摘要： Methods, systems, and apparatus are presented for reducing distortion in an image, such as a video image. A video image can be captured by an image capture device, e.g. during a video conferencing session. Distortion correction processing, such as the application of one or more warping techniques, can be applied to the captured image to produce a distortion corrected image, which can be transmitted to one or more participants. The warping techniques can be performed in accordance with one or more warp parameters specifying a transformation of the captured image. Further, the warp parameters can be generated in accordance with an orientation of the image capture device, which can be determined based on sensor data or can be a fixed value. Additionally or alternatively, the warp parameters can be determined in accordance with a reference image or model to which the captured image should be warped.

摘要： A rate control system is disclosed for video coding applications. The rate controller assigns a quantization parameter for video data in a picture in response to complexity indicators indicative of spatial complexity, motion complexity and/or bits per pel of the picture. A virtual buffer based quantizer parameter is proposed based on a virtual buffer fullness analysis and a target rate estimate, which is derived from the complexity indicators. A second quantizer parameter is proposed from a linear regression analysis of quantizer parameters used to code previously coded pictures of similar type (e.g., I pictures, P pictures or B pictures). A coding policy decision unit defines a final quantizer parameter from a comparison of the two proposed quantizer parameters.

摘要： Systems, apparatuses and methods whereby a base coded video signal is provided to a decoder having a set of post-processing stages. The base coded video signal can be decoded to produce a base decoded video signal. Post-processing of the base decoded video signal can be used to produce an enhanced quality video output signal. Application of a post-processing stage can be implemented according to the capabilities of the decoder and/or the instantaneous operating parameters of the decoder and/or characteristics of a display. A control signal, communicated over a dedicated channel separate from the base coded video signal, can be used initiate and/or aid implementation of a post-processing stage. The control signal can also provide information to assist/manage the decoding of the base coded video signal. The use of additional post-processing stages increases the complexity of an overall decoding process while improving the quality of a resulting reproduced video sequence.
