In the realm of Compressed Sensing(CS), Orthogonal Matching Pursuit(OMP) algorithm is widely acknowledged. The generalized Orthogonal Matching Pursuit(gOMP) algorithm is an improved OMP approach. However, it demonstrates low reconstruction accuracy for electron probe images based on our experiments. This paper enhances g OMP by adjusting the algorithm parameters according to the characteristics of electron probe images. An optimal sparsity(K) and the atom selection numbers(S) matching with best parameters for gOMP is selected through experiments. Besides that, Fourier measurement matrix has been identified after evaluation of various measurement matrices. The improved algorithm, Fourier's generalized Orthogonal Matching Pursuit(FgOMP), is constructed based on these findings. The simulation results show that the proposed algorithm can achieve Super Resolution Recovery requirements and provide a significant higher reconstruction quality for electronic probe images than the original g OMP algorithm and other relevant algorithms.
