1. A method of resistivity imaging, comprising:
disposing a downhole tool into a borehole, wherein the downhole tool comprises:
a pad;
an array of injector electrodes; and
one or more return electrodes;
applying a voltage difference between the array of injector electrodes and the one or more return electrodes with a plurality of frequencies;
making an impedance measurement with the array of injector electrodes for each of the plurality of frequencies;
constructing a first set of formation images and a second set of formation images from the impedance measurement;
combining the first set of formation images and the second set of formation images to form a blended image, wherein at least one or more pixels from the blended image are different than 0, wherein at least one or more pixels from the blended image are different than every pixel from the first set of formation images, and wherein at least one or more pixels from the blended image are different than every pixel from the second set of formation images.
