Abstract: Content aware video resizing is described. In one example, edge detection is done on pixel values of video frames. The edges are compared and an energy is determined for lines of pixels of a second frame based on the comparison. The low energy lines are selected, and the frame is resized using the selected lines. The lines correspond to either rows or columns and the resizing may be done by adding or removing columns or by adding or removing rows.

Abstract: An apparatus and method for depth retargeting in a virtual reality (VR) system color buffer compression. For example, one embodiment of a method comprises: dividing a virtual screen region into a plurality of smaller regions based on characteristics of a target screen; performing depth retargeting individually for each of the smaller regions including identifying a first set of the smaller regions on which to employ a first depth retargeting technique and a second set of the smaller regions on which to employ a second depth retargeting technique; wherein the first depth retargeting technique comprises subdividing one or more of the smaller regions from the first set into a plurality of sub-regions and performing depth retargeting individually on the sub-regions; combining results of the first depth retargeting technique and the second depth retargeting technique to render the virtual screen region.
