摘要： Computer implemented method for detecting a hand gesture of a user, comprising: (a) Receiving sequential logic models each representing a hand gesture. The sequential logic model maps pre-defined hand poses and motions each represented by a hand features record defined by discrete hand values each indicating a state of respective hand feature. (b) Receiving a runtime sequence of runtime hand datasets each defined by discrete hand values scores indicating current state hand features of a user's moving hand which are inferred by analyzing timed images depicting the moving hand. (c) Submitting the runtime hand datasets and the pre-defined hand features records in SSVM functions to generate estimation terms for the runtime hand datasets with respect to the hand features records. (d) Estimating which of the hand gestures best matches the runtime sequence depicted in the timed images by optimizing score functions using the estimation terms for the runtime hand datasets.

摘要： Depth map correction using lookup tables is described. In an example depth maps may be generated that measure a depth to an object using differences in phase between light transmitted from a camera which illuminates the object and light received at the camera which has been reflected from the object. In various embodiments depth maps may be subject to errors caused by received light undergoing multiple reflections before being received by the camera. In an example a correction for an estimated depth of an object may be computed and stored in a lookup table which maps the amplitude and phase of the received light to a depth correction. In an example the amplitudes and frequencies of each modulation frequency may be to access lookup table which stores corrections for the depth of an object and which allows an accurate depth map to be obtained.

摘要： Computer implemented method for computing a feature dataset classifying a pose of a human hand, comprising: (a) Selecting a global orientation category (GOC) defining a spatial orientation of a human hand in a 3D space by applying GOC classifying functions on a received image segment depicting the hand. (b) Identifying in-plane rotation by applying in-plane rotation classifying functions on the image segment, the in-plane rotation classifying functions are selected according to said GOC. (c) Aligning the image segment in a 2D plane according to the in-plane rotation. (d) Applying hand pose features classifying functions on the aligned image segment. Each one of the feature classifying functions outputs a current discrete pose value of an associated hand feature. (e) Outputting a features dataset defining a current discrete pose value for each of the hand pose features for classifying current hand pose of the hand.

摘要： A computer may identify an individual according to one or more biometrics based on various physiological aspects of the individual, such as metrics of various features of the face, gait, fingerprint, or voice of the individual. However, biometrics are often computationally intensive to compute, inaccurate, and unable to scale to identify an individual among a large set of known individuals. Therefore, the biometric identification of an individual may be supplemented by identifying one or more devices associated with the individual (e.g., a mobile phone, a vehicle driven by the individual, or an implanted medical device). When an individual is registered for identification, various device identifiers of devices associated with the individual may be stored along with the biometrics of the individual. Individuals may then be identified using both biometrics and detected device identifiers, thereby improving the efficiency, speed, accuracy, and scalability of the identification.
摘要翻译： 计算机可以基于个体的各种生理方面根据一个或多个生物特征识别个体，例如个体的各种特征的度量，步态，指纹或个体的声音。 然而，生物识别通常对于计算，不精确和无法扩展以在一大群已知个体中识别个体而计算密集。 因此，可以通过识别与个人（例如，移动电话，由个体驱动的车辆或植入的医疗设备）相关联的一个或多个设备来补充个体的生物特征识别。 当个人被注册用于识别时，可以与个体的生物特征一起存储与个人相关联的设备的各种设备标识符。 然后可以使用生物特征和检测到的设备标识符来识别个体，从而提高识别的效率，速度，准确性和可扩展性。

摘要： Examples are disclosed that relate to voice identification enrollment. One example provides a method of voice identification enrollment comprising, during a meeting in which two or more human speakers speak at different times, determining whether one or more conditions of a protocol for sampling meeting audio used to establish human speaker voiceprints are satisfied, and in response to determining that the one or more conditions are satisfied, selecting a sample of meeting audio according to the protocol, the sample representing an utterance made by one of the human speakers. The method further comprises establishing, based at least on the sample, a voiceprint of the human speaker.

摘要： A method for facilitating a remote conference includes receiving a digital video and a computer-readable audio signal. A face recognition machine is operated to recognize a face of a first conference participant in the digital video, and a speech recognition machine is operated to translate the computer-readable audio signal into a first text. An attribution machine attributes the text to the first conference participant. A second computer-readable audio signal is processed similarly, to obtain a second text attributed to a second conference participant. A transcription machine automatically creates a transcript including the first text attributed to the first conference participant and the second text attributed to the second conference participant.
