In a single photograph of fabric, it is difficult to observe the fine texture and material properties of the fabric. We propose to reveal the detail texture of fabric by using a sequence of photographs captured by changing the direction of light source. One problem encountered in implementing such approach is how to remove the shadows of the photographic equipment cast on the sequence of fabric images. In this paper, we propose a method to remove shadows on the images by applying Robust PCA to the image sequence with only diffuse reflection components. We compare original images with dimensionally reduced images and verify the effectiveness of our method. |
