In some examples, a system may receive, from at least one camera of a vehicle, at least one image including a road. The system may further receive vehicle location information including an indication of a location of the vehicle. In addition, the system may receive at least one of historical information from a historical database, or road anomaly information, where the road anomaly information is determined from at least one of a road anomaly database or real-time road anomaly detection. Based on the at least one image, the indication of the location of the vehicle, and the at least one of the historical information or the road anomaly information, the system may generate at least one of a disparity map or a disparity image.

A gaze point acquisition section 470 in a compression coding section 422 of a server 400 acquires position information associated with a gaze point of a user in a moving image that is generated by an image forming section 420 and is displayed on a client. An attention degree estimation section 472 estimates an attention degree on the basis of a position of the gaze point, for each of unit regions produced by dividing a frame plane. A compression coding processing section 474 compression-codes the moving image at a compression rate varied in the frame plane according to a distribution of the attention degrees. A communication section 426 transmits compression-coded data to an image processing apparatus 200.

Systems and methods for streaming and playing back video having a variety of resolutions, frame rates, and/or sample aspect ratios, where the video streams are encoded at one of a number of maximum bit rate levels, in accordance with embodiments of the invention are disclosed. One embodiment includes a processor, and storage containing data relating combinations of resolution and frame rates to maximum bitrates, where a plurality of resolution and frame rates that are related to the same maximum bitrate form a maximum bitrate level. In addition, an encoding application configures the processor to encode a video stream as a plurality of video streams having different resolutions and frame rates, where the target maximum bitrate used during the encoding is selected based upon the maximum bitrate levels of the resolution and frame rate combinations indicated within the data relating combinations of resolution and frame rates to maximum bitrates.

The present disclosure provides a communication control system and a communication control method capable of appropriately modifying an image compression algorithm when transmitting an I/O signal and an image signal through the same transmission line. In a communication control system that transmits image frame data and I/O data through the same transmission line from a first communication device to a second communication device, a transmission history of image frame data and I/O data and a reception history of ACK for the image frame data and ACK for the I/O data are managed. ACK receiving time and bandwidth utilization are calculated for each of the image frame data and the I/O data from the transmission history and the reception history.

To transmit image frame data appropriately according to the utilization rate of a receiving buffer and prevent the overflow of the receiving buffer, a communication control system transmits image frame data from a first communication device-to a second communication device. The second communication device includes a receiving buffer that receives image frame data from the first communication device, and a return unit that returns an ACK frame to the first communication device at timing reflecting a utilization rate of the receiving buffer. The first communication device includes an estimation unit that receives the ACK frame from the return unit of the second communication device and estimates the utilization rate of the receiving buffer from receiving time of the ACK frame, and a modification unit that modifies an image compression algorithm of the image frame data based on the estimated utilization rate of the receiving buffer.

A video processing method is disclosed to include: generating one or more initial predictions for a sub-block of a current video block of the video; refining the one or more initial predictions to generate a final prediction block using a prediction refinement with optical flow (PROF) procedure by calculating motion vector differences based on variables having a bit width not exceeding a predetermined maximum bit width; and performing a conversion between the current video block and a coded representation of the video using the variables having the bit width not exceeding the predetermined maximum bit width.

The present disclosure is directed toward systems and methods for optimizing video conferences. For instance, systems and methods described herein optimize both the transmission and display of one or more video conference data streams. Systems and methods described herein optimize the transmission and display of one or more video conference data streams by identifying a context associated with the one or more video conference data streams and optimizing the one or more video conference data streams based on the identified context.

The present technology relates to an image processing device and an image processing method capable of obtaining tile images of an appropriate image size. An image processing unit sets an image size of tile images, which form a grid image and are stored in a high efficiency image file format (HEIF) file, according to a target image size or a target bit rate of the tile images, and generates the tile images of the image size. The present technology can be applied to, for example, a digital camera or the like that generates an HEIF file in which tile images are stored.
