Abstract: A method includes obtaining, using at least one processor, an input image frame. The method also includes identifying, using the at least one processor, one or more regions of the input image frame containing redundant information. In addition, the method includes performing, using the at least one processor, an image processing task using the input image frame. The image processing task is guided based on the one or more identified regions of the input image frame. The method may further include obtaining, using the at least one processor, a coarse depth map associated with the input image frame. Performing the image processing task may include refining the coarse depth map to produce a refined depth map, where the refining of the coarse depth map is guided based on the one or more identified regions of the input image frame.

Abstract: Methods and systems for compressed domain progressive application of computer vision techniques. A method for decoding video data includes receiving a video stream that is encoded for multi-stage decoding. The method includes partially decoding the video stream by performing one or more stages of the multi-stage decoding. The method includes determining whether a decision for a computer vision system can be identified based on the partially decoded video stream. Additionally, the method includes generating the decision for the computer vision system based on decoding of the video stream. A system for encoding video data includes a processor configured to receive the video data from a camera, encode the video data received from the camera into a video stream for consumption by a computer vision system, and include metadata with the encoded video stream to indicate whether a decision for the computer vision system can be identified from the metadata.

Abstract: A method of controlling a link state of a communication port of a storage device according to the present inventive concepts includes setting the link state of the communication port to a link active state that can exchange data with a host, determining a holding time of a first standby state among link states of the communication port, changing the link state of the communication port to the first standby state, monitoring whether an exit event occurs during the holding time from the time when a transition to the first standby state occurs, and in response to an exit event not occurring during the holding time, changing the link state of the communication port to a second standby state. A recovery time from the first standby state to the link active state is shorter than a recovery time from the second standby state to the link active state.
