Abstract :
In this paper, the three-, the six-, and the eight-parameter two-dimensional gradient based adaptive lattice filters are compared in the context of defect detection in textures corresponding to textile fabrics. A novel histogram modification technique is also applied for preprocessing the gray level texture image. Moreover, with the proposed scheme, it is possible to detect defects in an unsupervised manner
