In certain embodiments, a system includes a processor and a memory storing machine readable instructions executable by the processor, the machine readable instructions including a seismic image analysis tool having a wavelet packet transformer to generate sub-images of a received seismic image, a sub-image filter to perform noise suppression and edge detection on each sub-image, an inverse wavelet packet transformer to reconstruct higher level sub-images or seismic image from filtered sub-images, and a sub-image merger to recursively merge a sub-image and a reconstructed sub-image.
