Abstract

Several image analysis techniques were applied to a colorimetric chemical sensor array called DETECHIP®. Analytes such as illegal and over the counter drugs can be detected and identified by digital image analysis. Jpeg images of DETECHIP® arrays with and without analytes were obtained using a camera and a simple flatbed scanner. Color information was obtained by measuring red-green-blue (RGB) values with image software like GIMP, Photoshop, and ImageJ. Several image analysis methods were evaluated for analysis of both photographs and scanned images of DETECHIP®. We determined that when compared to photographs, scanned images of DETECHIP® gave better results through the elimination of parallax and shading that lead to inconsistent results. Furthermore, results using an ImageJ macro technique showed improved consistency versus the previous method when human eyesight was used as a detection method.
