This m file hide an image jpeg,png in another jpeg,png image. The height and width of the secret image is in LSB of 1st 32 pixels of 1st row of the cover image.This helps in the recovery of secret image. The secret image must be smaller than cover image.A message box will appear with a number ,that number is the maximum product of width and height of secret image that can be successfully embedded in the cover image. The final png image will appear in workspace with random name.This image contains the secret image.One such png image is in the zip file with name 4447.png it contains an image of res 100x122.

Exploring C++ uses a series of self–directed lessons to divide C++ into bite–sized chunks that you can digest as rapidly as you can swallow them. The book assumes only a basic understanding of fundamental programming concepts (variables, functions, expressions, statements) and requires no prior knowledge of C or any other particular language. It reduces the usually considerable complexity of C++. The included lessons allow you to learn by doing, as a participant of an interactive education session. You’ll master each step in a one sitting before you proceed to the next. Author Ray Lischner has designed questions to promote learning new material. And by responding to questions throughout the text, youll be engaged every step of the way.

This article discusses some issues that a typical Windows C++ programmer will encounter when approaching Symbian OS for the first time. Our experience in developing for three successive versions of Symbian OS has given us considerable perspective on what can be difficult when working in this otherwise rich and stable environment. While one reason for Symbian s success may be the desire of many mobile phone manufacturers not to be tied to Microsoft, the other reason is that Symbian has put together a lightweight, elegant system that succeeds in providing a very impressive range of functionality. Here are some pointers to help ease the transition to successful Symbian OS application development.

A Public Key Infrastructure (PKI) binds cryptographic public keys to physical entities through digital certificates. A PKI includes components that issue digital certificates and distribute certificate status information. PKI users select one or more certificate issuers as trust anchors, and establish security services based on certificates that may be validated using one of their trust anchors.

This C++ code example demonstrates how to localise an application to adapt to the selected phone language. The example application has two sets of localised strings (English and German) for the application name, labels, text, and image. The application also includes number, currency, date, and time localisation, in which the TLocale method is used for localisation even if the selected phone language is neither one of the two application languages. The updated example has been tested to support S60 5th Edition and touch UI.

Abtract - We propose a new family of fi lter banks, named NDFB, that can achieve the directional decomposition of arbitrary N-dimensional (N ≥ 2) signals with a simple and effi cient tree-structured construction.

Abstract - A fl exible multiscale and directional representation for images is proposed. The scheme combines directional fi lter banks with the Laplacian pyramid to provides a sparse representation for two- dimensional piecewise smooth signals resembling images. The underlying expansion is a frame and can be designed to be a tight frame. Pyramidal directional fi lter banks provide an effective method to implement the digital curvelet transform. The regularity issue of the iterated fi lters in the directional fi lter bank is examined.

For developers who design and program devices that use the USB interface. Introduce the USB and help to get your devices and communicating as quickly and easily as possible.The USB is versatile enough for a wide range of peripheral devices. Standard peripherals that use USB include mice, keyboards, drives, printers, and audio/video devices. USB is also suitable for data-acquisition units, control systems, and other devices with specialized functions, including one-of-a-kind designs.

this is a document about radio frequency identification RFID, this was a project ,i have done last year ,actually this technology is a very inpotrtant one due to its relation with newest technologies , like GPS , or the miniturization of integrated circuits ,and that is described in chapter 3 . chapter 1 gives an introduction of the technology RFID , chapter 2 gives a discussion of a library using RFID , and chapter 3 is about the future of RFID , and finally the conclusion .
