The Correction Methods of Morphology on Uneven Lighting Pavement Image

Abstract:

The pavement image collected under the natural light, often exist the uneven background grayscale , it affects the subsequent image processing. For this reason, this paper puts forward an image correction method that is based on the morphology. The method get the uneven background light image through the morphology opening operation for the original image , then subtracting the background from the original image and eliminate the influence of the uneven background. Due to the difference image has the low contrast ratio, this paper improves the contrast ratio of the difference image by the contrast enhancement algorithm. Experimental results show that the method can correction the uneven lighting image , and improve the contrast ratio of the image. The Project was Supported by the Special Fund for Basic Scientific Research of Central Colleges,Chang'an University (CHD2010ZY011)
