An Efficient Feature Selection Method For Object Detection
Duy-Dinh Le, Shin’ichi Satoh · 2005
Abstract. We propose a simple yet efficient feature-selection method — based on principle component analysis (PCA) — for SVM-based classifiers. The idea is to select features whose corresponding axes are closest to the principle components computed from a data distribution by PCA. Experimental results show that our proposed method reduces dimensionality similar to PCA, but maintains the original measurement meanings while decreasing the computation time significantly. 1
