This paper presents a novel intra prediction method for inter pictures (i.e. P pictures and B pictures), denominated enhanced intra prediction (EIP). The traditional intra prediction only uses the reconstructed pixels to the left and above to derive intra prediction blocks. While the proposed method combines the left-above and right-below pixels to strengthen the prediction efficiency of the intra...
Abnormal event detection plays an important role in video surveillance and smart camera systems. Existing methods in the literature are usually not object-aware, where different objects are not distinguished in processing. In this work, we propose an efficient object-aware anomaly detection scheme, specifically focusing on certain object categories, such as pedestrians. We first perform a block-based...
Increasing strong demand for smaller insulated transformers, an ultra-small transformer has been developed by adopting an insulated hybrid structure with the size of W16.5 × L19.5 × H10.5 mm⁁3, whose volume is 65 % smaller than conventional insulated transformers. Our new transformer has been improved in terms of noise reduction by 5–15 dB, power efficiency increase by 2 %, and production efficiency...
A new optimistic synchronization algorithm for Parallel Discrete Event Simulation (PDES) called Safe BTW is proposed in this paper. This new algorithm eliminates risky event processing in the Time Warp processing stage of the original BTW algorithm and is founded on a concept called "safe causal relation". In our new algorithm, the length of any chained rollback operations is limited to...
