    摘要: A method for accurately measuring flicker, by first determining an original value based on a difference between pixel values in corresponding locations in a first picture and a second picture. Next, a reconstructed value is determined, based on a difference between pixel values in corresponding locations in a reconstruction from an encoding of the first picture and a reconstruction from an encoding of the second picture. Then, a determination is made to include a comparison value, which is determined on a difference between the reconstructed value and the original value, in a measurement of flicker between the first picture and the second picture.

    摘要: Various implementations for reducing artifacts such as, for example, I-frame flicker are proposed. Particular implementations produce a no-flicker reference in which a picture intended to be coded as an I-frame is, first, coded as a P-frame using a reference picture from the previous GOP. Thus, continuity with the previous GOP is provided. According to a general aspect, a source image is inter-coded to produce coded source data. The coded source data is decoded to produce a modified source. The modified source is intra-coded to produce coded modified-source data. The coded modified-source data is decoded to produce a reference image.

    摘要: The present invention relates to a full-reference (FR) objective method for assessing perceptual quality of decoded video frames in the presence of packet losses and coding artifacts. A method of assessing perceptual quality is provided. First, a value indicating an amount of distortion in a corresponding portion is accessed. Then, that value is classified as packet-loss distortion or coding-artifact distortion. Next, the classified value is modified to account for visibility differences of the human visual system, based on the classification, and then the modified values are combined for the multiple portions, to form a value indicating a total amount of distortion for the multiple portions.

    摘要: An encoding methodology for a video encoder encodes target light change (TLC) frames in order to improve the quality of the resulting decoded video. Backward prediction is applied instead of forward prediction to the frames that are detected as TLC frames. Additionally, the last frame of the TLC activity is forced to use only intra-coding modes.

    摘要: Technologies may provide for detecting, validating, or confirming the validity of a handwritten signature. A logic architecture may be employed to detect a digital handwritten signature and validation data associated with a signature event, and to send the signature and the validation data to a trusted server. The logic architecture may validate the digital handwritten signature based on the signature and the validation data. Additionally, the logic architecture may present the digital handwritten signature with a reference to confirm the validity of the signature. The reference may be associated with identifying information corresponding to the event to confirm the validity of the signature.

    摘要: A method and apparatus are provided for encoding with hypothetical reference decoder compliant bit allocation. The apparatus includes an encoder (100) for encoding image data for a picture in a resultant bitstream by controlling a bit allocation during the encoding of the image data responsive to satisfying requirements for a subsequent decoding of the bitstream. The requirements relate to preventing at least one of an underflow condition and an overflow condition in a buffer during the subsequent decoding of the bitstream.
