摘要:
A method for recommending places to visit, included using a processor to provide the following steps: assembling a collection of images, wherein each image has first and second tags with the first tag corresponding to the location where the image was taken, and the second tag corresponding to subject matter of the image; clustering the images in response to the first tags into a plurality of locations; using the images in each location to produce at least one representative image of the location; using the second tags of images of each location to produce a list of representative keywords for each location; providing a query in the form of an image or subject matter, or both; and using the query in the form of an image to search among the representative images to recommend a location to visit, or using the query in the form of subject matter to search among the keywords to recommend a location to visit.
摘要:
A method of assigning semantic labels to images in a particular collection, includes acquiring seed labels for a subset of images; propagating the seed labels to other images according to a similarity metric; and storing the semantic labels, including both seed labels and propagated labels with the corresponding images.

A method of categorizing a social relationship between individuals in a collection of images to suggest a possible course of action, includes searching the collection to identify individuals and determining their genders and their age ranges; using the gender, and age ranges of the identifies individuals to infer at least one social relationship between them; and using at least one inferred social relationship to suggest a possible course of action.
摘要:
A method of processing a digital image, including the steps of: assigning belief values to pixels in the digital image, wherein the belief values are proportional to a belief that the pixels are associated with human skin; calculating a brightness adjustment amount based on a statistic of the pixels with belief values exceeding a threshold and the assigned belief values of the pixels; and applying the brightness adjustment amount to the digital image to produce a processed digital image having improved overall brightness.

A method for processing a digital color image for display and transmission includes the steps of (a) resizing the image to a lower display resolution to produce a display-sized image, (b) quantizing the display-sized image to a display palette with an error diffusion process to produce an error diffused image, (c) losslessly compressing the error diffused image to produce a compressed image having a particular file size, (d) comparing the file size to a maximum file size and if less than the maximum file size, transmitting the digital image to the display; (e) if the file size is greater than the maximum file size but less than a another predetermined file size, reducing the error diffusion rate by a predetermined amount in order to reduce the file size; and (f) if the file size is greater than the maximum file size and the predetermined file size, simplifying the resized image by reducing image detail to produce a simplified image and repeating the preceding steps on the simplified image.
摘要:
A method for detecting and correcting the orientation of a radiograph. The method generally includes the steps of accessing the radiograph; locating a region of interest in the radiograph; and using the located region of interest and a classifier to detect the orientation of the radiograph. In a preferred embodiment, the radiograph is preprocessed.
摘要:
A method for classifying radiographs. The method includes the steps of: accessing a radiograph; categorizing the radiograph into pre-determined classes based on gross characteristics of the radiograph, and recognizing the image contents in the radiograph.
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 method for scene classification of a digital image comprising the steps of: (a) extracting predetermined camera metadata tags from the digital image; (b) obtaining estimates of image class based on the extracted metadata tags; (c) obtaining estimates of image class based on image content; and (d) producing a final estimate of image class based on a combination of metadata-based estimates and image content-based estimates.
摘要:
A method improving scene classification of a sequence of digital images comprising the steps of: (a) providing a sequence of images captured in temporal succession; (b) classifying each of the images individually based on information contained in the image alone to generate a first image classification; and (c) imposing a pre-determined temporal context model on the sequence of images to generate a final image classification for each image in the sequence.
