This study was achieved to find an optimum design for eggs incubator where the resources of this field is very limited. The most important factors were putted forward including dimensions each element. energy required in operation periods calculated. Where time consists two (the first period takes 17 days and second from 18th day 21 day). results shown excellent efficiency, however, some failed...

The distance transform has found many applications in image analysis. The Euclidean distance transform is computationally very intensive, and eecient discrete algorithms based on chamfer metrics are used to obtain its approximations. The chamfer metrics are selected to minimize an approximation error. In this paper, a new approach is developed to nd optimal chamfer local distances. This new app...
