摘　　要：针对传统医学超声图像去斑方法的不足,该文提出一种自适应多曝光融合框架和前馈卷积神经网络模型图像去斑方法。首先,制作超声图像训练数据集;然后,提出一种自适应增强因子的多曝光融合框架,增强图像进行有效特征提取;最后,通过网络训练去斑模型并获得去斑后的图像。实验结果表明,该文较已有的方法,能更有效地滤除医学超声图像中的斑点噪声并更多的保留图像细节。Considering the shortage of traditional medical ultrasound image despeckle methods, an adaptive multi-exposure fusion framework and feedforward convolutional neural network model image despeckle method is proposed. Firstly, an ultrasound image training data set is produced. Then, a multi-exposure fusion framework with adaptive enhancement factors is proposed to enhance the image for effective feature extraction.Finally, a speckle model is trained through the network and a speckle image is obtained.Experimental results show that, compared with the existing methods, this paper can more effectively remove speckle noise in medical ultrasound images and retain more image details.
