Neural compression for hologram images and videos

Optics Letters, 2022
Holographic near-eye displays can deliver high-quality three-dimensional (3D) imagery with focus cues. However, the content resolution required to simultaneously support a wide field of view and a sufficiently large eyebox is enormous. The consequent data storage and streaming overheads pose a big challenge for practical virtual and augmented reality ...

Image and video compression

IEEE Potentials, 1998
The authors discuss the underlying principles of image and video compression. The network model they use for image compression is the random neural network (RNN). This pulsed network model provides a somewhat more accurate representation of what occurs in "real" neurons. Signals in the form of pulse trains travel between neurons.

Compressive video sensors using multichannel imagers

Applied Optics, 2010
We explore the possibilities of obtaining compression in video through modified sampling strategies using multichannel imaging systems. The redundancies in video streams are exploited through compressive sampling schemes to achieve low power and low complexity video sensors.

IMAGE AND VIDEO COMPRESSION: A REVIEW

International Journal of High Speed Electronics and Systems, 1997
The area of image and video compression has made tremendous progress over the last several decades. The successes in image compression are due to advances and better understanding of waveform coding methods which take advantage of the signal statistics, perceptual methods which take advantage of psychovisual properties of the human visual system (HVS)

Multi-Plane Image Video Compression

2020 IEEE 22nd International Workshop on Multimedia Signal Processing (MMSP), 2020
Multiplane Images (MPI) is a new approach for storing volumetric content. MPI represents a 3D scene within a view frustum with typically 32 planes of texture and transparency information per camera. MPI literature to date has been focused on still images but applying MPI to video will require substantial compression in order to be viable for real world

Temporal compressive imaging for video

2017 International Conference on Optical Instruments and Technology: Optoelectronic Imaging/Spectroscopy and Signal Processing Technology, 2018
In many situations, imagers are required to have higher imaging speed, such as gunpowder blasting analysis and observing high-speed biology phenomena. However, measuring high-speed video is a challenge to camera design, especially, in infrared spectrum.
