Abstract
Some of the most important problems reported when performing Surface Plasmon Resonance Imaging (SPRI)
measurements with modular systems consist in image imperfections. Finding a solution to this challenging aspect is
essential since the reproducibility and the sensitivity of the method are based on an accurate image analysis. The aim of this
paper is to compare some simple algorithms to improve the quality and the amount of information in an SPR image. Two
sections are highlighted: noise reduction and combination of information. The first one deals with the improvement of the
contrast in the images (this means, difference of intensity between spots and background) and the second one with the
possibility of combining the information obtained through two different images in a single one by using a false-colour system.
