Abstract: A HDR tone mapping system includes several modules. A semantic segmentation module is used to extract semantic information from the input image. An image decomposition module is used to decompose the input image to a high-bit base layer and a detail layer. A statistics module is used to generate statistics of pixels of the input image according to the semantic information. A curve computation module is used to generate a tone curve from the statistics. A compression module is used to compress the high-bit base layer to a low-bit base layer according to the tone curve, the statistics and the semantic information. A detail adjustment module is used to tune the detail layer according to the semantic information and the statistics to generate an adjusted detail layer. An image reconstruction module is used to combine the adjusted detail layer and the low-bit base layer to generate an output image.

Abstract: A system, method, and computer program product are provided for reducing GPU load by programmatically controlling shading rates in computer graphics. GPU load may be reduced by applying different shading rates to different screen regions. By reading the depth buffer of previous frames and performing image processing, thresholds may be calculated that control the shading rates. The approach may be run on any platform that supports VRS hardware and primitive- or image-based VRS. The approach may be applied on a graphics driver installed on a client device, in a firmware layer between hardware and a driver, in a software layer between a driver and an application, or in hardware on the client device. The approach is flexible and adaptable and calculates and sets the variable rate shading based on the graphics generated by an application without requiring the application developer to manually set variable rate shading.

Abstract: A method for performing automatic activation control regarding VRS and associated apparatus are provided. The method applicable to a processing circuit may include: utilizing a rendering classifier to intercept at least one set of original graphic commands on a command path to obtain at least one rendering property, for classifying rendering corresponding to the at least one set of original graphic commands; utilizing the rendering classifier to classify the rendering into at least one predetermined rendering type among multiple predetermined rendering types according to the at least one rendering property, in order to determine at least one shading rate corresponding to the at least one predetermined rendering type for the rendering; and utilizing a shading rate controller to control the processing circuit to selectively activate a VRS function of the processing circuit, for rendering at the at least one shading rate corresponding to the at least one predetermined rendering type.

Abstract: Various solutions for measurement report enhancement with respect to user equipment and network apparatus in mobile communications are described. An apparatus may initiate a voice or video call with a network node. The apparatus may determine whether Single Radio Voice Call Continuity before alerting stage (bSRVCC) is supported by the network node. The apparatus may cancel a transmission of a measurement report to the network node before an alerting stage when the bSRVCC is not supported by the network node. The apparatus may perform the voice or video call with the network node.
