Abstract
An example device for image processing includes a memory and one or more processors coupled to the memory and configured to determine a region of interest (ROI) within a first frame and a second frame of a plurality of frames, apply a first amount of filtering on the ROI of the first frame and the second frame to generate a filtered ROI, apply a second amount of filtering on a remaining region of the first frame and the second frame to generate a filtered remaining region, combine the filtered ROI and the filtered remaining region to generate a filtered frame, and output the filtered frame.
Claims24
A device for image processing, the device comprising:
- a memory;
- and
- one or more processors coupled to the memory and configured to:
- determine respective region of interests (ROIs) and respective remaining regions within a plurality of frames including a first frame and a second frame;
- apply a first amount of filtering on the ROIs to generate a filtered ROI, wherein to apply the first amount of filtering, the one or more processors are configured to determine a first group of frames from the plurality of frames to be included in filtering the ROIs based at least on a difference between an ROI in the first frame and an ROI in the second frame;
- apply a second amount of filtering on the remaining regions to generate a filtered remaining region, wherein to apply the second amount of filtering, the one or more processors are configured to determine a second group of frames from the plurality of frames to be included in filtering the remaining regions based at least on a difference between a remaining region in the first frame and a remaining region in the second frame;
- combine the filtered ROI and the filtered remaining region to generate a filtered frame;
- and
- output the filtered frame.

A computer-readable storage medium storing instructions thereon that when executed cause one or more processors to:
- determine respective region of interests (ROIs) and respective remaining region within a plurality of frames including a first frame and a second frame;
- apply a first amount of filtering on the ROIs to generate a filtered ROI, wherein the instructions that cause the one or more processors to apply the first amount of filtering comprise instructions that cause the one or more processors to determine a first group of frame from the plurality of frames to be included in filtering the ROIs based at least on a difference between an ROI in the first frame and an ROI in the second frame;
- apply a second amount of filtering on the remaining regions to generate a filtered remaining region, wherein the instructions that cause the one or more processors to apply the second amount of filtering comprise instructions that cause the one or more processors to determine a second group of frames from the plurality of frames to be included in filtering the remaining regions based at least on a difference between a remaining region in the first frame and a remaining region in the second frame;
- combine the filtered ROI and the filtered remaining region to generate a filtered frame;
- and
- output the filtered frame.
