Abstract:

 Image data is high-dimensional data which make it easily prone to the dimension disaster. The traditional dimensionality reduction methods can not recover the
inherent structure. Manifold learning is a nonlinear dimensionality reduction technique, it aims to find low-dimensional compact representations of high-dimensional observation
data and explore the inherent law and intrinsic dimension of data. In this paper, the feature extraction method-SIFT and the adaptive ISOMAP method are combined and conducted on
the real face image dataset. This paper analyzes and discusses the problem of the effects of the neighborhood parameter and the intrinsic dimension size on the face image
recognition.

Key words: image retrieval, manifold learning, dimensionality reduction, intrinsic dimension
