In this paper, we present our results when using a Regression Deep Neural Network in an attempt to position the end-effector of a 2 Degrees of Freedom robotic arm to reach the target. We first train the DNN to understand the correspondence between the target position and the joint angles, and then we use the trained neural network to ... WebThe first factor is the relation between aperture and depth of field. In photography, the aperture is linked to the DoF in your image. To put it simply, the larger the aperture you use, the shallower the depth of field will be. On the other hand, the smaller the aperture you use, the greater the depth of field will be in your image.
