    摘要： A technique is provided for classifying images in a library (1) for subsequent selective retrieval. Each library image is segmented (2) into a plurality of coherent regions. Each of the regions is analysed in respect of a plurality of visual properties, each of which is ascribed a number according to the value of the visual property. The property numbers are then compared (4) with bands of the available property range and a computer-readable character, such as a letter of the alphabet, is ascribed to each of the property values. The characters are then arranged (5) in a predetermined order to form a region character string. The strings for each region are then indexed (7) to form an index (8) of the images by region character string. For image retrieval, a target image (10) is analysed in the same way to form region character strings which are then supplied to a text retrieval system (12) for detecting matches with entries in the index (8). Library images having matching regions are retrieved from the library (1).

    摘要： An image browsing apparatus capable of calculating color temperature of an image and browsing the image based on the color temperature, and a method of browsing an image are provided. The image browsing apparatus includes a data storage unit for storing a plurality of image data; a color temperature calculator for calculating the color temperature of each image and storing the calculated color temperature in the data storage unit; a command input unit for inputting an image browsing mode; and a color temperature browser for classifying images corresponding to the browsing mode using the color temperature as an image search condition and then, browsing the classified images. The method of browsing images includes determining the color temperature of an input image when a browsing mode is input; and browsing images when the color temperature falls within the color temperature range of the browsing mode.

    摘要： The present invention relates to methods and apparatus for quantizing a bin value of a histogram. A method according to the present invention can include dividing a bin value into N+1 regions using N threshold values; and dividing and quantizing each respective one of the divided regions uniformly and with greater resolution to yield smaller divisions as a region is nearer to zero. For example, the bin value can be divided into six regions using five non-uniform threshold values (th1, th2, th3, th4 and th5), which can be set to 0.000000001, 0.037, 0.08, 0.195, and 0.32, respectively. A first region (

    摘要： The present invention discloses a method for setting a dominant color using a spatial coherency in order to improve performance of an image search function, describing an image region based on several dominant colors, a frequency of each dominant color, and a spatial coherency (SC) of the dominant color. In the method according to the present invention, the spatial coherency is non-uniformly quantized based on a predetermined threshold. According to one embodiment of the present invention, the spatial coherency (SC) is ranged from 0 to 1 and the threshold is set to 0.70.

    摘要： A method (Img_Class) for associating with a digital image (Img RGB ) a class of a plurality of predefined classes characterized by respective models. The method comprises the following phases:

    dividing (Reg_Detect) the digital image pixel by pixel into one or more regions belonging to a set of predefined regions that differ from each other on account of their type of content, the division being effected by establishing whether or not a pixel of the image belongs to a respective region on the basis of an operation of analyzing the parameters this pixel, the analysis operation being carried out by verifying that the parameters satisfy predefined conditions and/or logicomathematical relationships of belonging to the respective region,
    acquiring (f 1 ) from the digital image divided into regions (Img Reg ) information regarding the regions that are present in it,
    comparing (Cmp) this information with at least one model characterizing a respective class of said plurality,
    associating (SetCL 1 ) with the digital image a class (I_Class) on the basis of the comparison phase.
