Please give more details of new technical application area:
We developed an algorithm in which optical flow is used here for motion estimation which gives horizontal and vertical velocity components. We utilize the optical flow to localize the high alert regions. To have a better localization and motion signatures, we develop a fractional order technique to compute optical flow. Also, the localization is characterized by brightness of image, magnitude, directions, vorticity and irrotational components of the optical flow. Visual features show different patterns for extreme and normal weather situations. A study on interpolation and extrapolation of the image sequence is also presented. Optical flow based interpolation and Advection-anisotropic-diffusion based extrapolation model give promising results on the satellite imagery data suggested by the funding agency ISRO. We observe that images captured by satellite INSAT 3D were acquired at large amount of time interval. For better accuracy of weather prediction and analysing the pattern of cloud motion, it is necessary to acquire image in between the given time frame. Interpolation of satellite images in space and time was carried out by a particle tracking technique. Application of this technique was to estimate a continuous distribution of a satellite derived water property in Lake Superior chlorophyll measurements. Optical-flow-based temporal interpolation was employed. The proposed technique can be embedded with the current weather forecasting system. The stand alone software is handed over to ISRO, and a team of SAC Ahmedabad is working to deploy this technique in their system.

I-Mitra(आई-मित्र) Welcomes You..
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.
