In this paper, we propose a novel facial expression recognition method under partial occlusion based on Gabor multi-orientation features fusion and local Gabor binary pattern histogram sequence (LGBPHS). Firstly, the Gabor filter is adopted to extract multi-scale and multi-orientation features. Secondly, the Gabor magnitudes of different orientations in the same scale will be fused according to the...
An improved modular complete 2DPCA method was proposed. Firstly, the original images are divided into sub-images in proposed approach. The best projecting matrix from general matrix that is made up of all normalized sub-images could be obtained accordingly. Secondly, when all sub-images of training samples and testing samples were projected to the best projecting matrix, the recognition features was...
Real time traffic such as voice and video have strict requirements on the acceptable end-to-end packet delay. When there are different types of traffic with different requirements on tolerable latency, priority based packet scheduling schemes are normally used in order to reduce the queuing delay for real time services. However, in cognitive radio networks, the time that the system spends on spectrum...
