Localization and text sequence restoration using noise pixels in binary document image watermarking
bstract. We propose a new method for tamper localization and estoration using noise pixels in binary document images. For such mages, it is difficult to find a sufficient number of low-distortion pixls in individual blocks with blind detection property. Also, a percepual watermark cannot be embedded in white regions of the docuent image, making such regions insecure against hostile attacks. n e...
متن کاملDocument image restoration using binary morphological filters
This paper discusses a method for binary morphological lter design to restore document images degraded by subtractive or additive noise, given a constraint on the size of lters. With a lter size restriction (for example 3 3), each pixel in output image depends only on its (3 3) neighborhood of input image. Therefore, we can construct a look-up table between input and output. Each output image p...
متن کاملRestoration in Secure Text Document Image Authentication Using Erasable Watermarks
In this paper, we propose a new restoration method for electronic text document images using erasable watermarks. In restoration application, finding sufficient number of low-distortion pixels in a block to embed sufficient information bits and their blind detection is difficult. In the proposed method, an erasable watermark is embedded in each block of a text document image for restoration of ...
متن کاملSecure Tamper Localization in Binary Document Image Authentication
In this paper, we propose a novel method for secure tamper localization in binary document images using erasable watermarks. For binary images, watermarking with pixel flipping approach is a difficult task, because it can bring noticeable visual distortion. In localization, finding sufficient number of low-distortion pixels in a block to embed the cryptographic signature and their blind detecti...
متن کاملRobust Binary Image Watermarking Using DCT
This paper examine the workability of watermark embedding in the discrete cosine transform (DCT) domain for binary images. Watermark embedding is quite difficult for binary images due to its prevalence and compactness. This presents a watermarking algorithm for binary images. A post-embedding binarization is a necessary step to ensure that the watermarked image is still a binary image for frequ...
