Abstract:

When analysing the colourcolours in woven fabrics images, the fabrics are suggested to be divided into three categories: solid colour fabrics, single-system-mélange colour fabrics and double-system-mélange colour fabrics. Corresponding to the classification, the inspection of woven fabric density can be also divided into three stages. A method of inspecting the density of solid colourcolour fabrics is discussed in detail in this study. The Hough transform is used to detect the skew angles of warp and weft yarns, and then the pixels in the fabric image are projected along the skew-direction. Warp and weft yarns can be segmented successfully by locating the true minimum values which indicate the interstices between the yarns. The density of solid colourcolour fabric can be inspected by counting the yarns in a unit length in the fabric image.
