Abstract:
1. A method for automatic removal of vertical streaks, the method comprising the steps of: receiving image data pertaining to pixels of an image; processing the image data to determine, in consideration of accumulative information pertaining to the pixels, whether the image data for a group of pixels is sufficiently different from the image data for neighbor pixels to designate pixels of the group of pixels as non-homogenous; and designating the non-homogenous pixels as parts of a non-homogenous streak depending upon locations of the non-homogenous pixels within the image; wherein the image is divided into segments; and wherein the non-homogenous pixels are designated as parts of a non-homogenous streak if the non-homogenous pixels are associated with a common optical sensor and occur a sufficient number of times within at least one of the segments.
