Shape features

Definition

Shape features refer to the distinct geometric characteristics of objects that are discernible in imaging data. These features play a crucial role in the analysis and interpretation of images, particularly in systems that utilize Terahertz (THz) technology, where identifying shapes helps distinguish between different materials and structures.
