Abstract: A method, non-transitory computer readable medium and apparatus for generating graphical chromophore maps are disclosed. For example, the method includes receiving an image of a customer from a mobile endpoint device of the customer, wherein the image is taken via the mobile endpoint device of the customer, converting RGB values of the image into a spectral representation, performing a constrained independent component analysis (ICA) on the spectral representation to obtain three or more independent components that are ordered, generating a first graphical chromophore map of a first independent component of the three or more independent components that are ordered and a second graphical chromophore map of a second independent component of the three or more independent components that are ordered and transmitting the first graphical chromophore map and the second graphical chromophore map to the mobile endpoint device of the customer for display.

Abstract: A mobile electronic device processes a sequence of images to identify and re-identify an object of interest in the sequence. An image sensor of the device, receives a sequence of images. The device detects an object in a first image as well as positional parameters of the device that correspond to the object in the first image. The device determines a range of positional parameters within which the object may appear in a field of view of the device. When the device detects that the object of interest exited the field of view it subsequently uses motion sensor data to determine that the object of interest has likely re-entered the field of view, it will analyze the current frame to confirm that the object of interest has re-entered the field of view.

Abstract: In a system for detecting location of an object inside of a building, an image capture device of a mobile electronic device captures an image of a boundary of a room in which the portable electronic device is positioned. The system extracts features of a boundary (ceiling, wall or floor) in the image to determine whether the mobile device is in a known location. When the system identifies a known location, it will take an action that provides the portable electronic device with additional functionality at the identified known location. Such functionality may include connecting to a wireless network or communicating with a stationary device at the known location.

Abstract: The embodiments include systems and methods for guiding a user to capture two flash images of a document page, and selectively fuse the images to produce a binary image of high quality and without loss of any content. Each individual image may have an FSR where the content is degraded/lost due to the flash light. The idea is to first guide the user to take two images such that there is no overlap of flash-spots in the document regions. The flash spots in both images are detected and assessed for quality and extent of degradation in both images. The image with lower degradation is chosen as the primary image and the other image as secondary, to minimize fusing artifacts. The region in secondary image corresponding to the FSR in the primary is aligned to the primary region using a multiscale alignment technique. The primary image and aligned FSR are binarized and fused in the vicinity of the flashspot in the primary using an intelligent technique that minimizes fusion boundary artifacts such as cutting of characters and words.

Abstract: A method, non-transitory computer readable medium and apparatus for generating an interactive image of facial skin of a user that is displayed via a mobile endpoint device of the user are disclosed. For example, the method includes displaying a guide to position a face of the user, capturing an image of the face of the user, transmitting the image to a facial skin analysis server for analyzing one or more parameters of the facial skin of the user, receiving the interactive image of the face of the user that includes metadata associated with the one or more parameters of the facial skin that were analyzed by the facial skin analysis server, and displaying the interactive image of the face of the user.

Abstract: A system generates a secure barcode by: identifying a primary pattern for a two-dimensional barcode to be printed on a substrate, wherein the primary pattern comprises of a set of dark cells and a set of light cells; identifying a two-dimensional micro-shape, wherein the micro-shape has a size that is no larger than a size of each cell of the two-dimensional barcode; generating a secondary pattern comprising a plurality of the micro-shapes; and superimposing the secondary pattern with the primary pattern for the two-dimensional barcode to yield a secure barcode. The resulting two-dimensional barcode includes a primary pattern comprising a set of dark cells and a set of light cells, where the sets represent encoded data, along with a secondary pattern of micro-shapes that are superimposed with the primary pattern.

Abstract: Methods, systems, and processor-readable media for pruning a training dictionary for use in detecting anomalous events from surveillance video. Training samples can be received, which correspond to normal events. A dictionary can then be constructed, which includes two or more classes of normal events from the training samples. Sparse codes are then generated for selected training samples with respect to the dictionary derived from the two or more classes of normal events. The size of the dictionary can then be reduced by removing redundant dictionary columns from the dictionary via analysis of the sparse codes. The dictionary is then optimized to yield a low reconstruction error and a high-interclass discriminability.
