# 水果分类 fruit-classifer
基于深度学习的水果分类
本项目使用迁移学习技术,对在ImageNet数据集上带有预训练权重VGG16、ResNet50、MobileNetV2、DenseNet121模型进行微调,然后将其用在水果数据集上。最终训练后的模型能够准确对输入图片进行分类,并且最高准确率达到93.08%。
#### 一、数据集制作
##### 1.1爬虫获取数据
```python
FRUIT_CLASS = {
'苹果': '01',
'香蕉': '02',
'桃子': '03',
'葡萄': '04'
}
#spider.py实现本功能
```
##### 1.2手动删除不相关图片
##### 1.3数据增强扩充数据集
```python
def Brightness(root_path, img_name): #亮度增强
def Contrast(root_path, img_name): #对比度增强
def crop(root_path, img_name): #随机裁剪
def flip(root_path, img_name): #左右翻转
def rotation(root_path, img_name): #随机旋转
#createImage.py ImageEnhance.py实现本功能
```
#### 二、模型训练
##### 2.1迁移学习
```python
# 模型加载,指定图片处理的大小和是否进行迁移学习
def my_densenet():
IMG_SHAPE = (224, 224, 3)
# 选择base model
base_model = tf.keras.applications.MobileNetV2(include_top=False, weights='imagenet', input_shape=IMG_SHAPE)
base_model.trainable = False
model = tf.keras.models.Sequential([
# 输入层,shape为(None,224,224,3)
tf.keras.layers.Input((224, 224, 3)),
# 输入到base_model中
base_model,
# 将base_model的输出展平,以作为全连接层的输入
tf.keras.layers.Flatten(),
# BN层
tf.keras.layers.BatchNormalization(),
# 输出层,为了保证输出结果的稳定,这里就不添加Dropout层了
tf.keras.layers.Dense(settings.CLASS_NUM, activation=tf.nn.softmax)
])
return model
#models.py实现本功能
```
##### 2.2模型训练
```python
# settings.py 参数设置
# data.py 数据预处理
# train.py 训练模型
```
#### 三、系统实现
设计并实现前后端分离系统,前端Vue,后端Flask
后端模型对输入图片识别并返回用户
运行app.py在本地计算机使用系统,地址为http://192.168.1.29:5000/
