This repository contains files for image analysis, written in MATLAB, based on the Environmental Light Field (ELF) system developed by Smolka & Nilsson (D.-E. Nilsson, J. Smolka, 2021 Quantifying biologically essential aspects of environmental light. J. R. Soc. Interface 18: 20210184). Image data (.mat files) are available from Figshare.
ELF was developed by J Smolka and D-E Nilsson. All ELF scripts written by J Smolka with conceptual input from D-E Nilsson. skypipe.m, rotimdiffsky.m, hmax.m and colourmapsky.m written by JJ Foster.
Requires only a standard computer with enough RAM to support the in-memory operations.
All analysis was performed on macOS: High Sierra (10.13.1) – Catalina (10.15.5)
Curve Fitting Toolbox
