Deep Optical Cryptography: Joint Encryption and LC Lens Key Generation for Secure Displays

Journal of the Society for Information Display, EarlyView.
We propose a learning‐based visual cryptography system using a liquid crystal modulator for distance‐dependent optical decryption. By jointly optimizing ciphertext images and LC‐based optical keys with shift‐aware training, the framework ensures secure plaintext recovery only at designated distances.

XStreamVGGT: Extremely Memory‐Efficient Streaming Vision Geometry Grounded Transformer With KV Cache Compression

Journal of the Society for Information Display, EarlyView.
XStreamVGGT enables memory‐efficient streaming 3D inference by jointly pruning and quantizing the KV cache. It reduces memory by 4.42× and accelerates inference by 5.48×, with negligible performance loss on depth, reconstruction, and pose estimation, overcoming the unbounded cache growth of StreamVGGT.

Adaptive Display White Point Under Various Ambient Conditions. Part 2: Dual Illumination

Journal of the Society for Information Display, EarlyView.
This study was designed to investigate how an adaptive display white point should be adjusted under different foreground‐background illumination conditions. It was found that the background illumination had a more significant effect. ABSTRACT Adaptive displays are designed to enhance the user viewing experience by dynamically responding to ambient ...

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

Limnology and Oceanography: Methods, EarlyView.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Red, green, blue color indices as proxy for Symbiodiniaceae cell density and chlorophyll content during coral bleaching

Limnology and Oceanography: Methods, EarlyView.
Abstract Coral bleaching, the breakdown of the symbiosis between the coral host and endosymbiotic microalgae, is the main cause of widespread coral reef degradation. Current visual assessment methods for coral health, including color reference cards, are constrained by subjective human color perception and limited resolution.

A machine learning assisted method for rapidly annotating benthic megafauna in large volumes of marine imagery

Limnology and Oceanography: Methods, EarlyView.
Abstract Recent technological advancements have rapidly expanded our capacity for collecting image data in the marine environment, but processing images into meaningful ecological metrics remains a manual, time‐consuming, and biased process. This is particularly challenging with electro‐optical cabled imaging systems which generate images at a rate ...
