ABSTRACT

In this paper, we proposed a new multi node cooperate image compression algorithm for wireless network based on LBT model. Firstly, the visual words of query image are built by using the K-means clustering method after the color features and SIFT features of query image are extracted. Then, the visual-words histogram of the query image is carried out by the mobile agent. The image similarity in each node is measured by the Euclidean distance. At last, experiments were adopted to emulate and validate standard images. Results of experiments show that the compression rate of images has been improved within a large compression scope.
