摘要： Aspects of the present invention are related to low complexity systems and methods for nonlinear diffusion filtering of a motion-vector field. Local weights in the nonlinear diffusion filter may be data-adaptive, and, according to one aspect of the present invention, may be determined such that spatial coherency may not be enforced at object boundaries although the object boundaries have not been explicitly detected. Thus, the methods and systems of the present invention may smooth a motion-vector field without smoothing the motion-vector field across an object boundary. According to a second aspect of the present invention, motion vectors with a low confidence value may be suppressed, while motion vectors with a high confidence value may be propagated. According to another aspect of the present invention, motion estimation methods and systems may incorporate the methods and systems of the nonlinear diffusion filtering according to the present invention.

摘要： Systems, devices and methods are described for performing hierarchical motion estimation by downsampling a current frame to generate a downsampled current frame, specifying a downsampled block in the downsampled current frame, where the downsampled block corresponds to a block of the current frame, and specifying a source block associated with the downsampled block, where the source block is larger than the downsampled block. Motion estimation may then be performed in a downsampled reference frame using the source block.

摘要： Sub-sampling pattern design for motion estimation in video compression. A motion estimation method divides a first frame into a plurality of macroblocks, performs block matching for a current macroblock pair on a candidate macroblock pair of a second frame. The current macroblock pair and the candidate macroblock pair are sampled according to a sub-sampling pattern, and an error measure between the current and candidate macroblock pairs is calculated. The sub-sampling pattern is constructed by a plurality of repeating units, and each repeating unit is composed of a first and a second pattern unit.

摘要： A video coding device may be configured to code a bitstream including multiple views plus depth information. Two of the views may have reduced resolutions, while a third view may have a full resolution. The third view may be predicted relative to upsampled versions of the two reduced-resolution views. Each view may include texture data and depth data, such that a view component may include a texture component and a depth component. Moreover, the texture and depth components may be arranged within an access unit according to a particular order, which may simplify component extraction from the access unit.

摘要： Adaptive control can use hierarchical motion estimation (HME) and/or multiple reference motion estimation (MRME) for the motion estimation of current encoding blocks. Both HME and MRME are allowed in the motion estimation to achieve a high coding gain. Control consists of slice level control and macro-block (MB) level control. A slice is one or more contiguous macroblocks. In slice level control, it is decided to use only one reference frame or use multiple reference frames to coding current slice based on the motion vectors obtained in coarse level motion estimation. In MB level control, it is decided to perform MRME or perform HME for the MB and its subblocks based on the coarse level motion vectors of the MB.

摘要： A clustering unit obtains a distance between a local motion vector obtained per block of a predetermined size and a representative motion vector for each of clusters stored in a delay buffer, classifies the local motion vector into a cluster to which the motion vector having the shortest distance belongs, and outputs the information of the classified clusters and the local motion vectors. Average value calculation units accumulate an average motion vector by accumulating the local motion vectors of the respective clusters, and output the average motion vector as a motion vector representing the cluster. A global motion vector determination unit outputs the motion vector having the largest number of elements in its cluster among the motion vectors representing the clusters as the global motion vector. The present technology may be applied an image processing device.
