Compressively sampled light field reconstruction using orthogonal frequency selection and refinement

作者：

Highlights：

• Light field acquisition devices suffer from a spatio-angular trade-off.

• Compressive reconstruction is possible from a small number of spatial samples.

• The 4D Fourier spectrum of a light field is sparse.

• Sparsity of the light field is better preserved in the continuous Fourier domain.
