Abstract

We propose the application of light field cameras and depth-selective 4-D IIR filtering to enable video surveillance, leveraging the post-capture depth-selective filtering enabled by computational photography. Novel ultralow-complexity differential-form depth-selective 4-D IIR filter algorithms and their corresponding architectures are proposed for processing 4-D light fields. Practical results are presented for real-world video sequences, and a CMOS VLSI implementation of the arithmetic processing elements is synthesized. The architecture shows \(86.66\), \(78.94\,\%\) reduction in multipliers and adders compared to direct-form structure and delivers 26 frames/s for light fields of size \(16\times 16\times 128\times 128\).
