Aiming to target occlusion problem in complex scenes, human action recognition via a top-view vision is proposed. However, in this view, the human behavior rotated will be mistakenly identified as another behavior. To address this situation, taking into account the rotation invariance of the moments, human static posture are represented by Hu moments, and using the SVM as trainer and classifier. According...
Particle filter algorithm is poor at consistently maintaining the multi-modality problem and remains particle degeneracy phenomenon. This shortcoming can be addressed through using Mixture Particle Filter (MPF) to model the target distribution as a non-parametric mixture model. According to computational complexity of the particle filter algorithm, Gaussian Particle Filter (GPF) is used. The particle...
