Abstract
We propose a method to reconstruct the two-dimensional object from an image captured through an array of random lenses each of which has random shape, size, and focal power. In the proposed method, the characteristics of the random lens array are estimated by capturing images for known elementary inputs, and then the object is reconstructed by measuring correlations between the random lens images of the object and the elementary inputs. The experimental results show that the original object can be recognized by the proposed reconstruction method. Nevertheless, further quality enhancement is required to increase feasibility and to extend to general three-dimensional object cases.
