Survey Of Ship Detection In Video Surveillance Based On Shallow Machine Learning, Zhenbo Bi, Shiyou Zhang, Yang Hua, Yuanhong Wu
Journal of System Simulation
Abstract: At present, detection of ship targets in video surveillance based on shallow machine learning methods is still attracting attention in the fields of underwater cultural heritage protection, marine aquaculture, maritime traffic, and port management. This paper provides a review and discussion for this kind of ship detection methods. The ship target detection based on video surveillance is divided into five parts according to the key technologies involved: preprocessing, region of interest extraction, target segmentation, ship feature extraction and ship type recognition. According to different functional modules, the core problems involved in them are pointed out, and the core ideas, …

Study On Irregular Projection Surface Depth Perception Geometric Correction, Baoxing Bai, Yang Fan, Han Cheng, Zhang Chao
Journal of System Simulation
Abstract: In order to improve the universality of the projector projection scene, a method of depth perception geometric correction on the irregular projection surface was proposed. With the theoretical analysis of the coupling, the weaken coupling solution was proposed. The depth of the irregular projection surface could be acquired by the encoded color structured light. After that, the feedback was used to solve the maximum visual projection area, the dynamic slicing algorithm for the irregular surfaces depth information was used to pull away the stratification planes, so a corresponding homography matrix for each stratification plane was calculated and the homography …

Monocular Depth Image Mark-Less Pose Estimation Based On Feature Regression, Chen Ying, Shen Li
Journal of System Simulation
Abstract: Monocular camera mark-less pose estimation system suffers low accuracy, robustness and efficiency due to variety of action, self-occlusion of human body. A method of feature exaction from point clouds was proposed, in which a single-to-multiple (S2M) feature regressor and a joint position regressor were designed to quickly and accurately predict the 3D positions of body joints from a single depth image without any temporal information. Experiment result shows that the estimation accuracy is superior to that of state-of-the-arts and multi-camera based methods.
