Identification of radiation induced dark current sources in pinned photodiode CMOS image sensors [PDF]

, 2011
This paper presents an investigation of Total Ionizing Dose induced dark current sources in Pinned PhotoDiodes (PPD) CMOS Image Sensors based on pixel design variations. The influence of several layout parameters is studied. Only one parameter is changed

HYPERSPECTRAL IMAGE ANALYSIS USING A CUSTOM SPECTRAL CONVOLUTIONAL NEURAL NETWORK [PDF]

International Journal of Intelligent Computing and Information Sciences, 2022
In recent time, the most applied classification method for hyperspectral images is based on the supervised deep learning approach. The hyperspectral images require special handling while it consists of hundreds of bands / channels.

Robust Image Encryption based on Balanced Cellular Automaton and Pixel Separation [PDF]

Radioengineering, 2016
The purpose of image encryption is to protect content from unauthorized access. Image encryption is usually done by pixel scrambling and confusion, so process is possible to reverse only by knowing secret information.

Local binary pattern‐based reversible data hiding

CAAI Transactions on Intelligence Technology, 2022
A novel local binary pattern‐based reversible data hiding (LBP‐RDH) technique has been suggested to maintain a fair symmetry between the perceptual transparency and hiding capacity. During embedding, the image is divided into various 3×3 blocks.
