ABSTRACT
Disintegration and fusion errors caused by less-than-perfect edge-detection occur to a greater or lesser extent in all digital image analysis systems for fragmentation measurement. This paper gives definitions and examples, based on experiments to assess these effects and their cause, including the effects of fragment size, background shade, camera shutter speed and proximity of adjacent fragments. Indexes are defined as a basis for quantifying the amount of disintegration and the “fidelity” of edge detection.
