Content-based image retrieval (CBIR) technique retrieves relevant images based on extracted features from image contents. Latent semantic indexing (LSI) is used as a semantic model in the CBIR field. This paper investigates the capability of LSI-based CBIR in dealing with different types of image noise, and the impact of noise on the retrieval results. To construct the feature-image matrix (FIM) in...
Proposed a texture analysis method that based on the combination of the Gabor filters and 2DPCA. Through Gabor filter obtained the multi-direction and multi-resolution Gabor sub-image in the time and frequency domains. The Gabor sub-images were processed by 2DPCA, and extracted the multi-scale and multi-orientation feature vector. Finally using Euclidean distance measure the similarity of different...
Recent years, the biometric technology attracts more and more people's attention. However, the single-modal biometric technology is difficult to meet the higher security needs and multi-modal biometric technology gradually becomes the mainstream of biometrics. In this paper, face and palmprint biological characteristics are used for recognition. Gabor transform and Independent Component Analysis (ICA)...
