Satellite Image Classification 🚀 This project aims to classify satellite images into four categories: cloudy areas, deserts, green areas, and bodies of water. Using Convolutional Neural Networks (CNN), the project addresses the problem of land cover analysis, providing valuable insights into ecosyste...

Image Classification using CNNFarhana SultanaA SufianParamartha Dutta
Let’s now build a food classification CNN using a food dataset. The dataset contains over a hundred thousand images belonging to 101 classes. Loading the images The first step is to download and extract the data. !wget --no-check-certificate \ http://data.vision.ee.ethz.ch/cvl/food...
这篇论文是剖析 CNN 领域的经典之作,也是入门 CNN 的必读论文。作者训练了一个面向数量为 1.2 百万的高分辨率的图像数据集 ImageNet, 图像的种类为 1000 种的深度卷积神经网络。 ImageNet Classification with Deep Convolutional Neural Networks基于深卷积神经网络的图像网络分类 ...
采用非线性函数:Sigmoid, ReLU(修正线性单元,CNN必用激活函数) 右ReLU有效解决梯度消失(左两侧斜率近乎为零,看的出来吧) 二、池化层 作用:特征融合,降维(无参数需要学习,此处的降维是指减小尺寸,特征层的层数由卷积核数决定了) 引入超参数描述池化:
2)除了频谱和空间信息外,所提出的CNN分类结构利用提取到原始HSI立方体中的语义特征,具有对不同类别的区分能力,同时探索了卷积特征和语义上下文信息。 3) 采用更简单的CNN网络进行HSI分类,并设计反卷积层来增强深度特征,提高分类框架的鲁棒性。 主要部件介绍 ...
