Abstract

In this paper, extending the depth of focus from microscopy images is investigated by using multi-focus image fusion techniques. The principle of image fusion based on depth of focus is analyzed, and comparisons of different spatial domain fusion methods are given. Furthermore, a multi-focus micro-image fusion algorithm based on area wavelet transform, which offers improved performance over the existing algorithms, is studied and presented. The performance of the spatial domain and wavelet-based algorithms is compared. Advantages and disadvantages of this algorithm are analyzed by experiments, and the main features of this algorithm are summarized and applicable areas are suggested.
