    摘要: What is disclosed is a novel system and method for content-aware resizing of a digital image. To take advantage of the characteristics of various importance maps generated for the image using different operators such as, for example, gradient, entropy, probabilistic operators, and the like, a method is provided herein for combining generated pixel importance maps. The present method uses a weighted combination of pixel importance maps—one corresponding to each image operator, to produce a hybrid map for all the image. The image can then be resized based on this hybrid map. The present method provides a high degree of image resizing flexibility and has broad applicability across differing classes of images and applications such as display, printing, packaging, and other document image processing software performing document layout, image personalization, and the like.

    摘要: Disclosed is a method and system for compensating for printer cross-process nonuniformity. The method and system provide a means to offset a cross-process uniformity profile associated with an image output device, such as a printer, where process direction noise is measured and the cross-process uniformity profile is adjusted accordingly to provide a better representation of the image output device cross-process uniformity profile.
