THE DIRECT USE OF CURVELETS IN MULTIFOCUS FUSION H. Hariharan, A. Koschan and M. Abidi
 

Summary: THE DIRECT USE OF CURVELETS IN MULTIFOCUS FUSION
H. Hariharan, A. Koschan and M. Abidi

University of Tennessee, Knoxville -37996.
ABSTRACT
In this effort, a data-driven and application independent
technique to combine focal information from different focal
planes is presented. Input images, acquired by imaging
systems with limited depth of field, are decomposed using a
relatively new analysis tool called curvelets. The extracted
curvelets are representative of polar `wedges' from the
frequency domain. Fusion is performed on medial and
peripheral curvelets by relevant fusion rules and the fused
image combines information from different focal planes,
while extending the depth of field of the scene. The main
contribution in this effort is the direct use of curvelets in
combining multifocal images. Several illustrative examples
and objective comparisons are provided.
Index Terms-- Multifocus fusion, image fusion,
curvelet transform, extending depth of field
