This paper presents a study of content based image retrieval using compression based methods with original and despeckled TerraSAR-X images. This study aims at analysing the behaviour of our method regarding speckle noise. Our method is based on Lempel-Ziv-Welch compression algorithm for feature extraction and fast compression distance as similarity metric. From the experimental results can be observed that the method is independent of the speckle noise.
