Drop-out Color In Image (i.e., Color To Be Removed) Patents (Class 382/163)
  • Patent number: 10726299
    Abstract: A point cloud compression approach that exploits HEVC for compression of both the geometry and color data is described herein. Although both the geometry and color could be compressed in a lossy fashion, the point cloud compression approach is suggested for the scenario of lossless geometry and lossy color coding. Both geometry and color data are first mapped into 2D images and then compressed by HEVC. A sorting technique is used to sort the geometry data to make it as correlated as possible when it is mapped to a 2D image. For color coding, clustering is used to put similar colors in a point cloud into spatial neighbors in the mapped 2D image. This significantly avoids color leaking due to quantization errors to neighbor points in 3D. The results show that much better compression is achieved compared to the Anchor when it is configured for lossless geometry coding.

  • Patent number: 8805064
    Abstract: The embodiments discussed herein involve flood filling a region with anti-aliasing. In forming a fill region, a candidate pixel can be included in the region based on a color of the pixel and also a color of a neighbor of the point. The inclusion basis may be a color distance between a seed color and the points, and a color distance between the seed color and the point's neighbor. Points in the region may be weighted according to their color distance relative to the seed color, where the color distance can also take into account alpha values. Flood filling may be anti-aliased by assigning alpha values to pixels in gaps between corners of the fill region, where an alpha value may be proportional to a point's contribution to the gap. Dimples in a fill region may be tested for and used to determine which of two flood fill algorithms to use.

  • Publication number: 20140193067
    Abstract: A method for converting a full color image to a monochrome image is provided, wherein the color values of pixels are decomposed in a luminance and a chrominance component. Both components are converted to a grayscale value representing an intensity of a pixel. The luminance grayscale value is in a limited range close to a light end of the available grayscale. The chrominance grayscale value is closer to the dark end of the available grayscale when the chrominance component of the color value is larger. The darkest value of the two converted values is selected for a corresponding pixel. The effect of this conversion is that colored pixels are darker than colorless pixels, which is useful to highlight parts of a monochrome image that stand out because of their color in a full color image. It is particularly useful to help color blind people recognize colored parts of an image.

  • Publication number: 20140093162
    Abstract: A color separating unit separates a color image into plural color components to generate images of respective colors. A periodicity determining unit determines, for each of the color images, whether an image region including a target pixel whose pixel value is to be interpolated is a periodic region in which pixel values vary periodically. A first generating unit generates pixel values of the respective colors of a pixel using a first interpolation method. A second generating unit generates pixel values of the respective colors of a pixel using a second interpolation method. A control unit determines which one of the first and second generating units is to be used for generating pixel values of the respective colors of the target pixel. A pixel value combining unit combines candidate pixel values which are the pixel values of the respective colors of the target pixel to calculate a combined pixel value.

  • Patent number: 8682068
    Abstract: A representative pixel value calculation unit (120) divides an image represented by raw data (D0) into a plurality of blocks and calculates representative pixel values (S) for each block. A detection unit (130) detects an object block which is a block including a blown-out highlight or a blocked-up shadow, from among the plurality of blocks. A B-detection unit (134) of the detection unit (130) performs a first detection processing for obtaining one of a difference between a color represented by the representative pixel values and gray, and a value that can approximately represent the difference, as a characteristic value, and for detecting, as the object block, a block in which the characteristic value is equal to or smaller than a first threshold. Consequently, blown-out highlights or blocked-up shadows included in an image can be detected at higher speed, and the omission of detection can be prevented.

  • Patent number: 8675009
    Abstract: Some embodiments provide a method for editing an image that includes several pixels having pixel values in a color space. The method identifies (i) a shape in a plane of two dimensions of the color space and (ii) a range in a third dimension of the color space over which the first shape is propagated to form a first volume in the color space. Pixels whose pixel values are in the first volume of the color space are fully selected. The method displays a deformable curve along the third dimension that represents the manner in which the shape is propagated over the range of the color space.

  • Patent number: 8638993
    Abstract: Systems for segmenting human hairs and faces in color images are disclosed, with methods and processes for making and using the same. The image may be cropped around the face area and roughly centered. Optionally, the illumination environment of the input image may be determined. If the image is taken under dark environment or the contrast between the face and hair regions and background is low, an extra image enhancement may be applied. Sub-processes for identifying the pose angle and chin contours may be performed. A preliminary mask for the face by using multiple cues, such as skin color, pose angle, face shape and contour information can be represented. An initial hair mask by using the abovementioned multiple cues plus texture and hair shape information may be created. The preliminary face and hair masks are globally refined using multiple techniques.
