摘要： A method of transforming the color appearance of a plurality of digital images includes receiving a plurality of digital images from a capture medium wherein each digital image includes a plurality of pixel values relating to at least three basic colors; calculating a color correction transform by using a non-linear adjustment that is independent of the digital images and which corrects an under-exposure condition as a function of the capture medium; and a linear functional relationship dependent upon the pixels of the basic colors, the linear functional relationship defining an exposure-level-dependent estimate of gray corresponding to the photographic response of the capture medium; and using the color correction transform to modify the pixels of the plurality of digital images wherein the pixels within a digital image are transformed with varying degrees of color modification as a function of exposure.

摘要： A computer implemented method for modifying a digital image, comprising loading the digital image into an electronic memory accessible by the computer, identifying an individual region in the digital image that includes a human face, determining a padding amount based on a size of the individual region, digitally defining a padded region including padding borders of the individual region by the padding amount. The padding amount is based on a ratio of the size of the individual region to a size of the digital image.

摘要： Correction of color defects in a pupil represented in a digital image is disclosed. For example, a location in the pupil within the digital image is identified, and a target color to be corrected is computed based at least upon an analysis of pixels within a first region in which the location resides. Defect pixels in a second region in which the location resides are identified, the defect pixels being identified as having a pixel color similar to the target color. The defect pixels are color-corrected. For pupils that appear all white, appropriately configured pupil images are inserted therein.

摘要： A method for determining an impact score for a digital image includes providing the digital image wherein the digital image includes faces; using a processor to determine an image feature for the faces; using the processor to compute an object impact score for the faces, wherein the object impact score is based at least upon one of the determined image features; weighting the object impact score for the faces based on one of the determined image features for a face; using the processor to compute an impact score for the digital image by combining the weighted object impact scores for the faces in the image; and storing the computed impact score in a processor accessible memory.

摘要： A computing system storing a digital image and identifying a region in the digital image that includes a human face. A padding amount is determined based on a size of the individual region. The padding amount can be determined based on a width of the individual region and a size of the digital image. A head pose and eye gaze direction contained in the individual region can be used to select a direction for extending borders of a cropped region of the image.
