First, the data is mapped into a higher-dimensional space with kernel principal component analysis to make the data linearly separable. Then a two-layer KPCANet is built to obtain the principal components of the image. Finally, the principal components are classified with a linear classifier. Experimental results showthat the proposed KPCANet is effective in face recognition, object recognition and handwritten digit recognition. It also outperforms principal component analysis network( PCANet) generally. Besides, KPCANet is invariant to illumination and stable to occlusion and slight deformation.展开更多

The conventional X-ray approacheshave some shortcomings, such as the need to make use of a dye-product and basisprojective-integrative rule for the image formation. On the one hand, the patient hasto suffer a great radiation dose, and a registration process is also often needed to cor-rect the displacement bias between the images due to the patient’s movements.
