Figure 3

Sample of video frames reconstructed in low light conditions for visible and SWIR wavelengths simultaneously, whilst utilising an iterative and optimisation algorithm. The top and bottom rows respectively show video frames for full-colour (red,green,blue) and SWIR (800–1800 nm). Frames reconstructed using the iterative algorithm (a) show uniform noise across the image compared to frames reconstructed using the optimisation algorithm (b) at the expense of image resolution. Both reconstructions have been fully sampled at 32 × 32 pixel resolution and up-sampled and interpolated to 64 × 64 pixels in real-time with no additional time-lag.
