Focus Image

Focus image research centers on improving image quality and information extraction by addressing limitations in focus and depth of field. Current efforts concentrate on developing advanced algorithms, such as those incorporating deep learning and differentiable optical models, to achieve tasks like multi-focus image fusion, realistic bokeh rendering, and accurate point spread function estimation. These advancements are crucial for various applications, including microscopy, astronomy, and mobile photography, enabling higher-quality images and more precise data analysis from diverse imaging systems. The development of large, high-quality datasets specifically designed for challenging scenarios, such as nighttime or raindrop-focused images, is also a key area of progress.
