Abstract: A method for processing a picture is disclosed. The method according to the invention comprises: segmenting the picture into a background layer and at least another layer; selecting a background template of color harmony for the background layer; determining one template of color harmony for each of the at least another layer from the background template of color harmony depending on the distance between the background layer and said at least another layer. processing the picture by mapping the colors of each segmented layer using the corresponding template of color harmony.

Abstract: A method for processing a video is disclosed. The method comprises: obtaining a type and an angle of a template for each picture of the video independently, each template defining a portion of harmonious color values; temporally filtering the types and angles over the video; processing each picture of the video, wherein processing the picture comprises mapping the colors of the picture into the template associated with the picture and defined by the filtered type and the filtered angle.

Abstract: The present invention generally relates to a method and apparatus for creating an harmony map of an image. It also relates to a method and apparatus for assessing the quality of an image. The invention also relates to a method and apparatus for assessing the quality of an image such that an assessment score of the image is obtained from a perceptual map of the image created from the previous method. As an interesting tool for content creator and in the goal of maximizing the artistic effect, the proposed method provides perceptual harmony-guided quality map as well as a score of disharmony of a picture without reference image. The method links two distinct subjects: perceptual quality metric and harmonious hue templates in order to provide new tools to content creator whatever the expertise level.

Abstract: A method for processing a video is disclosed. The method comprises: obtaining a type and an angle of a template for each picture of said video independently, each template defining a portion of harmonious color values; temporally filtering said types and angles over said video; processing each picture of the video, wherein processing the picture comprises mapping the colors of the picture into the template associated with said picture and defined by said filtered type and said filtered angle.

Abstract: The present invention generally relates to a method for creating a perceptual harmony map of an image, wherein it comprises: calculating a multi-resolution decomposition of the image, at each resolution level, for each harmonious color template, computing an optimal rotation angle and an harmony distance for the hue value associated with each pixel of the image at the resolution level, and computing a harmony distance map by weighting the sum of said harmony distances, calculating a contrast map and an entropy activity map obtaining a perceptual harmony map by integrating together the contrast map the entropy activity map and the harmony distance map, and obtaining a perceptual map by accumulating the perceptual harmony maps. The invention also relates to a method and apparatus for assessing the quality of an image.

Abstract: A method for processing an image is disclosed. The method comprises: determining regions of interest in the image; determining a color histogram of the regions of interest; selecting a first template that matches the color histogram in a set of templates, each template defining a portion of harmonious color values; and processing the image, wherein processing the image comprises mapping the colors of the image into a final template, the final template being the first template.

Abstract: A color video processing method is disclosed that comprises: marking out an object from a background in each frame of a sequence of frames of a color video, selecting at least two successive frames, determining a global color template from the backgrounds of the selected frames, for each selected frame and for colors of the marked out object, determining an harmonized color according to the global color template, in such a way that the harmonized color is closer to the global color template than the original color.

Abstract: A method for processing a picture is disclosed. The method according to the invention comprises: segmenting the picture into a background layer and at least another layer; selecting a background template of color harmony for the background layer; determining one template of color harmony for each of the at least another layer from the background template of color harmony depending on the distance between the background layer and said at least another layer. processing the picture by mapping the colors of each segmented layer using the corresponding template of color harmony.
