我们考虑的问题，估计的形状和辐射的对象从校准的一组视图的假设下，对象的反射率是非朗伯的。与传统立体不同，我们不通过比较图像来解决对应问题。相反，我们利用空间中的表面的辐射张量场的秩约束，并使用它来定义每个图像和底层模型之间的差异度量。我们的方法会自动返回场景的辐射估计，沿着其形状，由一个密集的表面表示。前者可用于生成捕捉场景的非朗伯外观的新颖视图。
We consider the problem of estimating the shape and radiance of an object from a calibrated set of views under the assumption that the reflectance of the object is non-Lambertian. Unlike traditional stereo, we do not solve the correspondence problem by comparing image-to-image. Instead, we exploit a rank constraint on the radiance tensor field of the surface in space, and use it to define a discrepancy measure between each image and the underlying model. Our approach automatically returns an estimate of the radiance of the scene, along with its shape, represented by a dense surface. The former can be used to generate novel views that capture the non-Lambertian appearance of the scene.
