Projects: Novel Cameras
- An end-to-end camera design method that co-designs cameras with perception tasks
- We combine derivative-free and gradient-based optimizers and support continuous and discrete parameters
- A camera simulation including virtual environments and a physics-based noise model
- Key step in simplifying the process of designing cameras for robots
- Robotic vision without capturing images or allowing image reconstruction
- We propose guidelines and demonstrate localisation in simulation
- Call to action for advancing inherently private vision systems
- Try the reconstruction challenge!
- Automatically interpreting new cameras by jointly learning novel view sythesis, odometry, and a camera model
- A hypernetwork allows training with a wealth of existing cameras and datasets
- A semi-supervised light field network adapts to newly introduced cameras
- This work is a key step to automated integration of emerging camera technologies
- Unsupervised learning of odometry and depth from sparse 4D light fields
- Encoding sparse LFs for consumption by 2D CNNs for odometry and shape estimation
- Toward unsupervised interpretation of general LF cameras and new imaging devices
- Fast classification of visually similar objects using multiplexed illumination
- Using light stage capture and rendering to drive optimization of multiplexing codes
- Outperforms naive and conventional multiplexing patterns in accuracy and speed
- 138° 72 Mpix LF panoramas through a single, spherical lens
- Spherical parameterization compatible with planar light fields

Exploiting parallax in panoramic capture to construct light fields
- We show that parallax, usually considered a nuisance, can be exploited to build light fields
- We turn an Ocular Robotics camera pointing system into an adaptive light field camera
- We demonstrate light field capture, refocusing and low-light image enhancement
- Best paper award, ACRA 2014
