Abstract: A method and system for of single view image 3D face synthesis. The method comprises the steps of a) extracting feature points from the single view image; b) transforming the feature points into 3D space; c) calculating radial basis function (RBF) parameters in 3D space based on the transformed feature points and corresponding points from a 3D generic model; d) applying RBF deformation to the generic 3D model based on the RBF parameters to determine a model for the synthesized 3D face; and e) determining texture coordinates for the synthesized 3D face in 2D image space; wherein step b) comprises symmetrically aligning the feature points, and step e) comprises projecting the generic 3D model or the model for the synthesized 3D face into 2D image space and applying RBF deformation to the projected generic 3D model or the projected model for the synthesized 3D face.

Abstract: A Method for encoding a picture with a first region and a second region is described wherein the first region is encoded according to a first encoding scheme, the second region is encoded according to a second encoding scheme and the second encoding scheme is carried out taking a parameter representing the visual perception of the second region into account.

Abstract: Systems and methods for rendering an entertainment animation. The system can comprise a user input unit for receiving a non-binary user input signal; an auxiliary signal source for generating an auxiliary signal; a classification unit for classifying the non-binary user input signal with reference to the auxiliary signal; and a rendering unit for rendering the entertainment animation based on classification results from the classification unit.

Abstract: A method of measuring a quality of a test video stream, the method comprising measuring a content richness fidelity feature of the test video stream based on occurrences of color values in image frames of the test video stream; measuring a block-fidelity feature of the test video stream based on distortion at block-boundaries in the image frames of the test video stream; measuring a distortion-invisibility feature of the test video stream based on distortion at pixels of the image frames of the test video stream; and determining a quality rating for the test video stream based on the content richness fidelity feature, the block-fidelity feature and the distortion-invisibility feature measured.

Abstract: A Method for encoding a picture with a first region and a second region is described wherein the first region is encoded according to a first encoding scheme, the second region is encoded according to a second encoding scheme and the second encoding scheme is carried out taking a parameter representing the visual perception of the second region into account.

Abstract: A method for generating a quality oriented significance camp for assessing the quality of an image or video, comprising the steps of extracting features of the image or video, determining a perceptual quality requirement of at least one extracted feature and integrating the extracted features and the perceptual quality requirement of the at least one extracted feature to form an array of significance level values, thereby generating the quality oriented significance map.

Abstract: A method for use in a real-time video encoder based on two processing means to optimise the use of computing power of the processing means. This is achieved by dynamically load-balancing between two processing means. The load pattern is determined with measures for the progress of motion estimation in one processing means and the idle time in the other. Adaptive adjustment of load balancing is fulfilled via making a decision on whether the DCT/IDCT/Quantization/Dequantization sub-process is skipped for a macroblock. The invention is not constrained to particular motion estimation techniques.
