摘要： A target recognition system (200) includes a parallax calculator (203) to calculate parallax of a stereo image of an area ahead of the target recognition system (200) including two captured images acquired by a stereo imaging device (110A, 110B); a target candidate detector to detect a candidate set of recognition target areas (A, B, C, D, E, F) based on a luminance image of one of the captured images (110A, 110B) acquired by one of the imaging devices (110A, 110B); and a target recognition processor (206) to limit the candidate set of recognition target areas (A, B, C, D, E, F) detected by the target candidate detector (204) within a range of threshold values of characteristics in the candidate set of recognition target areas set in advance based on the parallax calculated by the parallax calculator (203) to extract and output the one or more recognition targets (A, C, E).

摘要： The object image detection device includes an image block generation unit to generate plural image blocks from the input image for detecting the object images, an image classification unit to determine whether each of the image blocks includes one or more of the object images by using one or more features of the object images, and acquire the image blocks including the object images to be object image candidates; and a detection unit to sequentially detect the object images from the object image candidates. The image classification unit acquires the object image candidates based on a relative positional relationship between the image blocks and already-acquired object image candidates.

摘要： An image-information obtaining unit (101) obtains image information. An image-component separating unit (102) separates the image information into luminance information and color information. An edge extracting unit (110) extracts edge information from the luminance information. A luminance-noise removing unit (105) removes noise from the luminance information. A color-noise removing unit (106) removes noise from the color information. An image-information synthesizing unit (107) synthesizes image information based on the edge information, the luminance information from which the noise is removed, and the color information from which the noise is removed.

摘要： An image-information acquiring unit (101, 801) acquires image information. A component separating unit (102) separates the image information acquired into luminance information and color information. A luminance-component-noise removing unit (105) removes noise from the luminance information using a first noise removing method. A color-component-noise removing unit (106) removes noise from the color information using a second noise removing method different from the first noise removing method used in the luminance-component-noise removing unit (105).

摘要： An image processing apparatus (200) includes a first memory, a data detector, a second memory, a third memory, and a determiner. The first memory stores a reference pattern including a plurality of reference basic units, each of which represents specific minimal information, is superposed on input image data, and represents specific entire information. The data detector detects a basic unit in the input image data based on the reference basic unit included in the reference pattern stored in the first memory. The second memory accumulates a number of basic units detected by the data detector. The third memory stores a predetermined value. The determiner determines whether the number of basic units detected by the data detector and stored in the second memory is equal to the predetermined value stored in the third memory.
