Digital image processing techniques for the detection and removal of cracks in digitized paintings or concrete structure

This document presents crack detection and removal techniques on digitized paintings. The crack detection technique proposed here can also be used to detect cracks in concrete structures by processing the digitized concrete images. Safety inspection of concrete structures is very important since it is closely related with the structural health and reliability. So, the development of crack detecting systems has been a significant issue. One of the objective of this document is to provide a method to develop an automatic crack detection system that can analyse the concrete surface and detect the cracks efficiently. The crack detection procedure proposed here is based on morphological bottom-hat transformation and finally crack filling is done by applying order static median filter using information of neighbourhood pixels.
