Applications: 1. The present invention provides a method and system for generating High Dynamic Range (HDR) images for use in at least one electronic device. 2. The method comprising: capturing, a plurality of frames of at least one image, wherein the respective frames are captured at different gain, blending, said plurality of frames captured at different gain, by signing intensity - based weights to catch pixel of respective frame, and thereby fusing said frames with intensity - based weights, for obtaining blended image with maximum information related to said HDR image.
Advantages: 1. The present system requires a camera with manual access to gain control and no additional hardware is required. This is the major advantage of the present invention as it can be implemented using the off - the - shelf capturing devices with no additional hardware requirement. This makes it convenient to integrate the feature of high illumination HDR photography with the current hardware available in the market. This further reduces the cost and complexity of the system to generate HDR image. 2. In the present system, additional hardware requirement is completely eliminated which makes the integration of the described feature with the cameras much more convenient and simple. 3. The present system protects the image from losing data due to saturation. The present invention retrieves lost information from the LDR images taken at a series of different gains. The resultant HDR image is a blended image with maximum information of the captured scene. 4. The present system also eliminates the drawback of obtaining better quality image while handling excessively illuminated environment. 5. The parallelizable pixel based blending algorithm is non-trivial. None of the existing HDR blending algorithm is parallelizable and thus it improves the computation time a lot. 6. The capturing technique using the gain controller is essential as handling altering gain controller is difficult as the controller is generally non accessible for end users in the imaging devices.

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.
