  • Patent number: 10354370
    Abstract: An image processor includes a curve generator and a gradation correcting unit. Based on a predetermined correspondence relationship between average luminance of an image and a gradation correction curve, the curve generator generates, in accordance with average luminance of an input image, a common curve, i.e. a gradation correction curve used to correct a gradation of the input image. The gradation correcting unit uses in common the common curve generated by the curve generator for red, green, and blue color signals of the input image to correct gradations of the red, green, and blue color signals. Based on first average luminance, i.e. an average value of luminance of a first region in the input image, second average luminance, i.e. an average value of luminance of a predetermined-colored second region included in the first region, and an area of the second region, the curve generator generates a common curve.

  • Patent number: 10267635
    Abstract: A high-definition map system receives sensor data from vehicles travelling along routes and combines the data to generate a high definition map for use in driving vehicles, for example, for guiding autonomous vehicles. A pose graph is built from the collected data, each pose representing location and orientation of a vehicle. The pose graph is optimized to minimize constraints between poses. Points associated with surface are assigned a confidence measure determined using a measure of hardness/softness of the surface. A machine-learning-based result filter detects bad alignment results and prevents them from being entered in the subsequent global pose optimization. The alignment framework is parallelizable for execution using a parallel/distributed architecture. Alignment hot spots are detected for further verification and improvement. The system supports incremental updates, thereby allowing refinements of subgraphs for incrementally improving the high-definition map for keeping it up to date.

  • Patent number: 10262201
    Abstract: Extracting financial card information with relaxed alignment comprises a method to receive an image of a card, determine one or more edge finder zones in locations of the image, and identify lines in the one or more edge finder zones. The method further identifies one or more quadrilaterals formed by intersections of extrapolations of the identified lines, determines an aspect ratio of the one or more quadrilateral, and compares the determined aspect ratios of the quadrilateral to an expected aspect ratio. The method then identifies a quadrilateral that matches the expected aspect ratio and performs an optical character recognition algorithm on the rectified model. A similar method is performed on multiple cards in an image. The results of the analysis of each of the cards are compared to improve accuracy of the data.

  • Patent number: 10249029
    Abstract: Methods and systems for an image construction component capable of generating pixel information for certain regions of an image based on other, existing regions of the image. For example, the image construction component may identify a target block of pixels for which to generate pixel information and then use pixel information for pixels surrounding the target block of pixels in order to identify similar image information within pixels in another part of the image. These identified pixels may then be used in defining the pixel information of the target block of pixels and also used in blending the target block of pixels with the defined pixels surrounding the target block of pixels.

  • Patent number: 10250882
    Abstract: Innovations in control and use of chroma quantization parameter (“QP”) values that depend on luma QP values. More generally, the innovations relate to control and use of QP values for a secondary color component that depend on QP values for a primary color component. For example, during encoding, an encoder determines a QP index from a primary component QP and secondary component QP offset. The encoder maps the QP index to a secondary component QP, which has an extended range. The encoder outputs at least part of a bitstream including the encoded content. A corresponding decoder receives at least part of a bitstream including encoded content. During decoding, the decoder determines a QP index from a primary component QP and secondary component QP offset, then maps the QP index to a secondary component QP, which has an extended range.

  • Patent number: 10235741
    Abstract: An image correction apparatus generates a reduced smoothed image by smoothing a reduced image created from an input image; detects at least one edge pixel on the reduced image or the reduced smoothed image; calculates, for each pixel of the reduced image, a reflectance component of an object; calculates a correction factor having a value based on a reflectance component in accordance with a distribution of reflectance components other than the reflectance component of the edge pixel; generates an enlarged smoothed image by enlarging the reduced smoothed image; and generates a corrected image by calculating a luminance value of each pixel of the corrected image based on the correction factor and the reflectance component based on a ratio of a luminance value of a corresponding pixel of the input image to a luminance value of a corresponding pixel of the enlarged smoothed image.

  • Patent number: 10200672
    Abstract: Customer wide angle lenses and methods and apparatus for using such lenses in individual cameras as well as pairs of cameras intended for stereoscopic image capture are described. The lenses are used in combination with sensors to capture different portions of an environment at different resolutions. In some embodiments ground is capture at a lower resolution than sky which is captured at a lower resolution than a horizontal area of interest. Various asymmetries in lenses and/or lens and sensor placement are described which are particularly well suited for stereoscopic camera pairs where the proximity of one camera to the adjacent camera may interfere with the field of view of the cameras.

  • Patent number: 10147166
    Abstract: This invention provides methods for spatially localized image editing. For example, an input image is divided into multiple bins in each dimension. For each bin, a histogram is computed, along with local image statistics such as mean, medium and cumulative histogram. Next, for each tile, a type of adjustment is determined and applied, including adjustment associated with Exposure, Brightness, Shadows, Highlights, Contrast, and Blackpoint. The adjustments are done for all tiles in the input image to render a small adjustment image. The small image is then interpolated, for example, using an edge-preserving interpolation, to get a full size adjustment image with adjustment curve for each pixel. Subsequently, per-pixel image adjustments can be performed across an entire input image to render a final adjusted image.

  • Patent number: 10134359
    Abstract: Improving the visibility of the dark portion and to prevent the degradation of image quality caused by excessive correction. A reflectance calculation unit is storing a parameter RGain for adjusting the amplitude of a reflectance component R. An illumination light correction unit generates a corrected illumination light component L1 from an illumination light component L and a formula L1=(log(LAmp*L+1))/(log(LAmp+1)). An image resynthesis unit obtains a corrected illumination light component L? from L?=LGain*L1+(1?LGain)*L. The image resynthesis unit also calculates a corrected image Iout from the corrected illumination light component L? and the corrected reflectance R?, as well as from a formula Iout=exp(log L?+RGain(log I?log L)). The value of the corrected illumination light component (L?) is determined based on the ratio (LGain) at which the output value of the correction function (L1) and the original illumination light component (L) are combined.
