MODULAR BUNDLE ADJUSTMENT FOR PHOTOGRAMMETRIC COMPUTATIONS
Bundle adjustment Camera model Analytical Jacobians Software Photogrammetry Tilt-shift lens
2018/6/4
In this paper we investigate how the residuals in bundle adjustment can be split into a composition of simple functions. According to the chain rule, the Jacobian (linearisation) of the residual can b...
Rice U. scientists slash computations for ‘deep learning’
Rice U. scientists slash computations deep learning
2017/7/21
Rice University computer scientists have adapted a widely used technique for rapid data lookup to slash the amount of computation — and thus energy and time — required for deep learning, a computation...
Targeted malleability: homomorphic encryption for restricted computations
restricted computations homomorphic encryption
2015/8/5
We put forward the notion of targeted malleability: given a homomorphic encryption scheme, in various scenarios we would like to restrict the homomorphic computations one can perform on encrypted data...
