Chaudhuri's work have been mainly in the areas of pattern recognition, image processing, and computer vision.
He is known to have developed a number of techniques including a methodology for acquiring super-resolved depth map from defocus and is one of the pioneers of researches in motion-free super-resolution.
His work covered the fields of motion estimation, restoration, computational photography and biomedical image analysis which has applications in cytology, microscopy, material science, biomedical science and pharmaceutics.
Computational haptics is another area of his researches.
He has developed several new methodologies and holds US and Indian patents for a number of them.
He has documented his researches by way of several articles; Google Scholar and ResearchGate, online article repositories of scientific articles, have listed many of them.
Besides, he has co-authored six books viz.
Motion-Free Super-Resolution, Hyperspectral Image Fusion,Blind Image Deconvolution: Methods and Convergence, Depth From Defocus: A Real Aperture Imaging Approach, Video Analysis and Repackaging for Distance Education and Ambulation Analysis in Wearable ECG and edited two more, Perspectives and Policies on ICT in Society: An IFIP TC9 (Computers and Society) Handbook and Super-Resolution Imaging.

Chaudhuri sat in the editorial boards of several journals including International Journal of Computer Vision of Springer, IEEE Transactions on Pattern Analysis and Machine Intelligence of Institute of Electrical and Electronics Engineers and IET Computer Vision of Institution of Engineering and Technology.
He chaired a program at the  2005 edition of International Conference on Computer Vision (ICCV) at Beijing and served as the program chair of Indian Conference on Computer Vision, Graphics and Image Processing (ICVGIP) held in 2006 at Mumbai; he also co-chaired the 2002 edition of ICVGIP.
He has delivered invited or plenary speeches in several conferences including the Fifth National Conference on Computer Vision, Pattern Recognition, Image Processing and Graphics (NCVPRIPG) held in December 2015 at Patna and has been involved in external teaching programs of IIT Bombay and other institutions.
He serves as a member of the Council of the Indian National Science Academy, the Publications Committee of International Conference on Robotics and Automation for Humanitarian Applications (RAHA 2016) and the Advisory Council of the Information Technology Research Academy.
As the Dean of International Relations of IIT Bombay, he has been involved in inter-institutional cooperations; spearheading the IITB's efforts to open an off-campus in New York and the establishment of cooperation with International Cooperation Between the Advanced Institute of Manufacturing With High-Tech Innovations (AIM-HI), Taiwan count among them.
