摘要： The present invention relates to a computer implemented system for animating a virtual object or digital entity. It has particular relevance to animation using biologically based models, or behavioural models particularly neurobehavioural models. There is provided a plurality of modules having a computational element and a graphical element. The modules are arranged in a required structure and have at least one variable and being associated with at least one connector. The connectors link variables between modules across the structure, and the modules together provide a neurobehavioural model. There is also provided a method of controlling a digital entity in response to an external stimulus.

摘要： Computational structures provide Embodied Agents with memory which can be populated in real time from Experience, and/or or authored. Embodied Agents (which may be virtual objects, digital entities or robots) are provided with one or more Experience Memory Stores which influence or direct the behaviour of the Embodied Agents. An Experience Memory Store may include a Convergence Divergence Zone (CDZ), which simulates the ability of human memory to represent external reality in the form of mental imagery or simulation that can be re-experienced during recall. A Memory Database be generated in a simple, authorable way, enabling Experiences to be learned during live operation of the Embodied Agents or authored. Eligibility-Based Learning determines which aspects from streams of multimodal information are stored in the Experience Memory Store.

摘要： Systems and methods for image retargeting are provided. Image data may be acquired that includes motion capture data indicative of motion of a plurality of markers disposed on a surface of a first subject. Each of the markers may be associated with a respective location on the first subject. A plurality of blendshapes may be calculated for the motion capture data based on a configuration of the markers. An error function may be identified for the plurality of blendshapes, and it may be determined that the plurality of blendshapes can be used to retarget a second subject based on the error function. The plurality of blendshapes may then be applied to a second subject to generate a new animation.

摘要： To realistically animate a String (such as a sentence) a hierarchical search algorithm is provided to search for stored examples (Animation Snippets) of sub-strings of the String, in decreasing order of sub-string length, and concatenate retrieved sub-strings to complete the String of speech animation. In one embodiment, real-time generation of speech animation uses model visemes to predict the animation sequences at onsets of visemes and a look-up table based (data-driven) algorithm to predict the dynamics at transitions of visemes. Specifically posed Model Visemes may be blended with speech animation generated using another method at corresponding time points in the animation when the visemes are to be expressed. An Output Weighting Function is used to map Speech input and Expression input into Muscle-Based Descriptor weightings
