Can viewer proximity be a behavioural marker for Autism Spectrum Disorder?

no code implementations7 Nov 2021 Rahul Bishain, Bhismadev Chakrabarti, Jayashree Dasgupta, Indu Dubey, Sharat Chandran

Screening for any of the Autism Spectrum Disorders is a complicated process often involving a hybrid of behavioural observations and questionnaire based tests.

Low radiation tomographic reconstruction with and without template information

no code implementations23 Dec 2019 Preeti Gopal, Sharat Chandran, Imants Svalbe, Ajit Rajwade

Our results on 3D data show that prior information can be used to compensate for the low-dose artefacts, and we demonstrate that it is possible to simultaneously prevent the prior from adversely biasing the reconstructions of new changes in the test object, via a method called ``re-irradiation''.

Tomographic reconstruction to detect evolving structures

no code implementations11 Sep 2019 Preeti Gopal, Sharat Chandran, Imants Svalbe, Ajit Rajwade

While this is easily feasible when measurements are acquired from a large number of projection views, it is challenging when the number of views is limited.

Learning from past scans: Tomographic reconstruction to detect new structures

no code implementations23 Dec 2018 Preeti Gopal, Sharat Chandran, Imants Svalbe, Ajit Rajwade

The need for tomographic reconstruction from sparse measurements arises when the measurement process is potentially harmful, needs to be rapid, or is uneconomical.

A Large Dataset for Improving Patch Matching

1 code implementation4 Jan 2018 Rahul Mitra, Nehal Doiphode, Utkarsh Gautam, Sanath Narayan, Shuaib Ahmed, Sharat Chandran, Arjun Jain

Similarly on the Strecha dataset, we see an improvement of 3-5% for the matching task in non-planar scenes.

Patch Matching Retrieval

Tomographic Reconstruction using Global Statistical Prior

no code implementations6 Dec 2017 Preeti Gopal, Ritwick Chaudhry, Sharat Chandran, Imants Svalbe, Ajit Rajwade

Recent research in tomographic reconstruction is motivated by the need to efficiently recover detailed anatomy from limited measurements.

Anatomy Compressive Sensing

Improved Descriptors for Patch Matching and Reconstruction

no code implementations24 Jan 2017 Rahul Mitra, Jiakai Zhang, Sanath Narayan, Shuaib Ahmed, Sharat Chandran, Arjun Jain

Scenes from the Oxford ACRD, MVS and Synthetic datasets are used for evaluating the patch matching performance of the learnt descriptors while the Strecha dataset is used to evaluate the 3D reconstruction task.
