Abstract
An imaging system and method compensate lens distortion for an image. The system identifies lens distortion among one or more distortions, and extracts a Point Spread Function (PSF) for the lens distortion. Additionally, the system extracts a total PSF associated with total distortion in the input image and separates a PSF for the lens distortion from the total PSF. The system updates the pre-estimated kernel with the PSF of the lens distortion when a rank of the PSF matches with the predefined rank value, and one or more difference values determined between one or more singular values of the PSF and one or more singular values of the pre-estimated kernel is within a pre-defined threshold limit. Thus, quality of each output image obtained from the system may be maintained irrespective of error introduced by wear and tear on the lens of the system over a period of time.
