Depth estimation of an object in a scene from images intensity is an essential problem in machine vision applications. Here, In order to obtain the distance between object and camera, a novel method presented for depth estimation from a single...

to as complex piers. A few studies have been done on complex bridge pier scour depth estimation. Such efforts may be classified into theoretical and empirical equations. This paper investigates local scour around complex bridge piers by using harmony search...

. In addition, the accuracy of recent commonly methods for local scour depth estimation around complex bridge pier were evaluated....
