Transcoding techniques require a high complexity and reduce the video quality with every transcoding step. When transcoding an input bitstream to scalable video coding (SVC), only one adaptation step is required and a scaled bitstream is extractable afterwards. To reduce the H.264/AVC-to-SVC transcoding complexity, we propose a transcoding architecture which combines optimized closed- and open-loop transcoding techniques. This transcoder scales the complexity depending on the available resources. Relative to a cascaded decoder-encoder the complexity can be reduced by 99.28%, while a high rate distortion efficiency is maintained and a high degree of scalability guaranteed.

Objective picture quality measures cannot estimate the effect of blocking artifacts caused by video compression sufficiently. In this paper, we apply cepstrum analysis to quantify the blocking artifacts. We show experimental results for some test sequences using different coding schemes and prove effectiveness of our approach.

Development of Wireless EEG system is described. Realtime impedance monitoring and active electrodes are introduced in order to reduce noise from impedance changes caused due to body motion, and to prevent noise from power line interference, respectively. EEG ASICs are developed for the system. The complete system has a low noise (60nV/√Hz) and is packaged in a compact enclosure (38mm × 38mm × 16mm). The system is evaluated against different types of artefacts and possible applications with the system are discussed.

Max pooling has been regard as the best pooling method in image classification when image features are coded by sparse coding [2]. However, max pooling reduces the classification discrimination, since it doesn't distinguish the sign of coding coefficient but only selects the max absolute value. In order to increase the image representation discrimination, we preserve the sign of code coefficient and develop a feature pooling method named PN-Max pooling. Experimental results show that PN-Max pooling achieves higher image classification accuracy than Max pooling.

Mobile 3D graphics use tile-based rendering algorithm in order to lower power consumption. For rendering tile by tile in the tile-based rendering, tile-binning process is inevitable and has to store the results of geometry processing into scene buffer, which causes memory access severely. Several methods were proposed to reduce memory bandwidth for tile-binning process. However, these memory-bandwidth reduction methods require more computations. Hsieh et al. attempted to eliminate edges in order to decrease the number of overlap test. Their method could only eliminate 0.02% of edges because the edges parallel to the axes can be eliminated. In this study, we propose a simple method to reduce the number of the overlap test by detecting 1D-tile overlapped primitives, which are overlapped with only one-dimensional tiles while keeping low memory bandwidth.

The minimum usable received signal power depends on the robustness to undesired signals by deployed receivers. Tests of 26 NTIA approved "converter boxes" show that these are subject to de-sensitization by a signal offset from the desired signal by 1 to 15 channels.
