Abstract: We prove that a smooth convex body of diameter $$\delta < \frac{\pi }{2}$$ δ < π 2 on the d -dimensional unit sphere $$S^d$$ S d is of constant diameter $$\delta $$ δ if and… read more here.

Abstract: Abstract In perspective projection images, apparent contours are important bases for recovering the three-dimensional (3D) shapes of constant diameter pipes (CDP). In order to complete the 3D reconstruction of CDP under perspective projection, this article… read more here.
