Pose estimation using linear or nonlinear composite correlation filters and a neural network

Cameras provide only bi-dimensional views of three-dimensional objects. These views are projections that change depending on the spatial orientation or pose of the object. In this paper we propose a technique to estimate the pose of a 3D object knowing only a 2D picture of it. The proposed technique explores both the linear and the nonlinear composite correlation filters in a combination with a neural network. We present results in estimating two orientations: in-plane and out-of-plane rotations within an 8 degree square range.
