Various motion input and sensing methods have been evaluated in designing a home-based physiotherapy rehabilitation system for spinal cord injury patients. The important design factors include; the ability of the system to track human motion such that the requirements of a game input and data logging software are met; the ability to modify the platform to suit the existing and possible future requirements;...
We propose a new DCT-based energy function EDCT for object-oriented segmentation and compression. By minimizing EDCT the best possible split of the image blocks can be found which leads to better segmentation and compression. Consistent motion vectors can be obtained by using an extended 3D energy function, in the spatio-temporal domain, which measures block motion over multiple frames. Tests on images...
This paper illustrates two implementations of an algorithm for tracking the movements of small high contrast structures such as calcified coronary plaques over advancing temporal phases in cardiac CT. The algorithm is based on integrating concepts of image reconstruction and image segmentation. The essential difference between the two implementations of this algorithm is that the first uses the chord-based...
