Automatic form-feature recognition using neural-network-based techniques on boundary representations of solid models
TL;DR: An algorithm for recognition using neural-net-based techniques has been developed, and a suitable net architecture, which is similar to the multilayer perceptron in function and which implements the algorithm, has been designed.

Multi-User Nonlinear Optical Cryptosystem Based on Polar Decomposition and Fractional Vortex Speckle Patterns
Harsh Vardhan,Shashikanth Prabhakar,Sakshi,Ravi Kumar,Salla Gangi Reddy,Ravindra Pratap Singh,Kehar Singh +6 more
TL;DR: In this article , the authors proposed a new multiuser nonlinear optical cryptosystem using fractional-order vortex speckle (FOVS) patterns as security keys.

An Asymmetric Optical Cryptosystem Using Physically Unclonable Functions in the Fresnel Domain
Shashikanth Prabhakar,Harsh Vardhan,Ravi Kumar,Salla Gangi Reddy,Sakshi,Ravindra Pratap Singh +5 more
TL;DR: In this paper , the authors proposed a new asymmetric cryptosystem for phase image encryption, using the physically unclonable functions (PUFs) as security keys, where the original amplitude image is first converted into a phase image and modulated with a PUF to obtain a complex image.
Analysing the Grain size and asymmetry of the particle distribution using auto-correlation technique
TL;DR: In this paper , a simple mathematical tool, the auto-correlation function, was used to determine the grain size from the microscopic images, which has been extensively studied for finding the size of random optical patterns.
