Image Segmentation Using Color Patents (Class 382/164)
  • Patent number: 8224075
    Abstract: Tools disclosed herein comprise progressive, paint stroke based region recognition and selection tools. Using these tools, a user may partially paint a region of interest directly on an image (by using a paint brush or other similar tool). Unlike conventional selection tools, a user is not required to paint the entire region pixel-by-pixel. Rather the desired region is automatically and intelligently recognized based on the partial selection. This is accomplished via a progressive selection algorithm. In addition, these tools provide the ability to quickly execute such region selections on multi-megapixel images.

  • Patent number: 8224073
    Abstract: A method and system for processing image data provides associated background metadata in a searchable format and reduces file size. MRC techniques are used to process input image data. It is known that the image data may be segmented to generate a background layer representing background attributes of the input image data. A background color value of the background layer is detected, and background metadata representing the color value is generated. The background metadata is associated with the image data (e.g., as a separate file, in the image header, etc.), thereby making the background metadata searchable and reducing the file size of the image data to be stored.

    Abstract: Methods and systems for automatically generating a mask delineating a region of interest (ROI) within an image containing skin are disclosed. The image may be of an anatomical area containing skin, such as the face, neck, chest, shoulders, arms or hands, among others, or may be of portions of such areas, such as the cheek, forehead, or nose, among others. The mask that is generated is based on the locations of anatomical features or landmarks in the image, such as the eyes, nose, eyebrows and lips, which can vary from subject to subject and image to image. As such, masks can be adapted to individual subjects and to different images of the same subjects, while delineating anatomically standardized ROIs, thereby facilitating standardized, reproducible skin analysis over multiple subjects and/or over multiple images of each subject.

  • Patent number: 8208171
    Abstract: The present invention aims to prevent a problem that an image on a document sheet is erased due to misdetection of a line-shaped noise. A copy machine 1 compares RGB values of a target pixel with averaged RGB values (Step S103). If only one of the RGB values has a difference that is greater than a prescribed value Ref2 (Step S103: YES), the copy machine 1 extracts the target pixel as a line-shaped noise pixel, and moves to a line-shaped noise correction (Step S108) while holding the address of the target pixel in a line-shaped noise address storing area 49b. If two of the RGB values have differences (Step S103: NO, Step S104: YES) and a difference between these two of the RGB values is no greater than a prescribed value Ref3 (Step S105: YES), the copy machine 1 extracts the target pixel as a line-shaped noise pixel, and moves to the line-shaped noise correction (Step S108) while holding the address of the target pixel in the line-shaped noise address storing area 49b.

    Abstract: An image segmentation system selects candidate images from an image collection. Image analysis on individual images proceeds by first detecting salient features on each image. Patches are centered on points of interest located on the salient features of the image. Each patch is gridded into blocks. The block feature vectors are merged to generate a patch feature vector. A fingerprint for each image is obtained by merging patch feature vectors across the image. Images with similar fingerprints are identified and geometric matching is performed to further select images with similar objects.

Unlike conventional feature extraction techniques that rely on point-based features, the TILT Extractor extracts texture regions from an image and derives global correlations or transformations of those regions in 3D (e.g., transformations including translation, rotation, reflection, skew, scale, etc.). These image domain transformations inherently provide information relative to an automatically determinable camera viewing direction. In other words, the TILT Extractor extracts low-rank regions and geometric correlations describing domain transforms of those regions relative to arbitrary camera viewpoints.

  • Patent number: 8165391
    Abstract: If a pixel of interest on a line of interest is located in an attribute region different from that in which a pixel immediately preceding the pixel of interest is located, the luminance value and color difference values of the pixel of interest are recorded in this order adjacent to data recorded in a data packet set for the line of interest (S811). If the pixel of interest is located in the same attribute region as that in which the preceding pixel is located, the luminance value of the pixel of interest is recorded adjacent to the data recorded in the data packet (S812). The data packet generated by executing the above recording process on each pixel forming the line is output.

  • Patent number: 8165407
    Abstract: Described is a bio-inspired vision system for object recognition. The system comprises an attention module, an object recognition module, and an online labeling module. The attention module is configured to receive an image representing a scene and find and extract an object from the image. The attention module is also configured to generate feature vectors corresponding to color, intensity, and orientation information within the extracted object. The object recognition module is configured to receive the extracted object and the feature vectors and associate a label with the extracted object. Finally, the online labeling module is configured to alert a user if the extracted object is an unknown object so that it can be labeled.

  • Patent number: 8164597
    Abstract: Exemplary embodiments of color conversion circuits and color conversion methods convert input color data into output color data. The input color data is positioned in a three-dimensional color space, which is divided into a plurality of unit cubes each having a fixed dimension. The input color data is converted by performing interpolations using conversion coefficients at vertexes of the unit cube within which the input color data is positioned. When the input color data is positioned on a gray axis of the color space, a substitution circuit substitutes some of the conversion coefficients such that the interpolation becomes a linear interpolation. As a result, it is assured that input color data positioned on the gray axis is converted to gray output color data.

  • Patent number: 8149456
    Abstract: Restriction information on a total colorant amount for a medium is obtained. Patches at grid points in a color space corresponding to a plurality of colorants at which the total colorant amount falls within a restriction represented by the restriction information, and a patch at a point surrounded by the patches are generated. Color values are obtained by measuring the colors of the patches printed on the medium. It is determined based on a color prediction value between the grid points whether the measured color values are appropriate, and if so, a color value at a grid point at which the total colorant amount exceeds the restriction is estimated based on the measured color values. A color separation table is created based on the measured color values and the estimated value.

  • Patent number: 8150150
    Abstract: A method and system of extracting a perceptual feature set for image/video segmentation are disclosed. An input image is converted to obtain a hue component and a saturation component, where the hue component is quantized into a number of quantum values. After weighting the quantized hue component with the saturation component, the weighted quantized hue component and the saturation component are subjected to a statistical operation in order to extract feature vectors. Accordingly, the method and system provide overall segmentation results that are very close to human interpretation.
