This tool provides its user with a single environment for performing the following processes:

• Capture Images - A very intuitive interface enables a user to acquire high-quality images1
• Select a Lens - A pull-down menu allows the user to select from a list of supported lenses
• Define Image Resolution - Pixel size is determined by the user's lens selection so that quantitative measurements are given in real word units
• Compute estimated average size of the grains - This value is computed, according to the ASTM E-112 standard, from the intercepts of the grain boundaries along the test lines. The grain boundaries are automatically extracted using a powerful segmentation technique
• Generate Reports - User modifiable reports are generated that include computation of the average grain size and other basic statistics

The grain sizing process consists of three steps, beginning with automatic detection of grain boundaries using a very fast, real-time algorithm. In the second step, the user defines a set of test lines by specifying the number of equally-spaced lines in the horizontal and vertical directions. In the final step, an estimate of the number of grains intersected by each line is determined by counting the number of intercepts along the lines.
