“…The method combines explicit point cloud and implicit neural representations to enable highquality mesh and surface reconstruction for object deformation and lighting estimation. With the trained SPIDR model, various geometric edits can be applied to the point cloud representation, which can be used for image editing.Zhang et al introduced a new method for rendering point clouds with frequency modulation, which enables easy editing of shape and appearance [155]. The method converts point clouds into a set of frequency-modulated signals that can be rendered efficiently using Fourier analysis.…”

Super-resolution optical imaging is crucial to the study of cellular processes. Current super-resolution fluorescence microscopy is restricted by the need of special fluorophores or sophisticated optical systems, or long acquisition and computational times. In this work, we present a deep-learning-based super-resolution technique of confocal microscopy. We devise a two-channel attention network (TCAN), which takes advantage of both spatial representations and frequency contents to learn a more precise mapping from low-resolution images to high-resolution ones. This scheme is robust against changes in the pixel size and the imaging setup, enabling the optimal model to generalize to different fluorescence microscopy modalities unseen in the training set. Our algorithm is validated on diverse biological structures and dual-color confocal images of actin-microtubules, improving the resolution from ~ 230 nm to ~ 110 nm. Last but not least, we demonstrate live-cell super-resolution imaging by revealing the detailed structures and dynamic instability of microtubules.
