    Abstract: A deep learning network can perform three-dimensional (3D) image reconstruction of a scene from multi-view calibrated two-dimensional (2D) images. The network can include a convolutional neural network that performs feature extraction to generate feature pyramids corresponding to features at different levels of resolution. The feature pyramids can be used to compute a respective cost volume for each feature pyramid at each level of resolution, with the cost volume incorporating a learnable parameter that corresponds to a weight allocated to the “reference” feature pyramid relative to other feature pyramids. A depth map for each input image can be generated based at least in part on the cost volume.

  • Publication number: 20250021015
    Abstract: An etch bias direction is determined based on a curvature of a contour in a substrate pattern. The etch bias direction is configured to be used to enhance an accuracy of a semiconductor patterning process relative to prior patterning processes. In some embodiments, a representation of the substrate pattern is received, which includes the contour in the substrate pattern. The curvature of the contour of the substrate pattern is determined, and an etch bias direction is determined based on the curvature by considering curvatures of adjacent contour portions.
