Abstract:
1. A method for spatial reconstruction of a plenoptic image of an object, the method comprising: accessing a plenoptic image captured by a plenoptic imaging system, the plenoptic imaging system performing a plenoptic imaging process that is modeled by a pupil image function (PIF) that relates an object to a plenoptic image formed by that object; and applying a PIF inversion process to the captured plenoptic image to produce an estimate of the object; wherein: the object comprises K object components; the PIF comprises K component PIFs, each component PIF modeling the plenoptic imaging process for the corresponding object component; and the step of applying a PIF inversion process to the captured plenoptic image produces estimates of each object component; the plenoptic imaging process is modeled as a vector-matrix operation [Iv the step of applying a PIF inversion process comprises solving an optimization problem to minimize a metric with respect to the [Iv
