| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this report, we studied a specified method of regions including dislocations which are crystallographic defects in a photoluminescence (PL) image of multicrystalline silicon wafers. We utilized a method of non-negative matrix factorization (NMF) to reconstruct the wafer image. We assumed regions of dislocations caused large represent errors and presented darker colors. We obtained effective results by the proposed method than results of sparse coding methods using bases based on independent component analysis or NMF. Sparse coding methods allow negative values as coefficients matrix. As sample images of the learning process, images without dislocations lead effective results. | |
