With the increasing dominance of the transform coding technique virtually in every image and video coding schemes proposed up to date, e cient transform coding system implementation has become an important research topic. This thesis addresses two system issues that may arise in practice: (i) e cient architecture designs for the discrete wavelet transform; and (ii) e cient transform coding for ...

Early investigations of temporal coding in the gustatory system showed that the time course of responses in some neurons showed systematic differences across the various classes of taste stimuli, implying that the temporal characteristics of a response can convey information about a taste stimulus. Studies of temporal coding in the gustatory system have grappled with several unique methodologic...

This paper presents an error resilient H.263 video compression system over noisy channels. We develop a video segment regulation algorithm at the decoder to efficiently identify and correct erroneous start codes and block addresses. In addition, a parity-embedded error detection technique is also implemented to enhance the error detection capability of the decoder at the macroblock4ayer. After ...

In this paper, we propose a modification of the HDWTSVD algorithm to encode monochromatic images that combines DWT and SVD techniques. At the encoder side, the input image is divided into blocks (tiles) of 64x64 pixels. A criterion based on the average standard deviation of 8x8 subblocks is used to choose DWT or SVD. If the tile exhibits a high average standard deviation, it is compressed by us...

This paper presents a method of the scalable foveation image coding with a fuzzy system. Our objective is to maximize foveated wavelet image quality index (FWQI). With the foveated visual sensitivity model, image regions are first prioritized. The image regions closed to the foveation points have higher priorities than those, which are far away from the foveation points. The discrete wavelet tr...

Although previous studies of horses have investigated their facial expressions in specific contexts, e.g. pain, until now there has been no methodology available that documents all the possible facial movements of the horse and provides a way to record all potential facial configurations. This is essential for an objective description of horse facial expressions across a range of contexts that ...

Despite the remarkable achievements of modern communication systems based on Shannon’s theory, there is still considerable room for exploration in information transmission capacity, and semantic technology has emerged as a promising approach this regard. Nonetheless, benefits remain elusive, absence unified system model hindered practical implementation. In context, we contend that can benefit ...

Estimation of the channel and its performance under dynamic conditions have always remained a challenge for wireless communication domain. New techniques were developed for channel diversity and spectrum utilization. In this paper a new interference management with resource control is proposed, to achieve the objective of higher performance in MIMO systems, using interference conditions. A gene...
