The WRGB-OLED with larger-sized display resolution can bring us more colorful and better visual experiences. However, it also makes OLED display system suffer from a serious bottleneck on memory bandwidth. In this paper, the lossless pixel-gradient EC algorithm is proposed to overcome this bottleneck. It consists of two core techniques: Finer-Gradient-Based Prediction (FGBP) and Gradient-Based Golomb-Rice...
To solve the problem of the neural network architecture design, a dynamic feedforward neural network architecture design method based on information entropy is proposed. In this method, the neural network's cost function is composed of the cross entropy of the neural network's expected output and actual output and Renyi's entropy of the hidden node's output. This does not require the learning samples...
In order to reduce the influence of illumination changes on the appearance of smart meter and improve the accuracy of smart meter appearance detection, based on the local two value algorithm theory, the algorithm is improved as the local two value algorithm of the rotation invariance. But rotation invariant local value operator with the sampling number of blocks increases the operator types will be...
This paper presents a view synthesis algorithm without depth cameras and camera calibration: First, use the left and right view sequence to obtain disparity estimation map. Then do twice horizontal synthesis with the initial disparity map and smoothing filtered disparity map on the left view sequence. Finally, merging the two composite image to finish hole filling. Simulation results show that the...
Many real-world optimization problems encounter the presence of uncertainties. Dynamic optimization is a class of problems whose fitness functions vary through time. For these problems, evolutionary algorithm is expected to adapt to the changing environments immediately and find the best solution accurately. Besides, most of the environmental changes may not be too drastic in real-world applications,...
Navigation in dynamic or unknown environment is a challenge for autonomous vehicles because of the limited range of sensors and not accurate maps. In this paper, we analyze three conditions on the unobserved and uncertainty environment during navigation. They are "known space", "free space", and "unknown space". For the dynamic environment, we derive an algorithm to correct...
The current concept semantic similarity calculation based on ontology does not take full advantage of the concept semantic information. In this paper we will present a new concept semantic similarity algorithm deviding the concept similarity into two parts: one is concept name similarity calculation, concept name degree and concept name edit distance calculation. The other is concept property similarity...
For developing a surgical simulation platform that not only accords with software design standards but also conforms with clinical professional requirements; proposed designing and developing surgical simulation platform using COM (Component Object Model) component technology. Surgical simulation platform based on COM designed three core module: model management; surgical planning; surgical evaluating;...
