Digital image processing or signal processing have been widely utilized for defence, security and healthcare applications, including the detection and tracking of minuscule targets, missile guidance, vehicle navigation, broad area surveillance, healthcare applications using Deep and Machine Learning techniques and automatic/assisted target recognition will also introduced in the form of chapters in this edited book. In military and security applications, one objective of an image processing strategy is to minimize the burden of human analysts in order to accommodate the ever-increasing volume of picture data acquired. A second, more difficult objective for researchers in image processing is to create algorithms and methods that greatly facilitate the development of completely autonomous systems capable of making judgments and taking actions based on all sensor inputs.
The purpose of this special issue is to bring together researchers that create or develop sophisticated image processing techniques/systems, with a focus on defence, security and healthcare applications.
