  • Patent number: 10650490
    Abstract: Environmental map generation techniques and systems are described. A digital image is scaled to achieve a target aspect ratio using a content aware scaling technique. A canvas is generated that is dimensionally larger than the scaled digital image and the scaled digital image is inserted within the canvas thereby resulting in an unfilled portion of the canvas. An initially filled canvas is then generated by filling the unfilled portion using a content aware fill technique based on the inserted digital image. A plurality of polar coordinate canvases is formed by transforming original coordinates of the canvas into polar coordinates. The unfilled portions of the polar coordinate canvases are filled using a content-aware fill technique that is initialized based on the initially filled canvas. An environmental map of the digital image is generated by combining a plurality of original coordinate canvas portions formed from the polar coordinate canvases.

  • Patent number: 10616443
    Abstract: An auto-rotation module having a single-layer neural network on a user device can convert a document image to a monochrome image having black and white pixels and segment the monochrome image into bounding boxes, each bounding box defining a connected segment of black pixels in the monochrome image. The auto-rotation module can determine textual snippets from the bounding boxes and prepare them into input images for the single-layer neural network. The single-layer neural network is trained to process each input image, recognize a correct orientation, and output a set of results for each input image. Each result indicates a probability associated with a particular orientation. The auto-rotation module can examine the results, determine what degree of rotation is needed to achieve a correct orientation of the document image, and automatically rotate the document image by the degree of rotation needed to achieve the correct orientation of the document image.

  • Patent number: 10318803
    Abstract: In a text line segmentation process, connected components (CCs) in document image are categorized into three subsets (normal, large, small) based on their sizes. The centroids of the normal size CCs are used to perform line detection using Hough transform. Among the detected candidate lines, those with line bounding box heights greater than a certain height are removed. For each normal size CC, if its bounding box does not overlap the bounting box of any line with an overlap area greater than a predefined fraction of the CC bounding box, a new line is added for this CC, which passes through the centroid of the CC and has an average slant angle. Each large size CCs are broken into two or more CCs. All CCs are then assigned to the nearest lines. A refinement method is also described, which can take any text line segmentation result and refine it.

  • Patent number: 8942512
    Abstract: An image registration method is disclosed for processing a distorted image into a registered image that is aligned with reference to an original image. Distortions from the original image may include scaling, rotation, and noise. The method is based on correlating Radon transforms of both images to determine the rotation angle, and the scaling factor is determined by dividing averages of the overall luminance of each image on the assumption that any added noise will cancel. The Fast Fourier Transform (FFT) is used to estimate global spatial shifts. In one embodiment, the distorted image is first scaled to the size of the original image before being rotated. In another embodiment, the original image is first scaled to the size of the distorted image before rotating the distorted image, and finally scaling it to match the original image. A corresponding system for image registration is also provided.

  • Patent number: 8885973
    Abstract: The invention relates to a method of determining the distortions in the projection system of a TEM, and a method of correcting for these aberrations. The aberrations are determined by collecting a large number of images of a sample, the sample slightly displaced between each acquisition of an image. On the images sub-fields (303, 304-i) showing identical parts of the sample are compared. These sub-fields (303, 304-i) will show small differences, corresponding to differential aberrations. In this way the differential aberrations in a large number of points can determined, after which the aberrations for each point can be determined by integration. By now correcting the position of each detected pixel in an image to be displayed, the displayed image has much reduced aberrations. An advantage of the method according to the invention is that no highly accurate steps of the sample are needed, nor is a sample with known geometry needed.

    Abstract: A portion within an image in which a plurality of objects (21 and 22) overlap is partitioned into a plurality of small regions (31a and 32a), each of the units of identification information for the plurality of objects (21 and 22) is assigned to a dot corresponding to the plurality of small regions (31a and 32a), and thereby, identification-use layout information is generated, whereby even if a plurality of objects overlap upon a layout of a display image, upon the layout of the identification-use layout information that has been generated for identifying the plurality of objects, the identification information corresponding to each object does not overlap. As a result, it is possible to identify each object by the identification information acquired from the position of the cursor.

