A Hybrid BPS-DCT Based Digital Image Watermarking Technique
Abstract: In this paper a hybrid algorithm using Bit Plane Slicing (BPS) and Discrete Cosine Transform (DCT) for digital image watermarking is proposed. There are two main requirements for digital image watermarking: imperceptibility and robustness. Imperceptibility is measured by Peak Signal to Noise Ratio and robustness is obtained by correlation between original and extracted watermark image. In this algorithm an image and watermark is first sliced into its bit planes using …

Hamming Coded Watermarking for Image Authentication and Evaluation by Image Transmission using Digital Modulation Schemes
Abstract: Proposed watermarking scheme for image authentication and tampered detection. Here, image encoded with a message is generated, after embedding watermark symbol within a colour cover image. The message information is converted to hexadecimal values from its ASCII representation. To encode this and embed the watermark, (7, 4) Hamming code is used. These bits will be divided into 7-bit blocks which will spread across the width of the image. The proposed …

Image Segmentation
Abstract: In computer vision, image segmentation is the process of partitioning a digital image into multiple segments (sets of pixels, also known as super-pixels). The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyze.[1][2] Image segmentation is typically used to locate objects and boundaries (lines, curves, etc.) in images. More precisely, image segmentation is the process of …
