摘要:
A method of displaying an image with a display device having a set of defective display pixels includes receiving image data for the image. The method includes generating a first sub-frame and a second sub-frame corresponding to the image data. The method includes selecting a first position and a second position spatially offset from the first position, the first and the second positions selected based on positions of the defective display pixels and characteristics of a human visual system. The method includes alternating between displaying the first sub-frame in the first position and displaying the second sub-frame in the second position.

A system and method for enhancing scanned document images utilizes an estimated background luminance of a given digital image to remove or reduce visual “see-through” noise. The estimated background luminance is dependent on the luminance values of the edges pixels of detected text edges of the image. In one embodiment, the estimated background luminance is generated using only the edge pixels that are on the lighter side of the detected edges. In addition to the see-through removal, the system and method may further enhance the scanned document images by removing color fringes and sharpening and/or darkening edges of text contained in the images.
摘要:
Systems and methods of detecting and correcting redeye in an image are described. In one aspect, pixels of the input image are segmented based on projections of color values of the pixels onto two-dimensional thresholding planes. Candidate redeye pixel areas are identified in the input image based on the segmented pixels of the input image.

The disclosure relates to a system and a method for generating clothing feature data representative of at least one clothing feature of a piece of clothing being worn by the person in a set of images, and training a discriminative clothing classifier using the clothing feature data to provide a personal clothing model that corresponds to the piece of clothing. The personal clothing model can be used to identify additional images in which the person appears.

In one aspect, a metadata-based classification result is obtained based on metadata associated with an image. A histogram-based classification result is determined based on a histogram of intensity values derived from the image. The image is classified into a scene type class based on the metadata-based classification result and the histogram-based classification result. In another aspect, a first condition is applied on a first one of metadata associated with an image corresponding to a measure of amount of light received in capturing the image to obtain a first metadata-based classification result. A second condition is applied on a second one of the metadata corresponding to a measure of brightness of the image to obtain a second metadata-based classification result. The image is classified into a scene type class based on the first and second metadata-based classification results.

Systems and methods of detecting and correcting redeye in an image are described. In one aspect, the input image is sub-sampled to generate a thumbnail image, redeye pixel areas are detected in the thumbnail image. In another aspect, an input image having lines of pixels with original color values is processed. One or more redeye pixel areas corresponding to respective areas in the input image are detected. Each pixel in the input image corresponding to the detected redeye pixel areas is classified as a redeye pixel or a non-redeye pixel on a line-by-line basis without reference to pixels in adjacent lines. The original color values of pixels in the input image classified as redeye pixels are corrected.

Method, apparatus, and systems for extracting features from face regions and auxiliary identification regions of images are described. In one aspect, a face region containing at least a portion of a person's face is detected in an input image. An auxiliary identification region outside the face region is identified in the input image. Facial features characterizing the face region are determined. Auxiliary identification features characterizing the auxiliary identification region are calculated. An indexing datum is derived from the facial features and the auxiliary identification features. The indexing datum is stored in association with the input image.

An exemplary system for browsing videos comprises a memory for storing a plurality of videos, a processor for accessing the videos, and a video browsing user interface for enabling a user to browse the videos. The user interface is configured to enable video browsing in multiple states on a display screen, including a first state for displaying static representations of the videos, a second state for displaying dynamic representations of the videos, and a third state for playing at least a portion of a selected video.

Peteye is the appearance of an unnatural coloration (not necessarily red) of the pupils in an animal appearing in an image captured by a camera with flash illumination. Systems and methods of detecting and correcting peteye are described. In one aspect a classification map segmenting pixels in the input image into peteye pixels and non-peteye pixels is generated based on a respective segmentation condition on values of the pixels. Candidate peteye pixel areas are identified in the classification map. The generating and the identifying processes are repeated with the respective condition replaced by a different respective segmentation condition on the pixel values.

A method of displaying an image with a display device having at least one defective display pixel is provided. The method comprises generating first, second, and third sub-frames using image data for the image, information that identifies the at least one defective display pixel, a first pixel offset associated with the second sub-frame, and a sub-pixel offset associated with the third sub-frame, and alternating between displaying the first sub-frame in a first position, displaying the second sub-frame in a second position spatially offset from the first position according to the first pixel offset, and displaying the third sub-frame in a third position spatially offset from the first position and the second position according to the sub-pixel offset.
