The recent developments in the field of computational imaging and data compression have been marked by significant advancements in efficiency, accuracy, and theoretical understanding. A notable trend is the optimization of data representation and compression techniques to handle the increasing demands of high-quality rendering and storage efficiency. Innovations include the development of novel compression algorithms that leverage spatial correlations and entropy modeling to enhance rate-distortion performance, the introduction of randomized compression techniques for flat rank-structured matrices that significantly reduce computational costs without sacrificing accuracy, and the theoretical characterization of binary masks in snapshot compressive imaging systems to optimize hardware parameters. Additionally, there has been progress in the compression of unstructured scientific data through a multi-component, error-bounded framework that outperforms existing methods by leveraging spatial coherence and interpolation techniques.
