METHODS, APPARATUS AND PROGRAM STORAGE DEVICE FOR REMOVING SCRATCH OR WIRE NOISE, AND RECORDING MEDIA THEREFOR

摘要

Methods and apparatus for removing scratch and wire noisefrom digitized images handle the difficult case of non-uniformlyshaded images which is the common situation in real applications.The methods and apparatus also utilize a soft edge noise mask toallow a smoother blending of the reconstructed noise and the imagearound the noise, wire noise removal from digitized images whereina scratched portion of a digitized image which requires repair ornoise removal is identified and a binary mask is generated whichdistinguishes the defined scratched portion from the other portionsof the digitized image. The methods and apparatus utilize both thespatial and frequency domains to effectively reconstruct manycontiguous noisy pixels, reconstruct textures even when they arelarge featured, maintain sharpness and maintain continuity offeatures across a noisy region. A set of instructions for executingthe methods is contained in a program storage device. Also, arecording media contains digital data generated using the methods.
