£6.25 Preview RemoveDigital Watermarking
Introduction 1.1 Digital Watermarking Watermarking techniques are usually preferred for copyright ownership declaration, creator/authorship declaration, copyright violation detection (fingerprinting function), copyright violation deterrence, copy control, media authentication, and media data integrity functions. They are also devised for variety of media viz., text, digital audio, digital image and digital video. 1.2 Spread Spectrum (SS) Watermarking 1.2.1 Spread Spectrum Spread Spectrum techniques for watermarking purposes have aroused a lot of interest in today because of it’s using in Steganography. Generally the message use to watermark is a narrow band signal compared to the wide band of the cover image. Spread spectrum techniques applied to the message allow the frequency bands to be matched before transmitting the message (Watermark) through the covert channel (image). Furthermore, high frequencies are relevant for the invisibility of the watermarked message but are inefficient as far as robustness is concerned, whereas low frequencies are of interest with regards to robustness but are useless because of the unacceptable visible impact. Spread spectrum can reconcile these conflicting points by allowing a low energy signal to be embedded in each one of the frequency bands. Spread spectrum techniques also offer the possibility of protecting the watermark privacy using a secret key to control a pseudo noise generator. 1.2.2 Mathematical form of SS Watermarking encoding and Decoding Cox proposed a watermarking scheme that is based on the spread spectrum (SS) communication .In this scheme, the discrete cosine transform (DCT) is performed on a whole image and then the watermark is embedded in a predetermined range of low frequency components as shown in Figure 2.1. The embedded watermark signal consists of a sequence of real numbers that are normally distributed and it is scaled according to the signal strength of the frequency components. It is a simple watermarking scheme with perceptual weighting consideration.
£4.38 Preview RemoveArithmetic and Pre-Algebra
Arithmetic and Pre-Algebra are foundational areas of mathematics that introduce basic mathematical operations and prepare students for more advanced topics like algebra and geometry. Arithmetic involves the study of numbers and basic operations—addition, subtraction, multiplication, and division. It focuses on understanding how numbers work and how to perform calculations with them, such as adding fractions, working with decimals, and calculating percentages. These skills are essential for daily life and serve as the building blocks for more complex mathematical concepts. Pre-Algebra acts as a bridge between arithmetic and algebra, introducing students to the concepts and skills needed to understand algebraic thinking. It involves learning about variables, expressions, and simple equations. Students also explore patterns, ratios, proportions, and basic geometric principles. Pre-Algebra emphasizes understanding how to manipulate numbers and variables to solve problems and begin working with unknowns, setting the stage for more advanced algebraic concepts. Together, arithmetic and pre-algebra help students develop mathematical fluency, logical reasoning, and problem-solving skills that are crucial for future success in mathematics and real-world applications.

Algebra _ Relation between roots and coefficients Solution: Let α and β be the roots of the given equation. Sometimes the relation between roots of a quadratic equation is given and we are asked to find the condition i.e., relation between the coefficients a, b and c of quadratic equation. This is easily done using the formula α + β = -ba and αβ = ca.
