surf tracking
- Most motion-based tracking algorithms assume that objects undergo rigid motion, which is most likely disobeyed in real world. In this paper, we present a novel motion-based tracking framework which makes no such assumptions. Object is represented by

- 提出一种用于电子稳像技术改进的代表点匹配算法。通过合理的划分区域，保证在 域内各点运动的一致性，利用代表点匹配算法确定各区域内的运动矢量，并把其代入变换模型可得关于旋转、平移和变焦等信息的线性方程组，求其方程的解得全局运动矢量-Proposed for improved electronic image stabilization representative point matching algorithm. Through reasonable zoning, ensure the cons
Regional Cardiac Motion and Strain Estimation in Three-Dimensional Echocardiography: A Validation Study in Thick-Walled
- Automatic quantification of regional left ventricular deformation in volumetric ultrasound data remains challenging. Many methods have been proposed to extract myocardial motion, including techniques using block matching, phase-based correlation, dif
h264-master
- Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion is in three dimensions but the ima
