摘要： Integrating features is disclosed, including: determining a value associated with a temporal feature for a point; determining a value associated with a spatial feature associated with the temporal feature; including the value associated with a spatial feature and the value associated with the temporal feature into a feature vector; and using the feature vector to decode for a character. Determining a transform is also disclosed, including: determining, for a point associated with a sequence of points, a set of points including: the point, a first subset of points of the sequence preceding a sequence position associated with the point, and a second subset of points following the sequence position associated with the point; and determining the transform associated with the point based at least in part on the set of points.

摘要： A first technique of recognizing content is disclosed, including: determining a first value representative of a pixel content present at a first set of pixels associated with a first distance from a pixel under consideration; determining a second value representative of a pixel content present at a second set of pixels associated with a second distance from the pixel under consideration; and using the first and second values to compute one or more spatial features associated with the pixel under consideration for purposes of content recognition. A second technique of recognizing content is also disclosed, including: determining, for a pixel, a first value representative of a first feature associated with a set of pixels associated with a first direction from the pixel; and determining, for the pixel, a second value representative of a second feature associated with a set of pixels associated with a second direction from the pixel.

摘要： The invention relates to a device for the verification of time-dependent, user-specific signals which includes means for generating a set of feature vectors which serve to provide an approximative description of an input signal and are associated with selectable sampling intervals of the signal; means for preparing an HMM model for the signal; means for determining a first probability value which describes the probability of occurrence of the set of feature vectors, given the HMM model, and a threshold decider for comparing the first probability value with a threshold value and for deciding on the verification of the signal. In order to achieve an improved threshold value determination with an improved error rate for the verification without using additional original signals from a user whereby the device is initialized for this user, it is proposed to make the threshold value dependent on an automatically determined, person-dependent second probability value which is formed by training signals used for training the HMM model and by at least one additional validation signal which is not used for the training.
