In this paper a novel adaptive filtering scheme for impulsive noise removal in color images is presented. The noise detection algorithm is based on the concept of aggregated distances assigned to the pixels belonging to the filtering window. The value of the difference between the accumulated distance assigned to the central sample and to the pixel with the lowest rank, serves as an indicator o...

This paper presents a neural network approach to image color quantization and hence image data compression. Self-organizing feature maps form a basis for general vector quantization and this is applied to the tristimulus color values of image pixels. For image telecommunication systems such as videoconferencing, it Is desirable to constrain the encoder to a single pass of the image using the no...

In 2001, with the nonlinear l┙┚ space (Ruderman et al., 1998), Reinhard et al. (Reinhard et al., 2001) introduced a method to transfer colors between two color images. The goal of their work was to make a synthetic image take on another image’s look and feel. Applying Reinhard’s statistical color transfer strategy, Toet (Toet, 2003) subsequently developed a color-transfer-based image fusion alg...

|Image halftoning converts a high-resolution image to a low-resolution image, e.g. a 24-bit color image to a three-bit color image, for printing and display. Vector error di usion captures correlation among color planes by using an error lter with matrix-valued coe cients. In optimizing vector error lters, Damera-Venkata and Evans transform the error image into an opponent color space where Euc...

Retrieval of an image is a more effective and efficient for managing extensive image database. Content Based Image Retrieval (CBIR) is a one of the image retrieval technique which uses user visual features of an image such as color, shape, and texture features etc. It permits the end user to give a query image in order to retrieve the stored images in database according to their similarity to t...

In digital cinema, an image goes through many types of processes like scanning, mastering, and digital intermediate. Among them, the digital intermediate process plays a central role because it determines the final color of an image. It edits and changes the colors of the images. However, some color distortions such as color bleeding are generated when editing and changing local colors in an im...
