Abstract

As face recognition algorithms move from research labs to real world product, power consumption and cost become critical issues, and DSP-based implementations become more attractive. Also, “real-time” automatic personal identification system should meet the conflicting dual requirements of accuracy and response time. In addition, it also should be user-friendly. This paper proposes a method of face recognition by the LDA Algorithm with the facial feature extracted by chrominance component in color images. We designed a face recognition system based on a DSP. At first, we apply a lighting compensation algorithm with contrast-limited adaptive histogram equalization to the input image according to the variation of light condition. While we project the face image from the original vector space to a face subspace via PCA , we use the LDA to obtain the best linear classifier. The experimental results with real-time input video show that the algorithm has a pretty good performance on a DSP-based face recognition system. And then, we estimate the Euclidian distances between the input image’s feature vector and trained image’s feature vector.
