On-Device Super-Resolution Imaging for a Low-Cost SPAD Array on a 640-KB-SRAM Microcontroller
Zhenya Zang, Istvan Gyongy, Mike Davies
This work presents a super-resolution (SR) deep-learning (DL) architecture to simultaneously upscale low-resolution (LR) depth and intensity images acquired by a consumer-grade VL5…

Memory- and Bandwidth-Efficient SPAD-LiDAR Ranging via Coarse-to-Fine Spline Sketching
Zhenya Zang, Zhenya Zangy, Istvan Gyongy +1
This work presents an optimized compression framework for direct time-of-flight (dToF) light detection and ranging (LiDAR), using an accurate, compact timestamp-encoding strategy t…

Histogramless Time-Domain Sketched Fluorescence Lifetime Imaging
Zhenya Zang, Istvan Gyongy, Mike Davies
We present a statistics-aware compression strategy that processes photon timestamps directly from time-correlated single-photon counting (TCSPC) modules for time-domain fluorescenc…
