Wavelet Based Sharp Feature Multi-Focus Image Fusion In Dct Domain

Multi focus Image fusion is process of combining information of two or more images of a scene and as significance has "all-in-focus" image. When one section covers objects in different distance, the camera can b1(Student, Department of Electronics and Communication Engg., Punjabi University, Patiala 2(Assistant Professor, Department of Electronics and Communication Engg., Punjabi University, Patialae focused on each object one afterward the other, generating a set of pictures. Now, by image fusion technique, an image with better focus sideways all zone can be produced. There are many multi focus image fusion approaches, today. One of them is Experiential Mode Decay shaped multi focus image fusion. The object of the image fusion is to retain the most desirable characteristics of each image. A multi-focus image fusion approach using a new sharpness criterion that depends on statistics of image's gradient information is proposed in this dissertation. The proposed approach exploits a Discrete Cosine Wavelet criterion to adaptively perform image fusion by selecting most informative (sharp) information from the input images.
