  • Patent number: 9665927
    Abstract: A method for enhancing at least one image within a series of images is provided. The method includes: selecting the series of images; upscaling each image within the series of images; selecting a reference image among the series of images; performing image registration to align series of images with the reference image; evaluating the series of aligned images for a subset of pixel locations that exhibit high cross-frame variation; performing learning processing to substantially reduce noise and exclude motion biases at the subset of pixel locations; performing pixel fusion from the series of aligned and processed images to produce the super-resolution reference image. A computer program product and an imaging system are disclosed.

  • Publication number: 20160093273
    Abstract: A Dynamic Vision Sensor (DVS) where pixel pitch is reduced to increase spatial resolution. The DVS includes shared pixels that employ Time Division Multiplexing (TDM) for higher spatial resolution and better linear separation of pixel data. The pixel array in the DVS may consist of multiple N×N pixel clusters. The N×N pixels in each cluster share the same differentiator and the same comparator using TDM. The pixel pitch is reduced (and, hence, the spatial resolution is improved) by implementing multiple adjacent photodiodes/photoreceptors that share the same differentiator and comparator units using TDM. In the DVS, only one quarter of the whole pixel array may be in use at the same time. A global reset may be done periodically to switch from one quarter of pixels to the other for detection. Because of higher spatial resolution, applications such as gesture recognition or user recognition based on DVS output entail improved performance.

  • Patent number: 8081209
    Abstract: A system and method for object classification based upon the fusion of a radar system and a natural imaging device using sparse code representation. The radar system provides a means of detecting the presence of an object within a predetermined path of a vehicle. Detected objects are then fused with the image gathered by the camera and then isolated in an attention window. The attention window is then transformed into a sparse code representation of the object. The sparse code representation is then compared with known sparse code representation of various objects. Each known sparse code representation is given a predetermined variance and subsequent sparse code represented objects falling within said variance will be classified as such. The system and method also includes an associative learning algorithm wherein classified sparse code representations are stored and used to help classifying subsequent sparse code representation.
