资源介绍:

本项目致力于开发和优化手写数字识别系统，利用机器视觉和深度学习技术，旨在提高识别准确率和处理效率。项目包含以下主要内容： 数据集构建： 数据集分为训练集和测试集，每个集分别包含大量手写数字图像，覆盖从0到9的所有数字。图像经过预处理，以确保数据的一致性和质量，为模型训练提供坚实基础。 模型设计与训练： 项目采用卷积神经网络（CNN）进行手写数字识别。CNN 模型通过多层卷积和池化操作，自动提取图像中的特征，并使用全连接层进行分类。 在模型训练过程中，项目应用了多种数据增强技术，如旋转、缩放、平移等，以提高模型的泛化能力。 为了优化模型性能，项目引入了交叉验证和超参数调优技术，确保模型在不同数据集上的稳定表现。 性能评估与测试： 使用独立的测试集对模型进行评估，通过混淆矩阵、准确率、召回率、F1 分数等多种指标全面评估模型的性能。 项目还进行了一系列对比实验，分析不同模型架构、超参数设置对识别效果的影响，找出最优配置。
