摘要： A system and method for automatically altering an image having pixels is disclosed. An image is segmented into regions and various features of the regions are extracted and used to calculate a confidence factor, or belief value, that a particular region is a main subject of the image. The belief values are assembled into a belief map that is used to define how pixel values are to be altered. Various color and appearance values of the pixel are altered in a predetermined way to emphasize the main subject of the image. The emphasis is applied in a binary fashion or as in a gradient of values. Either the main subject can be emphasized, or the secondary or background subjects can be de-emphasized. The system can be implement on a variety of computer systems.

摘要： A method is disclosed for providing photofinishing services for images having a main subject and background, comprising the steps of producing a digital image of a customer's photographic image; producing a main subject belief map from the digital image; employing the main subject belief map to produce a modified digital image; producing a print of the digital image; producing a print of the modified digital image; and delivering both prints to the customer. The step of employing the main subject belief map to produce a modified digital image includes zoom and crop steps that maintain a main subject within a resulting cropped image. The step of employing the main subject belief map to produce a modified digital image may include a subject emphasizing step. The emphasizing step may include the step of maintaining the main subject in color and the background in black and white, the step of altering the background by reduced brightness to produce a spotlight effect on the main subject, and/or the step of altering the background with reduced sharpness. The step of employing the main subject belief map to produce a modified digital image may include the step of altering pixel values that are a part of the main subject and/or altering pixel values that are a part of the background.

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 and computer program/system for cropping a digital image includes inputting a belief map of a photographic image, (a belief value at a location in the belief map indicates an importance of a photographic subject at the same location in the photographic image), selecting a zoom factor and a crop window, clustering regions of the belief map to identify background portions, secondary portions and main portions, positioning the crop window such that the crop window is centered around a main portion having a highest belief value, moving the crop window such that the crop window is included completely within the image, moving the crop window such that a sum of belief values is at a maximum, and cropping the image according to the crop window.
