  • Patent number: 10002412
    Abstract: A device for removing haze from an image includes an image decomposer that decomposes a near-infrared (NIR) image to generate an NIR detail layer image and decomposes an RGB image to generate an RGB detail layer image and an RGB base layer image, a weight generator that generates a mixing weight value based on a similarity between high frequency (HF) components of the NIR image and the RGB image, a detail layer mixer that mixes the NIR detail layer image and the RGB detail layer image based on the mixing weight value to generate a mixed RGB detail layer image, a base layer dehazer that removes haze from the RGB base layer image to generate a compensated RGB base layer image, and an adder that adds the mixed RGB detail layer image and the compensated RGB base layer image to generate an output RGB image.

  • Patent number: 9998628
    Abstract: Disclosed are methods and multi-function devices for auto-correction of shadow effects in a scanned image. The method includes receiving a first image including a colored twin-page scanned document including at least one of a shadow region in a central part of the first image, at least one darker region caused at one or more borders of the first image, and distorted orientation with respect to a base of the first image; re-positioning the shadow region present in the central part to generate a re-positioned first binary image such that the shadow region becomes perpendicular to the base; detecting a shadow region in a central region of the re-positioned first binary image; removing the detected at least one shadow region from the re-positioned first binary image to generate a second image; and correcting a skewed orientation of each of a cropped left side and right side of the second image.

  • Patent number: 9898681
    Abstract: An apparatus and method for detecting an object using a multi-directional integral image are disclosed. The apparatus includes an area segmentation unit, an integral image calculation unit, and an object detection unit. The area segmentation unit places windows having a size of x*y on a full image having w*h pixels so that they overlap each other at their edges, thereby segmenting the full image into a single area, a double area and a quadruple area. The integral image calculation unit calculates a single directional integral image for the single area, and calculates multi-directional integral images for the double and quadruple areas. The object detection unit detects an object for the full image using the single directional integral image and the multi-directional integral images.

  • Patent number: 9875415
    Abstract: An automated, computerized method is provided for processing an image. The method includes the steps of arranging a digital camera on a vehicle body, operating the digital camera to provide an image file depicting an image of a scene related to vehicle operation on a road, in a computer memory, receiving from the memory the image file depicting pixels of an image of the scene related to vehicle operation on a road, and using an analysis of the pixels to generate an illumination invariant image of the scene. The illumination-invariant image is converted to a grayscale image and the grayscale image is then converted to an illumination-invariant color image.

  • Patent number: 9787874
    Abstract: Determination information is obtained to determine a degradation characteristic of sharpness of an image formed by an image forming apparatus. One of a plurality of recovery processing parameters used to recover sharpness of an image is selected based on the determination information, and characteristics of the plurality of recovery processing parameters are different from each other. Recovery processing of sharpness is performed on image data using the selected recovery processing parameter. When the degradation characteristics of sharpness are visually and substantially the same, the same recovery processing parameter is selected.
