Neural Network-Based Reference Block Quality Enhancement for Motion Compensation Prediction

Neural network based image coding quality prediction

Current developments in digital image coding tend to involve more and more complex algorithms, and require therefore an increasing amount of computation. To improve the overall system performance, some schemes apply a different coding algorithms to separate parts of an image according to the content of this subimage. Such schemes are referred to as dynamic coding schemes. Applying the best suit...

Impact of Reference Distance for Motion Compensation Prediction on Video Quality

Transmitting high-quality, real-time interactive video over lossy networks is challenging because data loss due to the network can severely degrade video quality. A promising feedback technique for low-latency video repair is Reference Picture Selection (RPS), whereby the encoder selects one of several previous frames as a reference frame for predictive encoding of subsequent frames. RPS can op...

Analysis on Prediction Efficiency of Overlapped Block Motion Compensation

We theoretically evaluate the prediction efficiency of the overlapped block motion compensation (OBMC) compared with the conventional non-overlapped approach. Based on the one-dimensional signal model characterized by the AR(1) process and first-order polynomial motion, a condition under which the performance of the OBMC is better, and an optimum window function are derived. From the results, w...

Nanofluid Thermal Conductivity Prediction Model Based on Artificial Neural Network

Heat transfer fluids have inherently low thermal conductivity that greatly limits the heat exchange efficiency. While the effectiveness of extending surfaces and redesigning heat exchange equipments to increase the heat transfer rate has reached a limit, many research activities have been carried out attempting to improve the thermal transport properties of the fluids by adding more thermally c...
