Equivalent Latitude Computation Using Regions of Interest (ROI)

Equivalent Latitude Computation Using Regions of Interest (ROI)

This paper introduces a novel algorithm to compute equivalent latitude by applying regions of interest (ROI). The technique is illustrated using code written in Interactive Data Language (IDL). The ROI method is compared with the "piecewise-constant" method, the approach commonly used in atmospheric sciences, using global fields of atmospheric potential vorticity. The ROI method is considerably...

On Registration of Regions of Interest (ROI) in Video Sequences

This paper addresses the problem of registering regions of interest in two video sequences. Potential applications include blob fusion and target tracking in blurry sequences. It is assumed that the moving target is tracked successfully in one of the two sequences and is represented by a bounding box in each frame of the first sequence. The goal is to find the corresponding bounding box for eac...

Intelligent Multi-Level Regions-of-Interest (ROI) Document Image Encryption Using an Online Learning Model

Image-based document management systems have become increasingly popular for handling documents that contain both text and graphical elements. When such systems are used to store confidential information, document security is a key concern. Conventional encryption techniques used for images fail to provide the level of flexibility required by such document management systems. Newer image encryp...

Backwards Compatible, Multi-Level Regions-of-Interest (ROI) Image Encryption Architecture with Biometric Authentication

Digital image archival and distribution systems are an indispensable part of the modern digital age. Organizations perceive a need for increased information security. However, conventional image encryption methods are not versatile enough to meet more advanced image security demands. We propose a universal multi-level ROI image encryption architecture that is based on biometric data. The propos...
