Experimental Evaluation and Analysis of LED Illumination Source for Endoscopy Imaging

Prince Mohammad Bin Fahd Universit, Hiren Mewada, Amit R. Patel, Jitendra Chaudhari, Keyur Mahant, Alpesh Vala

The minimally invasive surgery uses a small instrument with camera and light to fit the tiny cut in the skin. The selection of the light depends on the power and driving current of the circuit. It can also help in the standardization of the camera and capture the tissues' true-co…

Inverted-L Shaped Wideband MIMO Antenna for Millimeter-Wave 5G Applications

Amit Patel, Alpesh Vala, Arpan Desai, Issa Elfergani, Hiren Mewada, Keyur Mahant, et al.

Interconnected three-element and four-element wideband MIMO antennas have been proposed for millimeter-wave 5G applications by performing numerical computations and carrying out experimental measurements. The antenna structure is realized using Rogers 5880 substrate (εr = 2.2, ta…

COMPUTATIONLESS PALM-PRINT VERIFICATION USING WAVELET ORIENTED ZERO-CROSSING SIGNATURE

Jitendra Chaudhari, Hiren Mewada, Amit Patel, Keyur Mahant, Alpesh Vala

Palmprints can be characterized by their texture and the patterns of that texture dominate in a vertical direction. Therefore, the energy of the coefficients in the transform domain is more concentrated in the vertical sideband. Using this idea, this paper proposes the characteri…

Multi-Channel Local Binary Pattern Guided Convolutional Neural Network for Breast Cancer Classification

Hiren Mewada, Jawad F. Al‐Asad, Amit Patel, Jitendra Chaudhari, Keyur Mahant, Alpesh Vala

Background: The advancement in convolutional neural network (CNN) has reduced the burden of experts using the computer-aided diagnosis of human breast cancer. However, most CNN networks use spatial features only. The inherent texture structure present in histopathological images…

UWB CPW fed 4-port connected ground MIMO antenna for sub-millimeter-wave 5G applications

Amit Patel, Arpan Desai, Issa Elfergani, Alpesh Vala, Hiren Mewada, Keyur Mahant, et al.

This paper embodies the design and development of a compact Coplanar Waveguide (CPW) fed connected ground Multiple- Input-Multiple-Output (MIMO) antennas operating in the sub-millimeter-wave 5G New Radio (NR) n257/n258/n261 bands. The planar geometry leads to a small and compact…

A fast region-based active contour for non-rigid object tracking and its shape retrieval

Hiren Mewada, Jawad F. Al‐Asad, Amit Patel, Jitendra Chaudhari, Keyur Mahant, Alpesh Vala

Conventional tracking approaches track objects using a rectangle bounding box. Gait, gesture and many medical analyses require non-rigid shape extraction. A non-rigid object tracking is more difficult because it needs more accurate object shape and background separation in contra…
