Lippmann Photography: A Signal Processing Perspective
Lippmann photography provides a great opportunity to demonstrate several fundamental concepts in signal processing.
How Asynchronous Events Encode Video
Instead of recording video by capturing frames, event-based cameras have sensors that emit events when their inputs change, thus encoding information in the timing of events.
Asynchrony Increases Efficiency: Time Encoding of Videos and Low-Rank Signals
Event-based sensing can present significant improvements in power efficiency when compared to traditional sampling, because (1) the output is a stream of events where the important information lies in the timing of the events, and (2) the sensor can easily be controlled to output information only when interesting activity occurs at the input.
Encoding and Decoding Mixed Bandlimited Signals using Spiking Integrate-and-Fire Neurons
We propose a setup to sample a set of bandlimited signals, by mixing them and sampling the result using different IF-TEMs.

Sampling and Reconstruction of Bandlimited Signals with Multi-Channel Time Encoding
In this paper, we show that, when using time encoding machines, reconstruction from multiple channels has a more intuitive solution, and does not require the knowledge of the shifts between machines.
Signal Processing
Embedded polarizing filters to separate diffuse and specular reflection
Polarizing filters provide a powerful way to separate diffuse and specular reflection; however, traditional methods rely on several captures and require proper alignment of the filters.
Bound and Conquer: Improving Triangulation by Enforcing Consistency
We study the accuracy of triangulation in multi-camera systems with respect to the number of cameras.
On the Accuracy of Point Localisation in a Circular Camera-Array
Although many advances have been made in light-field and camera-array image processing, there is still a lack of thorough analysis of the localisation accuracy of different multi-camera systems.
SHAPE: Linear-Time Camera Pose Estimation With Quadratic Error-Decay
We propose a novel camera pose estimation or perspective-n-point (PnP) algorithm, based on the idea of consistency regions and half-space intersections.
