  • Patent number: 8666175
    Abstract: A method and apparatus for detecting an object are provided. The method calculates a feature value based on features extracted from an input image by using a classifier of an ith stage, compares the calculated feature value with a first threshold value of the ith stage, compares the feature value with a second threshold value of the ith stage according to a result of the comparison between the feature value and the first threshold value of the ith stage, and jumps to a classifier of an i+2th stage according to a result of the comparison between the feature value and the second threshold value of the ith stage. By doing so, the method can avoid repeated calculations and can rapidly detect the object in the input image.

  • Patent number: 8644618
    Abstract: Systems and methods may automatically evaluate printed line weights in an image composition. An image composition may be received and the number of horizontal and vertical rows of pixels may be determined. The number of positive pixels in each of the horizontal and vertical rows may then be determined. An actual size of a pixel may be calculated. The actual size of a pixel may be multiplied by the number of positive pixels in each of the horizontal rows and each of the vertical rows to determine a positive line weight of each of the horizontal rows and each of the vertical rows. A predetermined minimum permissible positive line weight for the image composition may be identified and compared to the positive line weight of each of the horizontal rows and each of the vertical rows.

  • Patent number: 8644613
    Abstract: When image data are input from a memory card or the like, a printing apparatus detects face region captured in these image data. Where the size and position of a face region fall within permitted ranges therefor set in advance in a permitted range table derived via sense evaluation testing, the input image data is selected as a printing target candidate. If the face region size and position do not each fall within their permitted range, however, the image data is not selected as a printing target. As a result, image data suitable for printing can be efficiently selected as printing targets from image data that contain human faces.

  • Patent number: 8605986
    Abstract: A burr detection apparatus includes an imaging unit and a detection unit. The imaging unit captures an original image of a stencil. The original comprises black and white pixels. The detection includes a CPU and a memory. The CPU includes an extracting module, a deciding module, a counting module, and a comparing module. The extracting module obtains a matrix image with N*N pixels, wherein N is an odd number. The deciding module decides whether the center pixel of the matrix image is a black pixel. The counting module obtains a black pixel total counted among marginal pixels which position in the margin of the matrix image in a predetermined rule. The comparing module compares the black pixel total with a predetermined threshold number, and determines that the part of the stencil corresponding to the matrix image has a burr when the black pixel total is less than the threshold number.

  • Patent number: 8538174
    Abstract: A simple compression and decompression method provides excellent effects by reducing the storage capacity of an image memory, while adapting to the properties of image. On the basis of luminance information extracted by a luminance extraction block 110, a compression conversion rule setting block 120 sets a compression conversion rule to a compression conversion table 130. In accordance with this compression conversion rule, an image compression block 140 compresses original image data and holds the compressed image data in an image memory 150 along with a type of the compression conversion rule. This type of the compression conversion rule held in the image memory 150 is extracted by a decompression conversion rule setting block 160. In accordance with this type, a decompression conversion rule is set to a decompression conversion table 170.

  • Patent number: 8457394
    Abstract: The present invention relates to a method of detecting a skin-colored area using a variable skin color model. In the method, an initial skin-colored area is extracted from an input image using a skin color model, the initial skin-colored area being repeatedly extracted by adjusting a threshold value, which is a criterion for the selection of a skin-colored area, until a ratio of size of the extracted skin-colored area to size of the entire input image becomes less than a predetermined value. A skin-colored area is extracted by applying the threshold value determined in the first stage to the skin color model, the skin color model being modified by analyzing characteristics of object regions and noise regions of the skin-colored area. The skin-colored area detection method can obtain a high skin-colored object detection rate and a high false alarm rate even under various lighting and background conditions.

  • Patent number: 8452100
    Abstract: A feature point calculating section binarizes the image data to obtain a centroid of a consecutive component in which pixels are connected as a feature point, reverses the image data, obtains a centroid as a feature point from the reversed image data similarly, and adds them as a feature point of the image data. A features calculating section calculates a predetermined invariant based on the feature point containing the feature point obtained from the reversed image data, and calculates a hash value based on the predetermined invariant. A vote process section retrieves a hash table based on the calculated hash value, votes for a document of an index stored in association with the hash value, and accumulatively adds the vote. A similarity determination process section compares the number of votes calculated by the vote process section with a predetermined threshold value to determine a similarity.
