Two-dimensional inversion results obtained using three electrode arrays, the Wenner, Schlumberger and dipole-dipole synthetic data sets were combined using Algorithm librarian of an image processing program PCI Geomatica widely used for remotely sensed data. The hybrid or combined images which were obtained using, the maximum, minimum, median and average values of the produced inverse models were compared. Image registration was applied in order to establish correspondence and integration between the images. All the images resolved and recovered the essential features of the true models. The images produced bear considerable likeness to the true models. An evaluation of the accuracy of the seven images for the four geologic models was assessed using four criteria via an error measure and the recovered mean resistivity values of the predicted blocks from the true blocks. The results show that the images of maximum approach give the least estimated mean absolute error. Also, the mean resistivity values of the blocks are closest to the true blocks for all the images of maximum method. Thus, it is corroborated that when inverse models are combined, most reliable and detailed information about the geologic models is than using individual inverse models.
