  • Patent number: 8442310
    Abstract: One or more techniques and/or systems are disclosed for compensating for affine distortions in handwriting recognition. Orientation estimation is performed on a handwriting sample to generate a set of likely characters for the sample. An estimated affine transform is determined for the sample by applying hidden Markov model (HMM) based minimax testing to the sample using the set of likely characters. The estimated affine transform is applied to the sample to compensate for the affine distortions of the sample, yielding an affine distortion compensated sample.

  • Publication number: 20130103383
    Abstract: Some implementations disclosed herein provide techniques and arrangements to enable translating language characters in media content. For example, some implementations receive a user selection of a first portion of media content. Some implementations disclosed herein may, based on the first portion, identify a second portion of the media content. The second portion of the media content may include one or more first characters of a first language. Some implementations disclosed herein may create an image that includes the second portion of the media content and may send the image to a server. Some implementations disclosed herein may receive one or more second characters of a second language corresponding to a translation of the one or more first characters of the first language from the server.

  • Patent number: 8369611
    Abstract: One or more techniques and/or systems are disclosed for constructing a compact handwriting character classifier. A precision constrained Gaussian model (PCGM) based handwriting classifier is trained by estimating parameters for the PCGM under minimum classification error (MCE) criterion, such as by using a computer-based processor. The estimated parameters of the trained PCGM classifier are compressed using split vector quantization (VQ) (e.g., and in some embodiments, scalar quantization) to compact the handwriting recognizer in computer-based memory.

  • Publication number: 20120280974
    Abstract: Dynamic texture mapping is used to create a photorealistic three dimensional animation of an individual with facial features synchronized with desired speech. Audiovisual data of an individual reading a known script is obtained and stored in an audio library and an image library. The audiovisual data is processed to extract feature vectors used to train a statistical model. An input audio feature vector corresponding to desired speech with which the animation will be synchronized is provided. The statistical model is used to generate a trajectory of visual feature vectors that corresponds to the input audio feature vector. These visual feature vectors are used to identify a matching image sequence from the image library. The resulting sequence of images, concatenated from the image library, provides a photorealistic image sequence with facial features, such as lip movements, synchronized with the desired speech. This image sequence is applied to the three-dimensional model.

  • Publication number: 20110280484
    Abstract: The disclosed architecture is a new feature extraction approach to handwriting recognition. Given an handwriting sample (e.g., from an online source), a sequence of time-ordered dominant points are extracted, which include stroke-endings, points corresponding to local extrema of curvature, and points with a large distance to the chords formed by pairs of previously identified neighboring dominant points. At each dominant point, a multi-dimensional feature vector is extracted, which includes a combination of coordinate features, delta features, and double-delta features.

  • Publication number: 20110157012
    Abstract: Techniques and systems for inputting data to interactive media devices are disclosed herein. In some aspects, a sensing device senses an object as it moves in a trajectory indicative of a desired input to an interactive media device. Recognition software may be used to translate the trajectory into various suggested characters or navigational commands. The suggested characters may be ranked based on a likelihood of being an intended input. The suggested characters may be displayed on a user interface at least in part based on the rank and made available for selection as the intended input.

  • Publication number: 20100262423
    Abstract: Described is a technology by which a feature compensation approach to speech recognition uses a high-order vector Taylor series (HOVTS) approximation of a model of distortions to improve recognition accuracy. Speech recognizer models trained with clean speech degrade when later dealing with speech that is corrupted by additive noises and convolutional distortions. The approach attempts to remove any such noise/distortions from the input speech. To use the HOVTS approximation, a Gaussian mixture model is trained and used to convert cepstral domain feature vectors to log spectrum components. HOVTS computes statistics for the components, which are transformed back to the cepstral domain. A noise/distortion estimate is obtained, and used to provide a clean speech estimate to the recognizer.

  • Publication number: 20100246941
    Abstract: Described is a technology by which handwriting recognition is performed using a precision constrained Gaussian model (PCGM) that requires far less memory than other models such as MQDF. Offline training, such as via maximum likelihood and/or minimum classification error techniques, provides classification data. The classification data includes basis matrices that are shared by classes, along with weighting coefficients and a mean vector corresponding to each class. The base matrices and weights are obtained by expanding a precision matrix for each class. In online recognition, received handwritten input (e.g., an East Asian character) is classified into a class, based upon the per-class mean vector and weighting coefficients, and the basis matrices, by a PCGM recognizer that outputs similarity scores for candidates and a decision rule that selects the most likely class.

  • Publication number: 20100239168
    Abstract: Described is a technology by which handwriting recognition is performed using a semi-tied covariance modeling (STC) that requires far less memory than other models such as MQDF. Offline training, such as via maximum likelihood and/or minimum classification error techniques, provides classification data. The classification data includes semi-tied transforms that are shared by classes, along with a class-dependent diagonal matrix and a mean vector corresponding to each class. The semi-tied transforms and class-dependent diagonal matrices are obtained by processing a precision matrix for each class. In online recognition, received handwritten input (e.g., an East Asian character) is classified into a class, based upon the class-dependent diagonal matrices and the semi-tied transforms, by a STC recognizer that outputs similarity scores for candidates and a decision rule that selects the most likely class.
