Unlike earlier models, Evi has been developed from the outset for application to passenger ships in a sea environment, targeting the largest cruise liners and ROPAX. Utilising an advanced evacuation simulation tool, code-named Evi (Evacuability index), it is the main target of the Passenger Evacuation Group of the SSRC to develop a risk-based framework to(More)
Steganography is an art and technique of hiding data in some media i.e image, audio or video file. For hiding data various steganography techniques are used. This paper is an effort to provide comprehensive comparison of these steganography techniques based on different performance metrics such as PSNR, MSE and Embedding capacity. [16] The embedding(More)
