This paper proposes a hybrid algorithm based on improved LLE and adaptive k-means for visual codebook generation in tourism scene classification. Firstly, we construct the improved LLE algorithm to get lower dimensional and compressed image feature representations. Then we form the adaptive k-means clustering algorithm to generate the visual codebook. Finally, we use the visual codebook histogram...
As the size of image databases for various applications keeps growing at an explosive rate, how to automatically and efficiently classify the images and mimic human visual perception is an extremely important issue. The spatial layout information of the image is a kind of abstract semantics and the visual grammar of the image. It could dramatically improve the effectiveness of the scene classification...
