Method to detect previous sharpening of an image to preclude oversharpening
摘要：
Disclosed are methods of processing digital images to detect previous sharpening of the images by sequentially examining characteristics of individual pixels within the image and the neighborhood of pixels immediately surrounding the individual pixels. Detection of previous sharpening allows detrimental oversharpening to be avoided. Also disclosed are methods of determining whether a digital image has been previously sharped and, based upon that determination, selectively sharpening the image.
摘要（中）：

公开了处理数字图像以通过顺序检查图像内的各个像素的特征和紧邻各个像素的像素的邻域来检测图像的先前锐化的方法。 检测以前的磨削可以避免有害的过敏。 还公开了确定数字图像是否已经被预先锐化的方法，并且基于该确定来选择性地锐化图像。
