摘要： As set forth herein, computer-implemented methods and systems facilitate detecting non-uniformities (e.g., streaks or other defects) in a scanned image, and correcting the non-uniformities while accounting for geometric distortion therein. For instance a scanned image may include a light streak (e.g., higher L* values than expected) down the page at a given distance from a page edge. Paper shrinkage may also cause the image to be magnified relative to the page. Correction values (e.g., L* knockdown values or the like) are generated to bring the non-uniform L* values down to a darker level. To account for the magnification of the image, the correction values are electronically registered to uniformity data for the page, and applied at the correct location to account for the magnification. The corrected image is then printed by a marking device.
摘要翻译：如本文所述，计算机实现的方法和系统便于检测扫描图像中的不均匀性（例如，条纹或其他缺陷），并且校正非均匀性，同时考虑其中的几何失真。例如，扫描图像可以包括距离页边缘一定距离的页面下的轻条纹（例如，比期望的更高的L *值）。纸张收缩也可能导致相对于页面放大图像。产生校正值（例如，L *击倒值等）以使不均匀的L *值下降到较暗的水平。为了考虑图像的放大率，将校正值以电子方式登记到页面的均匀性数据，并将其应用于正确的位置以考虑放大率。然后通过标记装置打印校正的图像。
