Light-sensing at depth

Nature Reviews Neuroscience, 2020
In mice, neuronally expressed opsin 5 acts as a deep brain violet light detector that allows hypothalamic neuron-mediated inhibition of thermogenesis.

Depth sensing with focus and exposure adaptation

2012 Visual Communications and Image Processing, 2012
Automatic focus and exposure are the key components in digital cameras nowadays, which jointly play an essential role for capturing a high quality image. In this paper, we make an attempt to address these two challenging issues for future depth cameras.

A New Sense for Depth of Field

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1987
This paper examines a novel source of depth information: focal gradients resulting from the limited depth of field inherent in most optical systems. Previously, autofocus schemes have used depth of field to measured depth by searching for the lens setting that gives the best focus, repeating this search separately for each image point.

Extending the depth of field of imaging systems using depth sensing camera

Signal, Image and Video Processing, 2022
© 2022, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.Due to the physical properties of the imaging systems, images obtained by them can be suffered from the limited depth of field. In this work, an efficient approach based on the depth map of the scene for extending the depth field of the imaging ...

Trace-back Depth in Distributed Sensing HMM

2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018
This work addresses the problem of presence detection as Distributed Sensing of a Hidden Markov Model (DS-HMM). We propose an efficient communication strategy to limit sensor communication. For optimum detection under constrained communication, it does not suffice to just send only the latest sensor observations.

Depth sensing capabilities of an interoperative impedance sensing probe

2024 46th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC)
Providing information on the depth of positive surgical margins and important underlying anatomic features would help guide surgeons to resect tissue to negative margins, while sparing healthy tissue needed to preserve function. In transoral robotic surgery, surgeons lack haptic feedback which would be used to locate tumor boundaries and underlying ...
