This paper presents an experimental analysis of information loss in degraded environments for traditional 2D imaging and 3D integral imaging. We consider mutual information to quantify this information loss. Our experimental analysis shows that 3D in

In this paper, we address the problem of object recognition in degraded environments including fog and partial occlusion. Both long wave infrared (LWIR) imaging systems and LiDAR (time of flight) imaging systems using Azure Kinect, which combine conv

Traditionally, long wave infrared imaging has been used in photon starved conditions for object detection and classification. We investigate passive three-dimensional (3D) integral imaging (InIm) in visible spectrum for object classification using de

We overview the previously published work for object detection in low light and occlusion using deep learning and polarimetric 3D integral imaging. 3D polarimetric integral imaging outperformed in object detection and classification in degraded envir

Polarimetric imaging can become challenging in degraded environments such as low light illumination conditions or in partial occlusions. In this paper, we propose the denoising convolutional neural network (DnCNN) model with three-dimensional (3D) in

In quantitative phase imaging, generally, a highly coherent light source such as a laser is used to achieve the interference easily. But due to laser’s high spatio-temporal coherence, speckles and spurious fringes are formed, which degrades the ima

Polarimetric imaging is useful for object recognition and material classification because of its ability to discriminate objects based on polarimetric signatures of materials. Polarimetric imaging of an object captures important physical properties s

We overview polarimetric sensing of objects in low light illumination conditions using three dimensional integral imaging in the visible and long wave infrared (LWIR) domains. SNR of polarimetric imaging in both domains is compared.
