One shape in the edgeoscopy method is compared to another based on what criteria?

In the edgeoscopy method, the primary focus when comparing one shape to another is on consistency or inconsistency. This technique is used in fingerprint analysis to examine the unique characteristics of edge shapes, particularly within latent fingerprints. By assessing the consistency of these shapes, examiners can determine how closely two edges match in terms of their patterns, which is crucial for identifying whether they belong to the same individual.

The consistency criterion allows for a nuanced analysis where even slight variations can be observed and interpreted, enhancing the reliability of the comparison. Identifying inconsistencies may further help in determining the difference between two prints. This approach emphasizes the intricate details of the shapes and their arrangement, which is key to the methodology of edgeoscopy.

Other criteria such as freedom from defects, size and color matching, or historical accuracy do not focus specifically on the detailed characteristics and variations of edge shapes in the same way, thus making them less relevant for this particular comparison method.
