Abstract

This paper deals with the performance evaluation of sparse banded matrix filter applied for Face recognition. Edges extracted using the sparse banded matrix filter (ABFilter) is used as a feature descriptor for face recognition. The classification is done using Random Kitchen Sink which is accessed through GURLS library and also classified using Support Vector Machines (SVM). The experimental evaluation of sparse banded matrix filter is done on a standard face database (Yale). Edge detection is the process of locating the sharp discontinuity in an image. It is a basic tool which is used in many image processing applications such as face recognition. In this paper, we have compared the performance of sparse banded matrix filter with existing edge detecting filters such as Sobel, Prewitt, Canny and Robert. Though many filters exist for edge detection, sparse banded matrix filter is known for the edge detection with minimal discontinuity. The experimental evaluation shows that the edge feature descriptors of Yale face database obtained using sparse banded matrix filter provides 88 % accuracy using GURLS and 81% using SVM.
稀疏带状矩阵滤波提取边缘特征在人脸识别中的性能评价
本文研究了稀疏带状矩阵滤波器在人脸识别中的性能评价。利用稀疏带状矩阵滤波器(ABFilter)提取边缘作为人脸识别的特征描述符。使用随机厨房水槽进行分类,该分类通过GURLS库访问,并使用支持向量机(SVM)进行分类。在标准人脸数据库上对稀疏带状矩阵滤波进行了实验评价。边缘检测是定位图像中明显的不连续点的过程。它是一个基本的工具,用于许多图像处理应用,如人脸识别。本文将稀疏带状矩阵滤波器与现有的Sobel、Prewitt、Canny和Robert等边缘检测滤波器的性能进行了比较。虽然存在许多用于边缘检测的滤波器,但稀疏带状矩阵滤波器以其最小的不连续边缘检测而闻名。实验评估表明,使用稀疏带状矩阵滤波获得的耶鲁人脸数据库边缘特征描述子,使用GURLS和支持向量机分别获得88%和81%的准确率。
