Abstract:

For the need of detection of fabric defects, the paper presents an improved algorithm based on differential box-counting (IDBC) method. The algorithm modifies the highness of the boxes, the method of determining the amount of boxes in grids and the statistics of calculating the total of all the boxes on the premise of using Brodatz texture library sample. On the two aspects of the time and accuracy, the paper compared the new algorithm with classical differential box-counting method(DBC) and obtained the efficiency of the improved algorithm. At the same time, the paper calculated defect fabric of the three common texture employing improved differential box-counting method to verify defect fabric. Through four parameters, i.e. detection rate, false drop rate, loss rate and detection precision, the results of experiments demonstrate this new method is effective and can outperform the well-known differential boxing-counting (DBC) method.
