guaranteed. Thus importance of scanning documents, images, etc has gained lot importance and has also become a standard practice with many. To ensure that these stored documents
words Cryptos meaning cover and grafia meaning writing [1] defining it as covered writing. In image cryptography the information is hidden exclusively in images. Cryptography is the art and science of secret communication .It is the practice of encoding/embedding secret information in a manner such that the existence of the information is invisible. The original files can be referred to as cover text, cover image, or cover audio. After inserting the secret message it is referred to as Crypto-medium. A
FEATURE EXTRACTION APPROACHES: Principal Component Analysis: PCA is a useful statistical technique that has found application in fields such as face recognition and image compression, and is a common technique for finding patterns in data of high dimension. Technically, a principal component can be defined as a linear combination of optimally-weighted observed variables. In order to understand the meaning of this definition
Chapter one 1.1 Introduction Face detection is concerned with finding whether or not a face exists in a given image; it is the first step of any fully automatic system that analyzes the information contained in faces (e.g., identity, gender, expression, age, race, and pose). The current evolution in computer technology in recent years has facilitated the development of real-time computer human interaction. Examples can be found, particularly in biometrics and human computer interaction, as the
CHAPTER -1 INTRODUCTION The outbreak of digital image processing in 1920’s has revolutionalised the communication process [l]. The images were the first language used by the humans for interaction. The images in the form of pictures were carved on stone which became the first language for communication and these carvings were available for the future generation. With the technical advancements in recent times; image processing techniques has became an important part of the communication system. From
detecting the traffic sign from the input image or video stream then, classifying the detected sign and recognition of it. The system is to detect traffic signs correctly so that drivers can be alerted and react properly to the encountered traffic situations. We have used feature based method for traffic sign detection. In this method the image of the traffic sign was cropped and matched with the original image, identifying the key points
SECTION II Explain Foucault`s biopower and how it functions in Kubrick`s 2001: A Space Odyssey. The movie, 2001: A Space Odyssey starts with an image of a totally free, pre-human ape community and continues in an ultra modern world with its extremely disciplined and conditioned subjects. Biopower in the Foucauldian sense is perfectly illustrated by the sharp difference in the usage of violence in the two scenarios. The ape was violently beaten to death by a wood stick in ancient times whereas the
CHAPTER-2 LITERATURE REVIEW 2.1) Chronic wound and quality of life Wound healing, one of the typical organic process in the human body, accomplished through four unequivocally and exceptionally customized stages known as hemostasis, inflammation, proliferation and remodeling. It is vital that all these four stages must happen in the best possible grouping and time allotment for an injury to heal effectively. Intrusions or prolongation in the process prompts delayed injury healing or a non-healing
