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 is provided for reducing occurrence of color fringe errors occurred at the time of carrying out a color filter interpolation and reducing degradation of an image quality. Interpolation of a G channel value in a pixel of the color filter having only R or B channel values is carried out such that a similarity measured between channels based on interpolation results in horizontal and vertical directions are measured, and the G channel interpolation is carried out in a direction where the measured similarity becomes the maximized. However, when the reliability of the measured similarity becomes poor, a final G channel interpolation is carried out using a weighted average value using similarity information of each direction and interpolation results of the horizontal and vertical directions.

The apparatus for estimating illuminant chromaticity includes an image input unit for receiving a color image, a highlight detector for extracting highlight regions from the color image, a highlight parameter calculator for mapping the highlight regions to chromaticity coordinates and calculating geometric presentation parameters of the shape of the distribution of chromaticity coordinates, a perceived illumination illuminant chromaticity estimator for estimating illuminant chromaticity in the color image using a perceived illumination estimate scheme, and a correct chromaticity calculator for selecting a predetermined number of geometric presentation parameters near the illuminant chromaticity estimated by the perceived illumination illuminant chromaticity estimator among the geometric presentation parameters and calculating final illuminant chromaticity using the selected geometric presentation parameters. The method for estimating illuminant chromaticity using perceived illumination and highlights is used for estimating illuminant chromaticity from a color image. This method, which is a combination of two kinds approaches, a perceived illumination estimate scheme and a highlight estimate scheme, considers the characteristics of highlights based on stable illuminant chromaticity estimated from perceived illumination, thereby improving accuracy.
