Compressive Video Acquisition with Multiple Sensors and No Reference Frames

• Standard large-sensor-array-based camera designs are uneconomical when imaging with exotic wavelengths that require expensive photodetectors. The single-pixel camera allows image acquisition with only one sensor; however, its compressive sampling rate is too low to reliably acquire video signals. Hence, we consider the problem of compressive video acquisition with just a few sensors. We propose a block-based framework featuring two sensor modes that does not require the periodic collection of reference frames. We use a joint-sparse signal model to exploit temporal correlations in the video signal, and we explore the behaviour of our framework under different sampling conditions.
