Morphological Reconstruction Operation for the Detection of Defects in Woven Fabric

Basic morphological processing i.e. erosion and dilation, often fails to detect various types of defects that may be present in woven fabric, mainly because of the presence of interlaced grating structure of the weft and warp of the fabric. In this paper basic grating structure is optically filtered and then gray scale morphological reconstruction operations are applied for the detection of defects. The results have shown the usefulness of the proposed method during detections of various types of defects in woven fabric, as illustrated by the portions given in this document.
