Differential imaging is a research area in the field of image processing and computer vision that focuses on detecting and highlighting differences between images. This technique is often used in medical imaging, surveillance, and remote sensing applications to enhance specific features or anomalies in images that may not be easily visible to the naked eye. Differential imaging algorithms analyze pairs of images to identify changes in brightness, color, texture, or other visual properties, helping to identify important details or isolate specific objects or regions of interest. By comparing images before and after a particular event or condition, researchers can track changes over time and gain valuable insights into dynamic processes or subtle differences in the environment.
