The invention concerns a device for multimedia data retrieval. The multimedia data is associated with an active component. The device for multimedia retrieval being characterized in that, depending on an external event, some of the active components trigger an action that make the user aware of the multimedia data associated with said active components.

Method and device for multimedia data retrieval

A method and an arrangement for an improved outlier detection for color mapping. Spatial neighborhoods of feature points are used for outlier detection. For this purpose, Geometric Feature Correspondence neighborhoods of an initial color-corrected test-image and a reference image are compared in a neighborhood comparator.

Device and method for multimedia data retrieval

A method for image processing of digital image pixels. Pixels are preferably filtered spatially and dithered, and the value for at least one color component is bit reduced. The space freed by the bit reduction is used to allocate a look-up table selection bit that indicates which look-up table (LUT), from a plurality of small LUTs partitioned from a bigger LUT, should be used for the color transform. The transformed pixels are then selected according to the used LUT, format converted and output. The invention, which also covers an apparatus and a pre-processing module, enables an apparatus with a LUT to be used both as a single full-rate LUT apparatus and as a lower-rate n smaller LUT apparatus.

Method and apparatus for color transformation by addressing a look-up table

The spatial frequency analysis contained in the compressed image is used not only for decompression of images but also for the selection of an appropriate gamut mapping algorithm. Computation resources are then saved because no specific spatial frequency analysis is required for the selection of an appropriate gamut mapping algorithm.

Method of processing of compressed image into a gamut mapped image using spatial frequency analysis

In accordance with an exemplary embodiment, a method is provided to generate a color look up table for multiple images. The method includes selecting color points from a first image. The first color points comprise weak image texture. The method also includes identifying feature points in a spatial neighborhood of each first color point. Additionally, the method includes identifying feature points from a second image. The second feature points correspond to the first feature points. The method also includes determining a color points in the second image. The second color points correspond to the first color points, and are determined using a spatial interpolation of the first plurality of color points from the first plurality of feature points and then applying the obtained spatial interpolation to the second plurality of feature points. Further, the method includes generating the color lookup table.

To describe the actual color gamut, a hierarchical structure is proposed which comprises, from bottom to top: Such a Gamut Boundary Information may be notably used for gamut mapping operations. Among advantages of the invention, are flexibility and adaptation to available memory and bandwidth capabilities.

Method for describing an actual color gamut of a color device or of a color content

Method of mapping source colors from a source color device having an actual source gamut that is represented by a source convex (gamut boundary descriptor) and a source non-convex into target colors for a target color device having an actual target gamut that is represented by a target convex and a target non-convex, comprising,

The invention relates to a method and a device for detecting the orientation of an image in a set of images. All images in this set of images contain at least one similar object. The method proposes to choose one image in this set of images as being a reference image. The orientation of the other images is detected based on the orientation of this reference image.

Method and device for detecting the orientation of an image

The invention relates to a processing method of a sequence of images comprising image points each of which is associated with a color component. The method comprises a processing step of at least one image of the sequence from reference images, the processing step being adapted to reduce the flicker effects. According to the invention, the reference images are selected according to the following stages:

A colour quality control device adapted for use in a system for colour correction of an image to be reproduced on at least one reproduction device that is calibrated by a reproduction forward transform. The system also comprises a colour correction device adapted to correct at least one colour in the image. The colour quality control device comprises a false contour detection unit that uses information from the reproduction forward transform to decide if a contour in the image is a false contour introduced by the transform. This facilitates the operator's work during colour correction. A system and a method are also provided.