  • Publication number: 20140198981
    Abstract: Embodiments of a processing systems and methods can unbend an image of facing pages of a bound book. An exemplary processing system can comprise an edge-detection unit, a keystone-correction unit, a flattening unit, and a conversion unit. After an image is received by the processing system, the image can be processed in turn by each unit. The edge-detection unit can identify edges of a document in the image. The keystone-correction unit can reduce or remove keystoning in the image, thereby correcting horizontal distortion of the document. The flattening unit can flatten or straighten text or objects in the image, thereby correcting vertical distortion of the document. The conversion unit can convert the image to a desired color profile. Accordingly, the processing system can process an original image into a more easily readable and digitally manipulable image.

  • Patent number: 8755590
    Abstract: The technology disclosed relates to scanning of large flat substrates for reading and writing images. Examples are flat panel displays, PCB's and photovoltaic panels. Reading and writing is to be understood in a broad sense: reading may mean microscopy, inspection, metrology, spectroscopy, interferometry, scatterometry, etc. of a large workpiece, and writing may mean exposing a photoresist, annealing by optical heating, ablating, or creating any other change to the surface by an optical beam. In particular, we disclose a technology that uses a rotating or swinging arm that describes an arc across a workpiece as it scans, instead of following a traditional straight-line motion.

  • Patent number: 8750647
    Abstract: Methods and a computer program product for deriving a super-resolution image of a physical object, the super-resolution image characterized by a resolution exceeding a “camera imaging resolution” associated with each of a sequence of lower-resolution images of the physical object. The sequence of images of the physical object is obtained at a plurality of relative displacements with respect to the object. An offset is passively associated with each of the plurality of images to derive effective camera movement, allowing for calculation of a kinetic point spread function on the basis of the effective camera movement. The image sequence is deconvolved, using the kinetic point spread function, to solve for a high-resolution image. Various applications such as portable cameras and infrared imaging for energy conservation are described.

  • Patent number: 8724924
    Abstract: Systems and methods for matching a received image with a template image are disclosed herein. Such systems and methods can advantageously enable an image captured by a mobile device (such as a smartphone or digital camera) to be correctly identified by the processing application. In some embodiments, the received image is first resized in one or both dimensions in order to match or approximately match the dimensions of a given template. The received image and template image can then be superimposed. Next, an optimal translative transformation value can be calculated in order to generate a confidence level for the current possible match. After confidence levels for each template are generated and recorded, the template with the highest confidence level can be selected as the best match for the received image.

  • Patent number: 8723886
    Abstract: Systems, devices, features, and methods for generating and/or using a multi-layered image are disclosed. For example, a method of creating a multi-layered image from a three-dimensional model of a geographic area includes receiving three-dimensional graphical object data that represents a geographic area. The three-dimensional graphical object includes multiple geographic features. A first graphical layer of a first geographic feature of the three-dimensional graphical object is rendered as a first independent image layer. A second graphical layer of a second geographic feature of the three-dimensional graphical object is rendered as a second independent image layer. The first graphical layer and the second graphical layer are combined or overlaid to form the multi-layered image. Also, removal of layers may occur in a reverse order of their creation and/or may avoid causing gaps within the other layers not removed.

  • Patent number: 8712190
    Abstract: Provided are a collating device, a processing method and a collation program, in which a reference line is extracted from an image and each partial image is moved in a manner that the reference line becomes a predetermined one thereby to correct the image, and in which the corrected image is collated so that an authentication result can be obtained for a short time period without any rotating operation. At first, a reference line extracting unit extracts the center line or the contour line of the image as the reference line. Next, an image correcting unit moves each partial image in parallel thereby to correct the image so that the reference line obtained by the reference line extracting unit becomes a predetermined one. Moreover, an image collating unit collates the image corrected by the image correcting unit and a predetermined image to acquire an authentication result.

  • Patent number: 8670634
    Abstract: Embodiments of the present invention provide a system for performing image conversion operations. The system starts by receiving a request from a client for one or more pixel buffers containing a pixel-formatted, cropped, geometrically transformed, and/or color matched version of an image representation. The system then determines if a provider can provide the one or more pixel buffers. If so, the system calls the provider to generate the one or more pixel buffers containing the pixel-formatted, cropped, geometrically transformed, and/or color matched version of the image representation. Otherwise, the system calls the provider to generate one or more intermediate pixel buffers, generates a sequence of converters for converting the one or more intermediate pixel buffers, and calls the sequence of converters to generate the one or more pixel buffers containing the pixel-formatted, cropped, geometrically transformed, and/or color matched version of the image representation.
