An improved optimal set of statistically uncorrelated discriminant vectors. (Chinese. English summary) Zbl 1240.68262

Summary: Generalizing the Fisher discriminant criterion, this paper presents the concept of the improved optimal set of statistically uncorrelated discriminant criterion. First, a feature is obtained in the linear subspace by using PCA. Then, the optimal set of discriminant vectors is constructed through the application of the improved statistically uncorrelated discriminant criterion. An experiment of facial recognition shows that the improved method is superior to the existing method in terms of correct classification rate.
