    摘要: An occlusion detection system and method include a decomposer configured to decompose an image into a set of hierarchical parts. A hierarchy of classifiers is employed to detect features in the image and the hierarchical parts. A logical operation is configured to logically combine a classification result from at least two of the classifiers to detect an occlusion state of the image.

    摘要: A person detection system includes a face detector configured to detect a face in an input video sequence, the face detector outputting a face keyframe to be stored if a face is detected; and a person detector configured to detect a person in the input video sequence if the face detector fails to detect a face, the person detector outputting a person keyframe to be stored, if a person is detected in the input video sequence.

    摘要: A method generates a stylized image of a scene including an object. A set of n input images are acquired of the scene with a camera. Each one of the n input images is illuminated by one of a set of n light sources mounted on a body of the camera at different positions from a center of projection of a lens of the camera. Ambient lighting can be used to illuminate one image. Features in the set of n input images are detected. The features include depth edges, intensity edges, and texture edges to determine qualitative depth relationships between the depth edges, the intensity edges and the texture edges. The set of n input images are then combined in an output image to enhance the detected features according to the qualitative relationships.
