Exploiting Inter-pixel Coherence II
Let’s come back to the discussion on compressive sensing applied to light transport problem. We will talk about two approaches to exploit inter-pixel coherence today. The first is described to in the paper Compressive Light Transport Sensing by Peers et … Continue reading

Exploiting Inter-pixel Coherence
Recall the measurement equation from last time: Suppose again that the responses of the pixels to each light source are coherent. That is, we may hope that there is a basis such that the columns of are sparse. Then, we … Continue reading

Compressive Sensing and Precomputed Radiance Transfer?
Following the development in Peers et. al.’s Compressive Light Transport Sensing (download), the light transport problem can be described by the following matrix equation:
