技術摘要 / Abstract


A non-uniform image defect inspection method includes steps of inputting an original two-dimensional image; separating a non-uniform background image from the original two-dimensional image by Discrete Cosine Transform (DCT) to obtain a residual image without the non-uniform background image; binarization segmenting the residual image to extract defects from the residual image, wherein the segmented defects are the inspection results.
