The Analysis of Satellite Images for Anomaly Identification in Patterns

Anomaly detection in remotely sensed imagery constitutes a pivotal endeavor with a multitude of applications, encompassing areas such as environmental surveillance and precision agriculture. A variety of methodologies have been formulated to augment the identification of anomalies, defined as deviations from anticipated patterns within image datasets. These approaches capitalize on sophisticated computational strategies and advanced machine learning algorithms to enhance both accuracy and operational efficiency. Anomaly detection in remotely sensed imagery can be implemented through an array of techniques, including heterogeneous and Edge Computing (EC), CNN, feature spaces with multi-dimensionality, unified anomaly detection frameworks, and unsupervised learning for the identification of burnt areas, among others. This manuscript elucidates various methodologies and state-of-the-art technologies pertinent to anomaly detection. Although each of these methodologies exhibits significant advancements, obstacles and constraints continue to exist pertaining to the requirements for digital assets and the imperative for real-time processing functionalities. Subsequent study endeavors may prioritize the refinement of these models to enable more extensive applications and to improve their flexibility in accommodating emerging data sources.
