Abstract

A computer-implemented method for performing compressive sensing of light transport matrix includes receiving a 3D dataset comprising image volume data and randomly selecting a plurality of points on a space curve traversing the 3D dataset. A light transport matrix comprising a plurality of light transmittance values is calculated. Each light transmittance value corresponds to light transmittance between a pair of points included in the plurality of points. An optimization problem is solved to determine a plurality of sparse coefficients which reproduce the light transport matrix when the sparse coefficients are multiplied by a predetermined dictionary of basis vectors. Once determined, the sparse coefficients are stored on a computer-readable medium.
