    摘要: The present invention involves detecting dark noise artifacts in coded images and video. Locations of artifacts in compressed pictures are found. A strength of the artifact per block is determined as is an overall dark noise artifact strength for each picture. Artifact detection and strength assignment is performed by analyzing candidate areas that could be prone to this type of artifact. Multiple features such as block variance, color information, luminance levels and location of the artifact could be used in this process. Also, median filtering may be used on the identified areas to eliminate isolated areas. A final artifact parameter for each picture can be assessed based on the total number of blocks that are classified as dark noise and also the strength of each macroblock.

    摘要: A method and apparatus for detecting banding artifacts in digital images and video contents. The method operates to (i) find the locations of the banding artifacts, (ii) determine the strength of the banding artifact per block, and (iii) determine overall banding artifact strength per picture. The banding artifact detection and strength assignment is done by first finding areas that are prone to banding artifact and then considering the local characteristics of the area to reduce the false detection. The banding artifact strength of a picture is determined by considering the size and the strength of the artifact areas in this picture as well as the artifact strength in the neighboring pictures.

In one aspect, a device configured to obtain a RCC signal includes: a receiving circuit to receive an analog AM RCC signal and to process said analog AM RCC signal to generate a digital AM RCC signal; and a demodulation circuit in connection with said receiving circuit, to demodulate said digital AM RCC signal to generate the RCC signal. In another aspect, a method for obtaining a RCC signal includes: processing a received analog AM RCC signal to generate a digital AM RCC signal; and demodulating said digital AM RCC signal to generate said RCC signal. Since the digital processing method is more reliable than the analog processing method, the reliability of RCC signal reception and demodulation are improved.

    摘要: Adaptive motion information cost estimation is achieved in processing video information. A transmission cost is estimated that is associated with encoding a motion vector difference (mvd) in motion vectors that describe a motion characteristic of the video information. The mvd is encoded based on minimizing a rate estimation mismatch associated with the motion vectors. The encoding step includes computing a bit count associated with the mvd using CABAC. A value is indexed that corresponds to the cost from one or more entries in the lookup table. The cost relates to context or content characteristics associated with the video information. The lookup table is adaptively updated based on a change in the contextual information or content characteristics. The value is dynamically adjustable based on the change.

    摘要: Video compression is performed under multiple distortion constraints. Video coding includes determining a first set of Lagrangian cost values for multiple coding modes using a first distortion metric, determining a second set of Lagrangian cost values for the multiple coding modes using a second distortion metric, and selecting one of the coding modes based on the first set of Lagrangian cost values and the second set of Lagrangian cost values to encode a pixel block using the selected coding mode. The distortion metrics can include information associated with video display characteristics such as screen display size, video processing performance, a distortion characteristic, a temporal characteristic, or a spatial characteristic. The distortion metrics can also include characteristics of multiple video displays, such as parameters for usage, importance, design, and the technology type of the video displays.
