Image Processing Techniques for Improved Porosity Estimation
The work reported here is on the first phase of the development of an automated image analysis package. It is intended that the initial application should be to the problem of porosity estimation in powder metals. Although a great deal of work has been concentrated recently on using ultrasonic velocity changes and attenuation for porosity estimation, the problem can also be addressed through acoustical imaging.
