The execution order of the main components in a JPEG2000 encoder, i.e. the coding sequence, plays a significant role in its performance, implementation cost and memory requirement. The coding sequence is mainly affected by the bit allocation strategy. Existing strategies either require a large working memory or can not be used in rate constrained applications. In this paper, an improved pre-compression...
In advanced multimedia applications coded video signals are often transmitted over error prone channels. Lossy video coding together with channel errors causes more degradation in quality of the video. Unequal Error Protection (UEP) is one way to address this issue. The efficiency of UEP can be improved by carefully considering the importance of each protected element. Using UEP with scalable video...
Today, advanced multimedia services such as video conferencing and video streaming are widely used. In these applications, coded video signals are transmitted over error prone channels. Lossy source coding together with channel errors cause more degradation in the quality of received video. Hence, many error control techniques have been developed in the last ten years. Unequal error protection (UEP)...
Four back-propagation training method for an offline neural network is compared in this paper. The neural network is designed to estimate the speed of an induction motor in a sensorless vector control system. In first step, four different training algorithms are used to train the neural network. Each training algorithm is tested with up to 35 neurons with fixed number of training iterations. The number...
