Some embodiments are directed to an integrated circuit and computer-implemented method for estimating a depth map from an image using a joint bilateral filter at reduced computational complexity. For that purpose, image data of an image is accessed as well as depth data of a template depth map. A joint bilateral filter is then applied to the template depth map using the image data as a range term in the joint bilateral filter, thereby obtaining an image-adapted depth map as output. The applying of the joint bilateral filter includes initializing a sum-of-weighted-depths volume and a sum-of-weights volume as respective empty data structures in a memory, performing a splatting operation to fill said volumes, performing a slicing operation to obtain an image-adapted depth volume, and performing an interpolation operation to obtain an image-adapted depth value of the image-adapted depth map for each pixel in the image.

Efficient implementation of joint bilateral filter

A system-on-chip is provided which is configured for real-time depth estimation of video data. The system-on-chip includes a monoscopic depth estimator configured to perform monoscopic depth estimation from monoscopic-type video data, and a stereoscopic depth estimator configured to perform stereoscopic depth estimation from stereoscopic-type video data. The system-on-chip is reconfigurable to perform either the monoscopic depth estimation or the stereoscopic depth estimation on the basis of configuration data defining a selected depth estimation mode. Both depth estimators include shared circuits which are instantiated in hardware and reconfigurable to account for differences in the functionality of the circuit in each depth estimator.

A device for motion estimation in video image data is provided. The device comprises a motion estimation unit () for estimating a current motion vector for an area of a current image by determining a set of temporal and/or spatial candidate motion vectors and selecting a best motion vector from the set of candidate motion vectors. The motion estimation unit () is further adapted for substantially doubling one or more of the candidate motion vectors and for including the one or more substantially doubled candidate motion vectors in the set of candidate motion vectors.

A method of processing video signals containing multiple images. The method comprises dividing a first image into regions and associating a first plurality of regions of the first image with a first image layer and a second plurality of regions of the first image with a second image layer. Motion estimation is performed on pixel values that are derived from pixel values associated with the first image layer, substantially in isolation from pixel values associated with the second image layer, to generate a first motion vector field, and the first motion vector field is used to perform motion-compensated processing on pixel values that are derived from pixel values associated with the first image layer. The result of the motion-compensated processing is combined with pixel values that are derived from pixel values associated with the second image layer to generate an output image.

The method reduces the time some items stay in the cache, and thereby improves the utilization of the cache for some applications, especially for video applications. The method comprises determining that each one of the multiple data elements has been updated through at least one write request; marking the data element set as a write-back candidate, in dependency on said determination; and writing the write-back candidate to the memory.

Various exemplary embodiments relate to a method and related motion estimation unit for performing motion estimation on video data comprising a plurality of frames. The method may begin by reading a current frame of the plurality of frames from a memory of a motion estimation unit. The method may then select a motion vector for each respective block of pixels in a current row of the current frame. The step of selecting the motion vector may include, for each respective block, selecting, by the motion estimation unit, a candidate vector for at least one block directly surrounding the respective block based on a determination of whether the directly surrounding block has been processed for the current frame, calculating, for each candidate vector, a difference value, and selecting, as the motion vector, the candidate vector with the lowest difference value.

The search area is defined to have its center offset from a center of the image segment. The offset may be determined by a global motion parameter.
