Application of PCA in Color-based Feature Extraction of Image
Xiaofei Zhang, Peng Liu · Journal of Shenyang University · 2006
A method for image retrieval based on HSV color model is proposed.The application of PCA in color-based feature extraction of image is used.The number of dimensions of the feature is effectively reduced;the size of the feature database is decreased.When SVM is used to test the classification,better result is obtained.This method will establish a good basement for image retrieval.
