METHOD FOR CONTRAST MATCHING OF MULTIPLE IMAGES OF SAME OBJECT OR SCENE TO COMMON REFERENCE IMAGE

摘要

PPROBLEM TO BE SOLVED: To provide such image processing that can be used in various types of imaging systems in order to reducing the irregularities of brightness and contrast between different images. PSOLUTION: An imaging system (10) includes an image forming device (26) for generating a first image and a second image and a controller (28) coupled to the image forming device (26). The controller (28) receives the first image and the second image. In the method the controller (28) generates an image ratio of the first image and the second image, regularizes the image ratio of the second image with respect to the first image to form a regularized image ratio and filters the image ratio to form a filtered ratio. The controller (28) then multiplies the second image by the filtered ratio to form an adjusted image. PCOPYRIGHT: (C)2003,JPO
