After that, this algorithm can improve the probability of image reconstructed by decoder, and it can save t

The JPEG 2000 provides the numerous advantages over the existing JPEG standard. Performance gains include improved compression efficiency at low bit rates or for large images, while new functionalities include, progressive transmission, lossy or lossless compression, and region-of-interest (ROI).

For entropy-coded JPEG-2000 images, a transmission error in a codeword (subband sample) may cause the underlining codeword (subband sample) and its subsequent codewords (subband samples) to be misinterpreted, resulting in a great degradation of the received images. Here a transmission error may be a single-bit error or a burst error containing N successive error bits. The objective of the proposed approach is to detect and conceal transmission errors in
