ABSTRACT: This paper presents an innovative method
for digital refocusing of different point in space after capturing and also
extracts all-in-focus image. The proposed method extracts all-in-focus image
using Michelson contrast formula hence, it helps in calculating the coordinates
of the 3D object location. With light field integral camera setup the scene to
capture the objects precisely positioned in a measurable distance from the
camera therefore, it helps in refocusing process to return the original
location where the object is focused; else it will be blurred with less
contrast. The highest contrast values at different points in space can return
the focused points where the objects are initially positioned as a result;
all-in-focus image can also be obtained. Detailed experiments are conducted to
demonstrate the credibility of proposed method with results.
