Gigapixel imaging refers to the process of capturing, storing, and displaying images with a resolution of one billion pixels or more. This technology allows for extremely high-resolution images to be created, providing detailed views of complex and large-scale scenes. Gigapixel imaging is commonly used in fields such as astronomy, digital pathology, and cultural heritage preservation. Researchers in this area focus on developing advanced imaging techniques, algorithms, and hardware to enable the capture and analysis of gigapixel images. This research has the potential to revolutionize industries such as healthcare, surveillance, and virtual tourism.
