Steganography is the art and science of hiding that a communication is taken place. It embeds the secret file (text, audio or image) in other carrier file. Text in image steganography is considered in this work. The proposed stegosystem uses Spread Spectrum technique which is applied in spatial domain together with error correction coding. These are used to increase the security and robustness of...
Texture analysis continues to evolve as a feature measurement technique to analyze and classify image data. Texture features could be derived using various approaches. One of the most important problems in the field of pattern analysis and texture classification is the problem of finding an appropriate set of features-vector that represent observations with reduced dimensionality without sacrificing...
Rout planning system is one of the interesting problems for a car navigation system. There could be many possible routes for a driver when a set of origin-destination pair is given. This paper addresses the problem of selecting route to a given start and destination on an actual map under user defined environment (static environment). The proposed solution using genetic algorithm (GA) with variable...
Steganography deals with hiding of messages such that potential monitors do not even know that a message is being sent. All files sent through Internet may be affected, either by compression due to the compression nodes or by transmission errors during the transmission or by noise. The proposed system provides certain level of immunity against moderate compression ratios and operates successfully...
