摘要：This paper presents an adaptive image enhancement method through fuzzy set based on speckle detection and contrast enhancement for ultrasound images. The main idea is to enhance the tissue structure and also smooth the speckle regions adaptively from pre-defined fuzzification techniques and radon transform. We firstly fuzzy the original image by S function which can be determined by the maximum entropy principle. Subsequently, we apply the radon transform and add in a filter of triangular function for removing unnecessary signal. Big similarity values means speckle pixels needed smoothing from low pass filtering, and small values correspond to structure pixels. Test images show that our new method can enhance tissue structure and also reduce speckle for better image quality.
