The MMR matching unit includes a segmenter for segmenting received images by content type, a distributor for distributing the images to corresponding content type index tables, and an integrator for integrating recognition results. The result is returned to the mobile device via the pre-processing server or MMR gateway. The present invention also includes a number of novel methods including a method for processing content-type specific image queries and for processing queries across multiple indexes.

Abstract: The disclosure includes a system and method for identifying multiple items in an image. A image recognition application receives a query image of items, computes features of the query image, for each feature finds an indexed image with closest matched features in a database, determines that the shape of the matched features is geometrically consistent, determines whether the query image matches the indexed image, responsive to the query image matching the indexed image, returns inliers, determines a region of interest where the match was found in the query image, removes inliers from the set of features to reduce the set of features and returns all matches found when the query image fails to match the indexed image.

Abstract: The disclosure includes a system and method for indexing synthetically modified images of a high quality image. An image recognition application receives images of a product, crops background regions from the images, scales the image based on a minimum value among width and height of the image and generates multiple image sizes, blurs the images, brightens the image and indexes the images as being associated with the product. The images can be of box-shaped packages that include four or six images or cylindrical packages that include, for example, eight images of the packages. The images can be indexed in a k-dimensional tree for faster retrieval.

Abstract: A system for displaying video on electronic paper displays to reduce video playback artifacts comprises an electronic paper display, a video display driver, a video transcoder, a display controller, a memory buffer and a waveforms module. The video display driver receives a re-formatted video stream, which has been processed by the video transcoder, from the memory buffer. The video display driver directs the video transcoder to process the video stream and generate pixel data. The video display driver loads waveforms into the frame buffer and updates display commands repeatedly to activate the display controller until the end of the video playback. The video display driver directs copying video frames sequentially one by one from the memory buffer to the frame buffer in real time during the video playback. The video transcoder receives a video stream for presentation on the electronic paper display and processes the video stream generating pixel data that is provided to the display controller.

Abstract: Multiframe reconstruction combines a set of acquired images into a reconstructed image. Here, which images to acquire are selected based at least in part on the content of previously acquired images. In one approach, a set of at least three images of an object are acquired at different acquisition settings. For at least one of the images in the set, the acquisition setting for the image is determined based at least in part on the content of previously acquired images. Multiframe image reconstruction is applied to the set of acquired images to synthesize a reconstructed image of the object.
