This dataset accompanies the paper Gordon, G. S. D., Mouthaan, R., Wilkinson, T. D. & Bohndiek, S. E. Coherent Imaging Through Multicore Fibres with Applications in Endoscopy. J. Light. Technol. 1–1 (2019). doi:10.1109/JLT.2019.2932901
Description:
Each folder is named by a number which represents the total absolute curvature of the fibre (units mm^-1). Inside each, the transferMat_L1.mat file contains the full transmission matrix in MATLAB format. The CAL folder contains the savedResults.mat file which records the rotation, scale and coordinates of the fibre in that particular experiment. In the REFIM folder is a file procesedImages.mat that contains a raw test image that can be reconstructed using the provided transmission matrices.
The folder 'input' contains images of the different input fields used for calibration and should be moved into the 13.472 folder
Instructions:
Using MATLAB R2014a or newer, run compressLargeTMat_blind_multi.m to excecute the algorithm of Figure 2. This compresses the large raw matrices (files transferMat_L1.mat) into compressed versions (transerMat_red_blind_nonuni.mat or similar). This file also generates matrices of Figure 3 of the above paper.
Run examineEigs.m to reproduce plots in Fig 3 and also the eigenvalue and vector analysis of Figre 4.
Run examineCrossCorr.m to examine cross-correlation between the transmission matrices of the fibre under different bending conditions.
