Steganography is the art and science of hiding data into information. The secret message is
hidden in such a way that no one can apart from the sender or the intended recipient. The …

Thresholding is a direct and simple approach to extract different regions from an image. In its
basic formulation, thresholding searches for a global value that maximizes the separation …

The fuzzy technique is an operator introduced in order to simulate at a mathematical level
the compensatory behavior in process of decision making or subjective evaluation. The …

This paper proposes a novel edge detection method for both gray level images and color
images. The 3× 3 mask in the image is considered and two pixel sets S0 and S1 in the mask …

Video data is becoming an indispensable part of today's Big Data due to evolution of social
web and mobile technology. Content based video analysis has become crucial for video …

Data hiding is a technique that is embedding the secret message into the media. In 2010,
Chen et al.'s proposed a scheme combined the 'Canny'edge detector and fuzzy edge …

An edge detection is one of the most important tasks in image processing. Image
segmentation, registration and identification are based on edge detection. In the literature …

In this paper we discuss the application of two-dimensional linear cellular automata (CA)
rules with the help of fuzzy heuristic membership function to the problems of edge detection …

Image enhancement means to enrich the perception of images for human viewers. It can
reduce impulsive noise, sharpen the edges with the help of different image enhancement …

The principal component analysis (PCA) is one of the most successful techniques that have
been used to recognize faces in images. However, high computational cost and …
