Abstract: Methods and devices for inpainting a three-dimensional scene in response to object removal. A 3D scene is stored in the form of Gaussian splats. When object removal occurs, a never-before-seen (NBS) area may be revealed that requires inpainting as a result of pruning of the Gaussian splats. Object masks are dilated and remapped to the pruned scene to identify pixels bordering the NBS area. A reference image is inpainted and the geography of its NBS area reconstructed using depth prediction and smoothing. The reference image is then warped to other viewpoints and the warped images and their inpainting masks are input to a multi-view restoration model created by modifying a pre-trained diffusion-based inpainting model to use sparse space-time attention layers to ensure consistency among views. Those refined views are then used to refine the pruned 3D Gaussian model.

Abstract: Provided are systems and methods related to hybrid reflective microscope objectives and lens systems used in a spectroscopy system. The objective lens system includes a primary aspheric mirror having a first R-value; and a secondary aspheric mirror having a second R-value smaller than the first R-value, where in the objective lens system has a working distance of at least 20 mm and a numerical aperture of 0.29-0.65, and wherein surfaces of the primary and secondary aspheric mirrors have a non-zero sixth order aspheric parameter.

Abstract: A microscope for examining a specimen configured to receive a first light source or a second light source. The first light source being configured to emit a first output light through a first pupil, and the second light source being configured to emit a second output light through a second pupil that is different than the first pupil. The microscope comprises a frame, a source objective, and first and second optical assemblies. The first and second optical assemblies are removably connectable to the frame. The first optical assembly comprises a first set of optical elements that are configured to pass the first output light to an imaging pupil of the source objective, and the second optical assembly comprises a second set of optical elements configured to pass the second output light to the imaging pupil.
