Geometric Solution of Image Degradation by Diffraction in Lensless Sensing and Microscopy
Sanjeev Kumar, Manjunatha Mahadevappa, Pranab Kumar Dutta
This paper proposes a non-computational method of counteracting the effect of image degradation introduced by the diffraction phenomenon in lensless microscopy. All the optical ima…
A semi-analytic reconstruction method for Diffuse Optical Tomography
Tapan Das, P. K. Dutta
The Diffuse Optical Tomography (DOT) has received considerable attention in the recent years in the field of biomedical imaging and disease detection. However, imaging through high…
Lensless in-line holographic microscopy with light source of low spatio-temporal coherence
Sanjeev Kumar, Manjunatha Mahadevappa, Pranab Kumar Dutta
Lensless microscopy with coherent or partially coherent light sources is a well known imaging technique, commonly referred as digital in-line holographic microscopy. In the establi…
EM based Framework for Single-shot Compressive Holography
Sanjeev Kumar, Manjunatha Mahadevappa, Pranab Kumar Dutta
Lensless in-line holography is a simple, portable, and cost-effective method of imaging especially for the biomedical microscopy applications. We propose a multiplicative gradient…
Photonic crystal fiber for high resolution lensless in-line holographic microscopy
Sanjeev Kumar, Manjunatha Mahadevappa, Pranab K. Dutta
We propose to use high numerical aperture single mode optical fibers like photonic crystal fiber for lensless in-line holographic microscopy. Highly divergent beam helps to overcom…
Faster method for Deep Belief Network based Object classification using DWT
Saurabh Sihag, Pranab Kumar Dutta
A Deep Belief Network (DBN) requires large, multiple hidden layers with high number of hidden units to learn good features from the raw pixels of large images. This implies more tr…
