摘要： A method is disclosed for detecting and locating players in soccer video frames without errors caused by artifacts by a shape analysis-based approach to identify the players and the ball from roughly extracted foregrounds obtained by color segmentation and connected component analysis, by performing a Euclidean distance transform to extract skeletons for every foreground blob, by performing a shape analysis to remove false alarms (non-players and non-ball), and then by performing skeleton pruning and a reverse Euclidean distance transform to cut-off the artifacts primarily caused by playing field lines.

摘要： According to an implementation, a set of particles is provided for use in estimating a location of a state of a dynamic system (1010). A local-mode seeking mechanism is applied to move one or more particles in the set of particles (1020), and the number of particles in the set of particles is modified (1030). The location of the state of the dynamic system is estimated using particles in the set of particles (1040). Another implementation provides dynamic state estimation using a particle filter (565) for which the particle locations are modified using a local-mode seeking algorithm based on a mean-shift analysis (610) and for which the number of particles is adjusted using a Kullback-Leibler-distance sampling process (830-860). The mean-shift analysis may reduce degeneracy in the particles, and the sampling process may reduce the computational complexity of the particle filter. The implementation may be useful with non-linear and non-Gaussian systems.

The location is estimated using a particle-based framework, such as a particle filter. It is determined that the estimated location for the object in the particular image is occluded. A trajectory is estimated for the object based on one or more previous locations of the object in one or more previous images in the sequence of images. The estimated location of the object is changed based on the estimated trajectory.

摘要： Substantial elimination of errors in the detection and location of overlapping human objects in an image of a playfield is achieved, in accordance with at least one aspect of the invention, by performing a predominately shape-based analysis of one or more characteristics obtained from a specified portion of the candidate non-playfield object, by positioning a human object model substantially over the specified portion of the candidate non-playfield object in accordance with information based at least in part on information from the shape-based analysis, and removing an overlapping human object from the portion of the candidate non-playfield object identified by the human object model. In one exemplary embodiment, the human object model is an ellipse whose major and minor axes are variable in relation to one or more characteristics identified from the specified portion of the candidate non-playfield object.

摘要： Various implementations are described. Several implementations relate to depth-image-based rendering. Many of these implementations use temporal information in synthesizing an image. For example, temporal information may be used to generate a background layer for a warped image, and then the background layer may be blended with the main layer. One method includes accessing information from a reference image (1005). The reference image is for a reference view at a particular time. Information from a second image is accessed (1010). The second image is for a different time than the particular time. An additional image is created based on the information from the reference image and on the information from the second image (1015). The additional image is for an additional view that is different from the reference view and being for the particular time.
