The recently approved digital still image standard known as JPEG2000 promises to be an excellent image and video format for use with a large range of applications. For adoption of the standard to take place in the consumer marketplace, implementations supporting real-time encoding and decoding of popular image and video formats must be created. It is a well-known fact that the major bottleneck of a JPEG2000 system is the bit/context modeling and arithmetic coding tasks (also known as tier-1 coding). This paper discusses a hardware implementation of a tier-1 coder that exploits available parallelisms. The proposed technique described in this paper is approximately 50% faster than the best technique described in the literature(1).

This paper presents a new approach to color image denoising under consideration of human visual system (HVS) model. The denosing process takes place in the wavelet transform domain. A contrast sensitivity function (CSF) implementation is employed into wavelet-based algorithm based on an invariant single factor weighting per subband and noise masking in succession. Experimental results show that the new approach is good in terms of perceptual error metrics and visual effect.

In this paper, we propose a new method for removing coding artifacts appeared in JPEG 2000 coded images. The proposed method uses a fuzzy control model to control the weighting function for different image edges according to the gradient of pixels and membership functions. Regularized post-processing approach and recursive line algorithm are described in this paper. Experimental results demonstrate that the proposed algorithm can significantly improve image quality in terms of objective and subjective evaluation.

This paper presents a new method to measure the quality of compressed images. The method is based on a Human visual System model and extracts perceptual structural information from images. This model is implemented and perceptual representations of images are built. These representations describe the structural information of images. For quality assessment, the representation of the original image, actually a reduced reference, is compared to the representation of the distorted image using similarity measures. Similarity scores have shown to be highly correlated with the quality of images produced by human observers in experiments. So the novelty of this method is that structural information is used to assess the quality. This method has been implemented in an application called "Smart Compress" (freely available on the Internet) which allows the user to compress images in JPEG format by choosing the visual quality of the output images.

In the present paper, we study the spatialization of the sound field in a room, in particular the evolution of room impulse responses as function of their spatial positions. The presented technique allows us to completely characterize the sound field in any arbitrary location if the sound field is known in a certain finite number of positions. Our technique simply starts from the measurements of impulse responses in a finite number of positions and with this information the total sound field can be recreated. An analytical solution of the problem is given for any rectangular room. Further, we determine the number and the spacing between the microphones needed to perfectly reconstruct the sound field up to a certain temporal frequency.
