Curvelet transform and its application in image retrieval

Abstract

According to the definition of a curvelet, it is more suitable for image processing than the wavelet and able to represent both smooth and edge parts of image with sparsity. In addition, the representation contains more directional information. The primary experimental results available at present show its potential in image processing. In this paper, we first introduce the concept of curved transform. Then, we propose an image retrieval scheme based on curvelet transform. The experimental results and relevant conclusion are given finally.
