JPEG2000 Compatible Watermarking of Text in Images

In most of the image processing applications there is a maximum limit up to which an image can be compressed without adversely affecting the quality of the image to a great deal. In this paper, we propose a new watermarking scheme to embed text in images using an algorithm for finding the optimum bit plane that can be substituted from the image by the character bit plane. The maximum embedding capacity is kept as a function of minimum expected quality. This watermarking method is experimentally found to be highly robust against many image processing attacks including JPEG 2000 as it takes in to consideration both the lossy stages of JPEG 2000 during its implementation.
