  • Publication number: 20170267251
    Abstract: Interacting with the driver based on the driver's context can keep help keep the driver alert. The context can be determined determining driver characteristics including the interests and by monitoring the circumstances surrounding the driver, such as the state of the driver using sensors included in the vehicle, the state of the vehicle, and the information about the driver's current locale. The characteristics and the monitored circumstances define the context of driver. Information of interest to the driver is obtained and is used to generate actions that are recommendable to the driver based on the driver's context. The actions are used to keep the driver alert.

  • Patent number: 9767349
    Abstract: A method for determining an emotional state of a subject taking an assessment. The method includes eliciting predicted facial expressions from a subject administered questions each intended to elicit a certain facial expression that conveys a baseline characteristic of the subject; receiving a video sequence capturing the subject answering the questions; determining an observable physical behavior experienced by the subject across a series of frames corresponding to the sample question; associating the observed behavior with the emotional state that corresponds with the facial expression; and training a classifier using the associations. The method includes receiving a second video sequence capturing the subject during an assessment and applying features extracted from the second image data to the classifier for determining the emotional state of the subject in response to an assessment item administered during the assessment.

  • Patent number: 9760789
    Abstract: A method, system, and computer-usable tangible storage device for robustly cropping and accurately recognizing license plates to account for noise sources and interfering artifacts are disclosed. License plate images and sub-images can be tightly cropped utilizing an image-based classifier and gradient-based cropping. An image-based classifier can identify the location of valid characters within the image. Because of a number of noise sources, such as, for example, residual plate rotation and shear in the characters within the image, the image-based classifier performs a “rough” identification of the image boundaries. An additional processing step utilizing gradient-based cropping is performed to fine-tune the license plate image boundaries. Gradient-based cropping eliminates unwanted border artifacts that could substantially impact the segmentation and license plate character recognition results.

  • Patent number: 9741249
    Abstract: As set forth herein, systems and methods are described that facilitate to analyze a video stream from a camera mounted on the side of a school bus, wherein a sub-set of video sequences showing cars illegally passing the stopped school bus are automatically identified through image and/or video processing. The described systems and methods provide a significant savings in terms of the amount of manual review that is required to identify such violations. The video sequences also can be analyzed further to additionally produce images of the license plate (for identification of the violator), thereby providing further reduction in required human processing and review time. In one embodiment, automatic license plate recognition (ALPR) is employed to identify text on the violator's license plate, as well as the state by which the license plate was issued, without requiring human review of the license plate image.

  • Publication number: 20170220854
    Abstract: A multimodal sensing system includes various devices that work together to automatically classify an action. A video camera captures a sequence of digital images. At least one other sensor device captures other sensed data (e.g., motion data). The system will extract video features from the digital images so that each extracted image feature is associated with a time period. It will extract other features from the other sensed data so that each extracted other feature is associated with a time period. The system will fuse a group of the extracted video features and a group of the extracted other features to create a fused feature representation for a time period. It will then analyze the fused feature representation to identify a class, access a data store of classes and actions to identify an action that is associated with the class, and save the identified action to a memory device.

  • Patent number: 9710727
    Abstract: A method and system for detecting anomalies in video footage. A training dictionary can be configured to include a number of event classes, wherein events among the event classes can be defined with respect to n-dimensional feature vectors. One or more nonlinear kernel function can be defined, which transform the n-dimensional feature vectors into a higher dimensional feature space. One or more test events can then be received within an input video sequence of the video footage. Thereafter, a determination can be made if the test event(s) is anomalous by applying a sparse reconstruction with respect to the training dictionary in the higher dimensional feature space induced by the nonlinear kernel function.

  • Patent number: 9697431
    Abstract: A device and method for providing a visual cue for improved text imaging on a mobile device. The method includes determining a minimum text size for accurate optical character recognition (OCR) of an image captured by the mobile device, receiving an image stream of a printed substrate, and displaying the image stream and a visual cue superimposed onto the image stream, wherein the visual cue is indicative of the minimum text size. The method further includes capturing a digital image of the image stream, wherein the digital image does not include the visual cue. Additionally, the method further includes notifying a user of the mobile device when text displayed within the image stream is at least as large as the minimum text size.

  • Publication number: 20170132785
    Abstract: The quality of surgeries in captured videos is modeled in a learning network. For this task, a dataset of surgical video is given with a corresponding set of scores that are labeled by reviewers, to learn a model for quality assessment of surgical procedures. A learned model is then used to automatically assess quality of a surgical procedure, which omits the need for professional experts to manually inspect such videos. The quality assessment of surgical procedures can be performed off-line or in real-time as the surgical procedure is being performed. Surgical actions in surgical procedures are also localized in space and time to provide a feedback to the surgeon as to which action can be improved.

  • Patent number: 9619686
    Abstract: Eliminate or reduce the impact of glare in printed information tag recognition applications using single- and multi-pose external illumination coupled with intelligent processing. A shelf imager can acquire shelf images for printed information tag localization and recognition. An external illuminator can provide at least one illumination condition/pose for shelf image acquisition in addition to lighting associated with the enclosed environment. A glare region of interest (ROI) detector can analyze all or a portion of the acquired shelf images for glare to determine whether additional images need to be acquired using different illumination conditions provided by the single- or multi-pose external illuminator or whether full or portion of acquired images need to be analyzed by a printed information tag locator and recognizer. A printed information tag locator and recognizer can analyze all or a portion of the acquired images to localize and recognize data printed on the printed information tags.
