Attributes Reduction Applied to Leather Defects Classification

2010 23rd SIBGRAPI Conference on Graphics, Patterns and Images, 2010
This paper presents a study on attributes reduction, comparing five discriminant analysis techniques: FisherFace, CLDA, DLDA, YLDA and KLDA. Attributes reduction has been applied to the problem of leather defect classification using four different classifiers: C4.5, kNN, Na\"{i}ve Bayes and Support Vector Machines. The results of several experiments on

A Robust Real-time Leather Defect Segmentation Using YOLO

2023 18th Iberian Conference on Information Systems and Technologies (CISTI), 2023
Natural leather is a product made from animal skin which is treated through chemical procedure to preserve it. It is used in the manufacture of clothing, bags, furniture, automobile material, among others. Because of its capital value in industry, it is important to ensure its quality.

Defect detection on leather by oriented singularities

1997
This paper presents a system for leather inspection based upon visual textural properties of the material surface. Defects are isolated from the complex and not homogeneous background by analyzing their strongly oriented structure. The patterns to be analyzed are represented in an appropriate parameter space using an optimization approach: in this way ...

Automated defect inspection and classification of leather fabric

Intelligent Data Analysis, 2001
This paper describes an automated vision system for detecting and classifying surface defects on leather fabric. In the defect inspection process, visual defects are located and reported through a two-step segmentation procedure based on thresholding and morphological processing.

Leather features selection for defects' recognition using fuzzy logic

Proceedings of the 5th international conference on Computer systems and technologies - CompSysTech '04, 2004
In the present work are investigated 12 histogram and statistical features for analysis of leather surface images. A research of the features suitability for surface defects detection is done. For the image analysis was used the quadtree decomposition method - a technique that partitions an image into homogeneous blocks.
