Comparative Analysis of Normalization based Image Watermarking Techniques

Comparative Analysis of Normalization based Image Watermarking Techniques

This paper presents a comparative study of watermarking schemes. The embedding of watermark is performed after the image normalization. By normalization process the normalized image achieves invariance properties against geometric attacks which include rotation, scaling and translation of an image. Watermarking is done using five methods DCT Zigzag, DCT blocks, DWT, Zernike transform, SVD-DCT. ...

Attribute Normalization Techniques and Performance of Intrusion Classifiers: A Comparative Analysis

Network traffic have several attributes with different range of values. These attributes can be qualitative or quantitative in nature. Attributes with large values significantly influence the performance of intrusion classifier making it bias towards them. Attribute normalization eliminates such dominance of the attributes by scaling the values of all the attributes within a specific range. The...

Comparative Performance Analysis of Segmentation Techniques

The study presented in this article focuses on comparative analysis of Segmentation techniques. Segmentation techniques are applied to extract Region of Interest (ROI) from medical images obtained from different medical scanners such as Ultrasound, CT or MRI. Global thresholding, Adaptive Thresholding, Region grow and Active contour using level set techniques has been used in the proposed segme...
