    Abstract:

Applications: The Fr AD algorithm is a generalization of classical anisotropic diffusion. Also, it is a pseudo PDE based algorithm between the Perona Malik model and fourth order anisotropic diffusion equations. The computations of the fractional derivatives are carried out in the spatial domain instead of the existing Fourier domain-based methods. Additionally, very few parameters are selected manually in the proposed algorithm. These manually tuned parameters do not depend on the image under restoration and remain fixed. The iterative algorithm takes the initial airlight map as the input, and then subsequent iterations derive towards the refined airlight map. This algorithm does not only applicable to gray and RGB images, but can work on multispectral images. The proposed solution can be implemented on hardware and useful for improving the poor visibility due to fog and haze. Therefore, it is useful in transport, surveillance and security applications.
Advantages: Can be Implemented with low cost processors with near real time processes.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
