This study aims to explore the potential of detecting impervious surfaces using fully convolutional networks (FCNs) with pre-trained network parameters and high resolution multispectral satellite imagery. Since off-the-shelf pre-trained networks are usually trained with RGB bands, the number of input ...

前面几篇文章介绍了MINIST,对这种简单图片的识别,LeNet-5可以达到99%的识别率。 CIFAR10是另一个著名的深度学习图像分类识别数据集,比MINIST更复杂,而且是RGB彩色图片。 看看较简单的LeNet-5可以达到多少准确率。网络结构基本和前面MINIST代码中的差不多,主要是输入图片的通道数不同,代码如下: ...

This means that this classification model will reduce training time compared with that of the model without segmenting the images. In particular, we applied a VGG-19 model with transfer learning for re-training in later layers. In addition, the parameters such as epoch and learning rate were ...
