Merging Images Through Pattern Decomposition

摘要: It is frequently desirable to combine different sources of image information into a composite prior undertaking analysis. For example, multiple images may be merged extend the field view or resolution, eliminate foreground obstacles. Or stereo combined so that regions occluded in one camera's are filled smoothly with seen by other camera. The essential problem merging "pattern conservation": important details component must preserved while no spurious pattern elements introduced process. Simple approaches often create edge artifacts between taken from source images, and these confound subsequent We describe an approach based on decomposition. Each first transformed set primitive elements. Pattern sets for various then form single image. Finally reconstructed its primitives. illustrate decomposition technique several practical applications. These include objects, depth field. In all cases Laplacian pyramid used encode terms primitives which resemble Gaussians many scales.
