This paper presents an image analysis measurement algorithm – best-fit rectangle for particle size and shape. The best-fit rectangle approach is a combination of the Ferret method and the least 2nd moments minimization, only requiring calculation of three moments about the center of gravity, and maximum and minimum co-ordinates in a co-ordinate system oriented in the direction of the axis of least 2nd moments, and a simple area ratio. It is a simple rotation-invariance method, reflecting shape (Elongation and angularity). The algorithm is introduced theoretically in details, analyzed and compared to other widely used methods, and has been tested by a large number of solid particle samples in a laboratory. The test results show that by using this method, the results are very close to manual measurements.
