MarrNet: 3D Shape Reconstruction via 2.5D Sketches.  #deeplearning #nips #computervision

  • 3D object reconstruction from a single image is a highly under-determined problem, requiring strong prior knowledge of plausible 3D shapes.
  • In this work, we propose an end-to-end trainable framework, sequentially estimating 2.5D sketches and 3D object shapes.
  • First, compared to full 3D shape, the 2.5D sketch is much easier to be recovered from the 2D image, and to transfer from synthetic to real images.
  • Second, for 3D reconstruction from the 2.5D sketches, we can easily transfer the learned model on synthetic data to real images, as rendered 2.5D sketches are invariant to object appearance variations in real images, including lighting, texture, etc.
  • Third, we derive differentiable projective functions from 3D shapes to 2.5D sketches, making the framework end-to-end trainable on real images, requiring no real-image annotations.

Right Now, Artificial Intelligence Is The Only Thing That Matters: Look Around You

  • CEO Sundar Pichai wants to put artificial intelligence everywhere , and Google is marshaling its army of programmers into the task of remaking itself as a machine learning company from top to bottom.
  • If there’s one thing the world’s most valuable companies agree on, it’s that their future success hinges on artificial intelligence.
  • Google is continuing to invest heavily in deep learning at a time its head of machine learning, John Giannandrea , is calling the artificial intelligence spring (as opposed to the AI winter of earlier times).
  • The company’s Founders’ letter this year mentions machine learning up to five times , leaving no doubt that it believes its advantages in this area will give it the edge in the coming years .
