Using AM-FM Image Modeling Technique in Mammograms
Mona Y. Elshinawy, Mohamed Chouikha · 2006
This paper represents preliminary results for a full study that tries to answer the following question, how well AM-FM modeling technique will behave when applied to mammograms. Our results thus far show that the AM-FM modeling technique yields good results when the images used are mammogram The AM-FM modeling technique consists of three main steps. The first step is applied in this paper, which is, passing the image under study through a bank of Gabor filters. These filters are band pass filters. We used 40 filters arranged as eight rays with 5 filters per ray. Each with has its angle with different center frequencies. The conducted experiments show that by adding up the filtered image from all the filters in the bank, the original image can be observed. This means that Gabor filter banks can work for mammograms and the future work will concentrate on applying the suitable AM-FM modeling technique to detect the region of interest on mammograms.
