Schematic description of the image processing algorithm developed for the proposed UOM bio-platform. Note that (i) shows the single reference image \((I_{r} )\) with the corrugated optical pattern and the threshold line, (ii) represents profiles of the red pixel intensity \(\left( {P_{i} } \right)\) and the reference profile \(\left( {P_{r} } \right)\) and (iii) illustrates the calibration curve of the proposed BioMEMS sensor plotted by position shifts of the red pixel intensity profiles (due to various concentrations).
