Full Record; Other Related Related Webb17 jan. 2005 · We use a simulated wavefront to compare the two reconstruction methods. The slope of all subapertures is calculated by integrating the gradient of the wavefront function over one microlens (in our case 64 × 64 pixels). The slope values are saved and used for all reconstruction calculations.

Webb3D shape reconstruction typically requires identifying object features or textures in multiple images of a subject. This approach is not viable when the subject is semi-transparent and moving in and out of focus. Here we overcome these challenges by rendering a candidate shape with adaptive blurring and transparency for comparison with the images. We use … Webb25 okt. 2024 · There are two major approaches to shape reconstruction from slope data. Zonal reconstruction methods use relationships between the heights and slopes of the adjacent positions of the subaperture and estimate the shape with a least-squares method.
