    摘要: An image retrieval method and apparatus independent of an illumination change are provided. The image retrieval method involves: inputting a query image; detecting an illumination color from the query image and converting the illumination color into a standard illumination color; extracting color information of the query image by using color descriptors; and retrieving a similar image by comparing the extracted color information with color information of a database which converts a variety of images into images of standard illumination colors and extracts and stores the color information of the images in advance. According to the method, without changing the structures of color descriptors or a similarity comparison using color information, an image retrieval independent of illumination changes is enabled by adding only a preceding step of standard illumination conversion.

    摘要: A method and an apparatus for converting the color temperature of metadata and a method and an apparatus for providing image metadata are provided. The apparatus for providing image metadata includes an input unit, an image metadata decoding unit, and an image color temperature converting unit. The input unit receives an input image, metadata corresponding to the color temperature of the input image, and color temperature information preferred by a user. The image metadata decoding unit calculates a color temperature corresponding to the metadata. The image color temperature converting unit converts the color temperature of the input image using the color temperature calculated by the image metadata decoding unit and the color temperature information preferred by a user.
