A visual pattern recognizing method was applied to the evaluation of the fabric structures.
This paper describes a system using pattern-recognition techniques and picture processing techniques.
The pattern of fabrics is read by a two-dimensional optical-electric sensor connected to a digital computer and is represented by a two-dimensional array of points showing the transparency distribution of fabrics.
The computer extracts the feature information from pattern of fabrics using the concept of “Cell”. The cells are divided into five gray levels according to the threshold logic to separate the abnormal region from the normal and to classify the abnormal.
