Abstract:
Inspection of fabrics is a major consideration in fabric manufacture, as well as in
manufacture of garments and other fabric-based goods. In this research, a computer-based
system for objective assessment of fabric defects was designed with emphasis placed on
fabric defects occurring in the Sri Lankan industry. Image processing techniques were used
to analyse scanned images of the test fabric, compare it with an ideal sample, and identify
defects according to pre-learnt rules. The information gathered was then used to grade the
fabric, either by determining the frequency of defect occurrence or assigning points.
A new classification method for common defects was designed, thereby facilitating grading
according to commonly used grading systems. A coding system for defects was also
designed to help report defects to the user. The fabric defects were classified and stored
according to the developed classification method and coding system.
