We use cookies to help provide and enhance our service and tailor content and ads. We cast the reconstruction task as an optimization problem where a random 3D image is iteratively refined to match its microstructural features to those of the exemplar. Price: $2.5 per high-quality STL file. As such, I used docker on my Mac to reconstruct the 3D points. Some features of the site may not work correctly. A single image is only a projection of 3D object into a 2D plane, so some data from the higher dimension space must be lost in the lower dimension representation. From the displacement of the selected image points the algorithm estimates a depth surface for the scene. By augmenting the architecture of VGG19 with a permutation operator, we enable it to take 3D images as inputs and generate a collection of 2D features that approximate an underlying 3D feature map. https://doi.org/10.1016/j.cad.2020.102906.
