  • Controlled Generation of Self-images of a Microlens Array and the Second Harmonic Talbot Effect 
    HARSHITH, B. S.; Samanta, G.K. (Springer Nature, 2021-03)
    Here, we report on a simple experimental scheme to demonstrate the second harmonic (SH) Talbot effect. Using a dielectric Microlens array (MLA) as an array illuminator at 1064 nm on to a 1.2 mm thick BiBO crystal, we have ...
  • MMBERT: Multimodal BERT Pretraining for Improved Medical VQA 
    Khare, Yash; BAGAL, VIRAJ; Mathew, Minesh; Devi, Adithi; Priyakumar, U Deva; Jawahar, C.V. (IEEE, 2021-05)
    Images in the medical domain are fundamentally different from the general domain images. Consequently, it is infeasible to directly employ general domain Visual Question Answering (VQA) models for the medical domain. ...
  • A Simple Algorithm for Diffuse Optical Tomography (DOT) without Matrix Inversion 
    Paul, Ria; K, Murali; CHETIA, SUMANA; Varma, Hari M. (Optica Publishing Group., 2021-06)
    We present a computationally fast algorithm for estimating the optical property distribution of turbid media using diffuse optics principles without the inversion of Jacobian matrix. The algorithm is validated by simulations ...
