✦ Synopsis

A method for automatic image analysis of coke texture has been developed. The method uses an optical polarizing reflecting light microscope, with automatic sample movement. A series of images sized 405 X 270 mm is captured using a CCD video camera. These images are subdivided into six squares at 135 X 135 mm each. For each of these squares an image dis is g laying the contours of the optical domains is made. Tlus contour image ased on either thresholding or a grey level gradient. The structure is then characterized by the mean density and preferred direction of the contours in these square images.
