Method for automatic removal of vertical streaks by modifying image data associated with non-homogenous image elements

A method for automatic removal of vertical streaks involves a comparison between image data for a pixel and its neighbor pixels to determine whether the pixel is non-homogenous. In a preferred method, the comparison employs an adaptive threshold against which a difference between the pixel and its n...

Zusammenfassung:A method for automatic removal of vertical streaks involves a comparison between image data for a pixel and its neighbor pixels to determine whether the pixel is non-homogenous. In a preferred method, the comparison employs an adaptive threshold against which a difference between the pixel and its neighbor pixels is compared, with the adaptive threshold taking into account accumulative information pertaining to pixels generated by a common optical sensor element. A preferred method also includes the step of considering locations of non-homogenous pixels in the image to determine whether the image data associated with the non-homogenous pixels needs to be changed or modified. A preferred method also includes the step of associating the non-homogenous pixels with different image data.
