| Abstract(in English) | Images commonly contain some illumination artifacts. When we apply object recognition algorithms for those images, the performance may decrease. To remove the illumination artifact, methods that use empirical mode decomposition (EMD) have been introduced. The EMD provides an adaptive decomposition that decomposes a signal into the so-called intrinsic mode functions (IMFs) and the residue. The residue can be regarded as a component representing the illumination artifact to be removed. However, these methods can lose shades of objects in the original image. In this paper, we propose a method that does not discard the residue but rescale the residue. Experimental results support the analysis. |
