In previous chapters, we have explored advanced plenoptic imaging and reconstruction techniques, enabling images and videos to reach gigapixel-level resolution. This breakthrough unlocks new possibilities for a wide range of applications and industries. However, traditional computer vision methods, tailored for megapixel-level data, are ill-equipped to handle the complexities of gigapixel-level data, which often feature large-scale scenes with hundreds of objects and intricate interactions. As a result, these methods face significant limitations in both precision and efficiency.
