Abstract
A low cost, personal computer based, image processing system has been developed to automatically analyze and numerically rate deposits on metal surfaces generated in lubricant oxidation stability tests. Such tests are routinely used for evaluating and developing new engine lubricant technology. In many cases it is difficult to effectively and reproducibly evaluate these deposits with manual rating methods. Software has been developed to process images of deposits in two stages. In the first stage the image is segmented to extract the area of deposit. In the second stage image analysis techniques are applied to the extracted region and relevant parameters such as mean darkness, area of deposit and texture of deposit are computed. To compute deposit texture second order grey level statistics are used. These methods are applicable to a variety of lubricant and fuel test procedures.
