Good Open Source Software Alternatives for Digital Image Processing “A picture is worth a thousand words.” − Anonymous Nowadays, Digital Image Processing has a tremendous number of applications: from daily routine life to biomedical equipments, and from industries to military. Several image processing algorithms are being practiced, which handle different complex tasks with ease in a fraction of time. Digital Image Processing also plays a vital role to provide capabilities to machine, so that they could ‘see’, ‘analyze’ and ‘predict’ the visuals – just like a normal human being. For implementing and testing complex image processing algorithms, the researchers always take help of good image processing tools and software. Several software (e.g. MATLAB) are good in implementation and testing of such algorithms. But, the main drawback is they are licensed, costly and take more size on hard disk. Also, some software effect on the performance of the OS, thus m...
Hardware level Implementations of DES Cryptography Algorithm using Programmable Logic Devices (PLDs) “Encryption works best if it is ubiquitous and automatic. It should be enabled for everything by default, not a feature you only turn on when you’re doing something you consider worth protecting.” − Bruce Schneier, Cryptographer, Privacy and Security Specialist Encryption is a process used to transform a plain data into a form of data, which is non-interpretable to anyone except for those who possess the knowledge of the process. Several encryption techniques are being used to keep secure the digital data in the computers, data centers, while transferring using the Internet, as well as in digital video, voice, or text conversations. Hence, data encryption became a necessity to maintain privacy, protecting anonymity and sometimes for protecting lives [1]. There are several data encryption techniques are being practiced in world, which can be cate...
