Face recognition has been widely used in many application areas such as photo album management and information security. Rapid growth of handheld devices and social networks bring new challenges to face recognition algorithm design and system engineering. To be effective on a handheld device, the face recognition model must be simple and lightweight, and also needs to handle the large variations in...
Octree decomposition has been proven to be one of the most successful approaches for progressive geometry compression of 3D models. An octree is built up by recursively subdividing the bounding box of 3D models into a number of sub-cells. Each node of the octree has an 8-bit-binary code called occupancy code, indicating the non-emptiness of its children, given a pre-defined traversal order. Then the...
Traditional 2D line-drawing methods are mostly manual and hence quite laborious. A new 3D-model-assisted approach makes archaeological reports more accurate, efficient, and informative. The Web extra is a video that shows a new computer-assisted archaeological line drawing approach and its application in the investigation of the Longmen Grottoes, a cultural heritage site in China.
