摘要： An apparatus, method and an image quality guide document are disclosed. The method includes, for at least one image in a set of images undergoing image enhancement, identifying image quality-related features for the image based on enhancements being applied to the image, identifying image content-related features based on content of the image, determining a content-based degradation of the image based on the identified image quality-related features and image content-related features, and generating a thumbnail of the image. The method further includes generating an image quality guide document for the set of images in which at least one of the thumbnails is associated with a respective text description that is based on the determined content-based degradation.

摘要： A system and method are provided for modeling a chromatic object, such as an image. For a set of colors of a chromatic object that are expressed as color values in a perceptual color space, the method includes optimizing a convex objective function which is a log likelihood function of a combination of weighted kernels centered on each color in the set over each of the other colors in the set. A number Nc of weighted kernels in the optimized function which each have a weight which is at least greater than 0 is identified. The chromatic object is modeled with a mixture model in which the complexity of the model is based on the identified number Nc.

摘要： A system and a method are disclosed for developing a query. The system includes a display device for displaying elements, such as images, textures, color palettes, ad textual elements, which are selectable as query elements for forming a query. A physical space is provided on the display in which a physical object can be positioned. At least one physical object is positioned in the physical space, which is recognized by the system as having an identifier stored in memory to which a query can be linked. A sensor is provided for detecting a physical manipulation of the physical object in the physical space which represents absorbing a query element into a query. A query generator generates a query based on the absorbed query element. The query is thus associated in memory with the identifier for the recognized object. In this way, several physical objects can be manipulated on the display device, each one corresponding to a respective, single query.

摘要： An apparatus and method for detecting a region of interest in an image are disclosed. Image representations for a set of images that have been manually annotated with regions of interest are stored, along with positive and negative representations of each image which are similarly derived to the image representations except that they are based on features extracted from patches within the region of interest and outside it, respectively. For an original image for which a region of interest is desired, the stored information for K similar images is automatically retrieved and used to train a classifier. The trained classifier provides, for each patch of the original image, a probability of being in a region of interest, based extracted features of the patch (represented, for example, as a Fisher vector), which can be used to determine a region of interest in the original image.

摘要： A method and a system for forming an inset image are disclosed. The method includes identifying a region of interest in an original image. An inset is generated, based on the region of interest. A region of low interest is identified in the original image. The inset is applied to the region of low interest to form an inset image. The region of interest is scaled differently from the inset in the inset image. The method can proceed automatically or substantially automatically, without the need for significant user input.

摘要： Automated font mapping is performed for one or more document fonts of a document to map the one or more document fonts to at least one replacement font. The font mapping is limited by at least one document-specific font mapping limitation. The document is rendered using the at least one replacement font. The automated font mapping may include performing a constrained optimization of an objective function measuring similarity of the one or more document fonts and the corresponding mapped at least one replacement font, the constrained optimization being constrained by at least one constraint embodying at least one document-specific font mapping limitation. The automated font mapping may include selecting a subset of the set of fonts available for the rendering based on the at least one document-specific font mapping limitation, and performing the optimization respective to the selected subset of the set of fonts available for the rendering.

摘要： A system and method for categorizing color palettes are provided. A taxonomy for a particular type of achromatic entity, such as emotions, is generated and populated with a list of terms. Natural language terms extracted from annotated color palettes are associated with the corresponding achromatic entity categories in the taxonomy. Features are extracted from the color palettes. The features, together with the category information, are used to train a classifier which is then able to assign achromatic entities to palettes outside the training set, based on extracted features.
