Title: On-set facial performance capture and transfer to a three-dimensional computer-generated model
Inventor: STEPHANE GRABLI
IPC: G06T19/00
Filed: 2020-03-05
Abstract: A method of transferring a facial expression from a subject to a computer generated character includes receiving: a plate 502 with an image of the subject’s facial expression, a three-dimensional parameterized deformable model 504 of the subject’s face where different facial expressions of the subject can be obtained by varying values of the model parameters, a model of a camera rig used to capture the image, and a virtual lighting model that estimates lighting conditions when the image was captured. The method can solve for the facial expression in the plate by executing a deformation solver to solve for at least some parameters of the deformable model with a differentiable renderer 506 and shape from shading techniques, using, as inputs, the 3D parameterized deformable model, the camera rig model and the virtual lighting model over a series of iterations to infer geometry of the facial expression and generate a final facial mesh 520 using the set of parameter values of the deformable model. This results in a facial expression that closely matches the expression of the subject. It is useful for capturing a performance of an actor in film set conditions without the use of a head-mounted camera.

Title: Method, computer program and apparatus for comparing a second document with a first document
Inventor: David Sean Hobbs
IPC: G06F40/194
Filed: 2020-04-07
Abstract: A first document is compared with a subsequently published second document. The text of the documents is parsed (20, 22) to identify the terms in the documents. For each document, the unique terms are identified (24, 26), i.e. a list is compiled of all terms appearing at least once in the document. A measure of the importance of each unique term present in the second document is obtained (28), e.g. based on the number of occurrences of the term. For each unique term of the first document, the unique term of the second document which is most similar is identified, as determined by a similarity measure (30, 32). An affinity measure for the unique terms in the first document is obtained (34) based on the importance and similarity scores of the identified most similar term in the second document. An affinity score for the likeness of the second document to the first document is obtained from the affinity measures (36).
