Computational imaging is a field of study that combines methods from computer science, mathematics, and imaging science to develop new imaging techniques that go beyond traditional optical systems. These techniques can enhance the capabilities of imaging systems, improve image quality, and enable new imaging applications. Computational imaging involves the processing and analysis of images using computational algorithms to reconstruct, enhance, or manipulate images in various ways. It has applications in areas such as medical imaging, remote sensing, security imaging, and microscopy.
