Abstract (in Japanese) (See Japanese page) 
(in English) It is possible for humans to estimate the gradients of the depth direction of the object in monocular. Some researchers proposed estimation methods which were just based on image processing. In this paper, we propose a method to estimate the gradients close to human visual processing. For verification of method, we estimated the gradients of skew symmetric shapes (symmetric shape tilted in the direction of depth). This model calculate asymmetry of the outline of the shapes by neural network model. It regards this value as features. It calculated the features on square which rotated around the horizontal axis, vertical axis, and depth axis. Then, it learned the features by multilayer perceptron using error back propagation method. Thereafter, it estimated the gradients of other shapes after learning square. As a result, this model could estimate the gradients at 8.21 degrees average error on rectangle, at 6.47 degrees on trapezoid, and at 22.20 degrees on teardrop-shapes, respectively.
