图像处理领域有很多滤波器，好的滤波器可以很快的提取有效的特征，MR8是一组特别好的滤波器组，比gabor filter更好，这里是MR8的源码，有需要的可以下载一用！(There are a lot of image processing filter, a good filter can quickly extract effective feature, MR8 is a particularly good filter group, better than gabor filter, here is MR8 source, there is a need to download a use!)

Abstract—Noninvasive ultrasound imaging of carotid plaques allows for the development of plaque-image analysis methods associated with the risk of stroke. This paper presents several plaqueimage analysis methods that have been developed over the past years. The paper begins with a review of clinical methods for visual classification that have led to standardized methods for image acquisition, describes methods for image segmentation and denoizing, and provides an overview of the several texture-feature extraction and classification methods that have been applied. We provide a summary of emerging trends in 3-D imaging methods and plaque-motion analysis. Finally, we provide a discussion of the emerging trends and future directions in our concluding remarks.
