Na Wei · Mini-micro Systems · 2005
How to extract feature from Fourier power spectrum to get additional information and how to select feasible similarity measurement are the key problems in frequency domain based image retrieval. Evaluated and analyzed two groups of features, which are based on the fourier frequency spectrum. The method is used in a medical image database developed by institute of visualization technology in Northwest University, it proves that using the approach opposed in the paper can get better results.
