3-D Range Estimation From the Focus Sharpness of Edges

  • G. Garibotto

In the proposed method the focus sharpness of edge points in a recorded image is used to estimate their actual position in the 3-D space. As a matter of fact, the amount of blurring in a picture depends on the distance of the object details from the plane which is “in focus” in the observed scene. Henceforth, from such measures it is possible to roughly provide depth estimates on strong edges of a recorded image. Moreover, sharpness estimates can be effectively used as additional features of the detected contours in other problems of image registration (stereo and motion). This approach can be used to roughly provide depth estimates on strong edges of a recorded image; some examples are enclosed to show its performance on a set of real scenes.
