Abstract: To generate an all in focus image, the Shape-From-Focus (SFF) is used. The SFF key is finding the optimal focus depth at each pixel or area in an image within sequence of images. In this paper two new focusing measure operators are suggested to be used for SFF. The suggested operators are based on modification for the state of art tool for time-frequency analysis, the Stockwell Transform (ST). The first operator depends on Discrete Orthogonal Stockwell Transform (DOST) which represents a pared version of ST, while the other depends on Pixelwise DOST (P-DOST) which provides a local spatial frequency description. Both of the operators provides the computational complexity and memory demand efficiency compared to the operator depending on ST. A comparison between the suggested operators to operators based on ST are performed and showed that the suggested operators’ performances are as analogous to that of ST.
