I am currently looking out for a motivated and enthusiastic PhD student, interested broadly in the areas of "low level image processing", which basically includes
problems such as image filtering, tomographic reconstruction, source separation, restoration, compression and compressive sensing. Many of these tasks are used in various important steps to pre-process image data to be input for higher level tasks such as recognition or classification. The ideal candidate should have some background/interest in signal processing and statistical/machine learning
methods which are widely applicable in solving the aforementioned problems. If interested, please take a look at our research page below, and email/meet me for any questions. You will be required to apply to the PhD programme of the
CSE department at IITB and go through the procedure (including entrance test) outlined.
Note to students seeking internships: I do not have any open positions for summer/winter research internships at this point of time.
I receive an overwhelming number of requests
for internships or summer projects, and I am simply unable to answer them.
