    • A technique of editing a digital image provides for the automatic removal of blotchy areas. From a user interface of a computer system, a user of the computer system identifies a location of a blotchy area to be removed in the digital image in response to prompting by the user interface. Based on the location provided by the user, the technique automatically determines the location of the blotchy area. Attributes of pixels comprising the digital image in a neighborhood around the blotchy area are automatically collected, while excluding the pixels comprising the blotchy area. The corrupted values of the pixels of the blotchy area are replaced with values derived at least in part from the attributes of the neighboring pixels Several different embodiments are described with various degrees of automation, including one embodiment in which all blotches of a character similar to the one selected by the user are automatically identified and removed.
    • 编辑数字图像的技术提供了自动去除斑点区域。 根据计算机系统的用户界面,计算机系统的用户响应于用户界面的提示,识别要在数字图像中移除的斑点区域的位置。 基于用户提供的位置,该技术自动确定斑点区域的位置。 在包括斑点区域的像素的排除的同时,自动地收集包含在斑点区域附近的附近的数字图像的像素的属性。 斑点区域的像素的损坏值被至少部分地从相邻像素的属性导出的值代替。以不同的自动化程度来描述几个不同的实施例,包括一个实施例,其中所有类似于 用户选择的一个将被自动识别和删除。
