A modified delta encoding method and its applications to speech signal are proposed. In this method, Hungarian algorithm is applied to find the minimum distance of arbitrary two frames in speech signal and minimum spanning tree is used to find an effective delta encoding path. In simulation, the method is applied to the compression of sinusoidal coding. The results show that the data size after compression...
Correct recognition of the lines is essential for technical drawing understanding. Automation solution is quite difficult due to the limitations of machine vision algorithm. In order to promote development of better technology, according to the fast and high-quality clustering algorithm particle swarm optimization (PSO), a new fast and high-quality line clustering algorithm present in this paper,...
We propose a depth assisted video object tracking algorithm that utilizes stereo vision technique to detect and handle various types of occlusions. The foreground objects are detected by using a depth and motion-based segmentation method. The occlusion detection error caused by inaccurate motion vectors is avoided by combining the depth segmentation results with the previous occlusion status of each...
