摘要： Innovations in encoder-side decisions that use the results of hash-based block matching are presented. For example, some of the innovations relate to ways of building hash tables that include some (but not all) uniform blocks. Other innovations relate to ways of determining motion vector resolution based on results of hash-based block matching. Still other innovations relate to scene change detection, including long-term reference picture selection and picture quality determination during encoding.

摘要： An image processing apparatus includes an image processor and an encoder. The image processor enhances an edge of an input image, removes noise from the input image, synthesizes the edge-enhanced image and the noise-removed image, and removes a high frequency from the synthesized image. The encoder pre-encodes a downsized synthesized image, obtains a pre-bit rate of the pre-encoded image, sets a quantization parameter value based on a reference bit rate and the pre-bit rate, and compresses the high-frequency removed image based on the quantization parameter value.

摘要： A method for enhancing visual data when communicating visual data over a network from a first node to a second node. The method at the first node comprises developing at least one modified hierarchical algorithm from a known hierarchical algorithm operable to substantially recreate at least one section of higher-quality visual data. References to one or more known hierarchical algorithms from which the modified hierarchical algorithms were developed are transmitted to the second node along with one or more modifications to the one or more known hierarchical algorithms operable to reproduce the one or more modified hierarchical algorithms from the known hierarchical algorithms. The second node is able to recreate substantially the higher-quality video using the modified hierarchical algorithm.

摘要： A system and method are disclosed for transcoding a video clip. In one implementation, a computer system determines N frames at which to divide a video clip into N+1 consecutive chunks, where N is a positive integer, and where the frames are determined based on the image content of the video clip, a minimum chunk size, and a maximum chunk size. Each of the N+1 chunks is provided to a respective processor for transcoding, and a transcoded video clip is generated from the transcoded N+1 chunks.

摘要： Methods and systems for storing and accessing dental images. The system includes an imaging system for acquiring x-ray projection frames. The imaging system is connected to a local server through a local area network. A cloud server communicates with devices on the local area. The x-ray projection frames are transmitted from the imaging system to the local server. The local server stores the series of related x-ray projection frames according to a specified policy. In one embodiment, the x-ray projection frames are compressed into a compressed image data set using a modified video compression prediction algorithm customized for x-ray images. The x-ray image data (whether compressed or not) is transmitted to the cloud server for storage. The x-ray image data can be accessed from the cloud server by external devices and by other local area networks.
