This article uses the original weld images as the research object. The OpenCV library is used in developing the weld image edge detection algorithm as the basic function library. Our research use gray transform filter as the pre-processing. The Canny operator is used as the edge detector to detecting the weld edge, and the Hough transform algorithm is used to detecting the welding line. Line location...
This paper explains and implements a fast image mosaic algorithm for unmanned aerial vehicle (UAV) sequence images. In this algorithm, feature points between images are matched using a modified Harris corner detection algorithm, and then an improved pyramid Lucas-Kanade optical flow algorithm and corner points matching authentication algorithm is used to achieve an effective match of the feature points...
The authors present a data-driven algorithm for interactive 3D human-character posing. They formulate the problem in a maximum a posteriori (MAP) framework by combining the user's inputs with the priors embedded in prerecorded human poses. Maximizing the posterior probability lets them generate a most-likely human pose that satisfies the user constraints. The system can learn priors from a huge, heterogeneous...
