摘要： A system and method for determining image similarity. The method includes the steps of automatically providing perceptually significant features of main subject or background of a first image; automatically providing perceptually significant features of main subject or background of a second image; automatically comparing the perceptually significant features of the main subject or the background of the first image to the main subject or the background of the second image; and providing an output in response thereto. In the illustrative implementation, the features are provided by a number of belief levels, where the number of belief levels are preferably greater than two. The perceptually significant features include color, texture and/or shape. In the preferred embodiment, the main subject is indicated by a continuously valued belief map. The belief values of the main subject are determined by segmenting the image into regions of homogenous color and texture, computing at least one structure feature and at least one semantic feature for each region, and computing a belief value for all the pixels in the region using a Bayes net to combine the features. In an illustrative application, the inventive method is implemented in an image retrieval system. In this implementation, the inventive method automatically stores perceptually significant features of the main subject or background of a plurality of first images in a database to facilitate retrieval of a target image in response to an input or query image. Features corresponding to each of the plurality of stored images are automatically sequentially compared to similar features of the query image. Consequently, the present invention provides an automatic system and method for controlling the feature extraction, representation, and feature-based similarity retrieval strategies of a content-based image archival and retrieval system based on an analysis of main subject and background derived from a continuously valued main subject belief map.

摘要： A method for representing an image in terms of the shape properties of its identified segments of interest involves analyzing each segment of interest to automatically identify one or more of its perceptually significant components and then representing each perceptually significant component in terms of its shape properties, e.g., by means of Fourier descriptors. The image segment is then characterized as a composition of the shape properties of its perceptually significant components. By repeating the foregoing steps, the image is represented as a composition of its characterized segments. This technique can then be used to archive and retrieve images based on the shape properties of identified segments.

摘要： A method for retrieving digital patterns similar to a query pattern operates by generating representations of each digital pattern in terms of one or more color invariant properties; storing and organizing the patterns and their representations in a database; and searching the database by reference to the representations to identify and retrieve patterns similar to the query pattern. A preferred color invariant property is an edge property of the digital patterns. A web-based pattern registration and searching architecture enables on-line pattern search and selection utilizing a variety of pattern representations and similarity techniques, including the edge property based system described above.

摘要： A user preference for a desired image is determined by using one or more examples and counterexamples of a desired image in order to define the user preference. A relative preference of a user for one or more image components or one or more depictive features is automatically extracted from the examples and counterexamples of the desired image. Then, a user subjective definition of a desired image is formulated using the relative preferences for either the image components or the depictive features.

摘要： An image is automatically assessed with respect to certain features, wherein the assessment is a determination of the degree of importance, interest or attractiveness of the image. First, a digital image is obtained corresponding to the image. Then one or more quantities are computed that are related to one or more features in the digital image, including one or more features pertaining to the content of the digital image. The quantities are processed with a reasoning algorithm that is trained on the opinions of one or more human observers, and an output is obtained from the reasoning algorithm that assesses the image. More specifically, the reasoning algorithm is a Bayesian network that provides a score which, when done for a group of images, selects one image as the emphasis image or the appeal image. The features pertaining to the content of the digital image include people-related features and/or subject-related features. Moreover, additional quantities may be computed that relate to objective measures of the digital image, such as colorfulness and/or sharpness.

摘要： A method of generating captions or semantic labels for an acquired image is based upon similarity between the acquired image and one or more stored images that are maintained in an image database environment, where the stored images have preexisting captions or labels associated with them. The method includes the steps of: a) acquiring an image for evaluation with respect to the stored images; b) automatically extracting metadata from the acquired image without requiring user interaction in the image database environment; c) automatically selecting one or more stored images having metadata similar to the extracted metadata, thereby providing selected stored images with metadata similar to the acquired image; and d) generating captions or labels for the acquired image from the preexisting captions or labels associated with the selected stored images.
