摘要： Systems and methods according to the present invention provide techniques to automatically crop an image to a desired size. Automating the cropping process, while at the same time providing a high quality, cropped image, can be accomplished by employing a comprehensive approach that includes one or more of contextual cropping (e.g., basing cropping decisions on elements within the image to be cropped itself), training the cropping mechanism (e.g., using previously cropped versions of the same image or related images) and multiple operational modes (e.g., selecting one of a plurality of different cropping techniques for cropping a particular image).
摘要翻译：根据本发明的系统和方法提供了将图像自动裁剪成所需尺寸的技术。自动化裁剪过程，同时提供高质量的裁剪图像可以通过采用包括一个或多个上下文裁剪（例如，基于裁剪图像内的元素的裁剪决策本身）的综合方法来实现，训练裁剪机制（例如，使用相同图像或相关图像的先前裁剪的版本）和多种操作模式（例如，选择用于裁剪特定图像的多种不同裁剪技术之一）。

摘要： Embodiments of the present invention recite a system and method for creating an editable template from a document image. In one embodiment of the present invention, the spatial characteristics and the color characteristics of at least one region of a document are identified. A set of characteristics of a graphic representation within the region are then determined without the necessity of recognizing a character comprising the graphic representation. An editable template is then created comprising a second region having the same spatial characteristics and the same color characteristics of the at least one region of the document and comprising a second graphic representation which is defined by the set of characteristics of the first graphic representation.

摘要： Systems and methods according to the present invention provide techniques to automatically insert an object from one image into a region of another image. The systems and methods require little or no user interaction to allow efficient re-use and updating of existing images, presentations, documents and the like. An object and a container region are identified. Feasible placement location(s) within the container region for the object, as well as an associated scale factor, are determined. If multiple feasible placement locations are identified for a particular scale factor, then one is selected based upon predetermined criteria. The object can then be inserted into the container region and the resulting composite image stored or, alternatively, parameters can be stored which enable object insertion at a subsequent processing step.
