Perform image processing tasks, such as removing image noise and performing image-to-image translation, using deep neural networks (requires Deep Learning Toolbox™)Deep learning uses neural networks to learn useful representations of features directly from data. For example, you can use a pretraine...
之前主要研究现代信号处理,深度学习嘛,一个大号/深层的,现代的,黑箱的,信号/图像处理器,所以,作为一个研究现代信号处理的,顺便搞些深度学习也是顺理成章的。顺便,本例来自于Mathworks公司的大佬,程序运行环境为MATLAB R2018A。 本文简要讲解如何训练一个经典的降噪卷积神经网络 (DnCNN),并使用DnCNN网络减少JPEG压缩伪...
