这篇文章主要为大家展示了如何使用Keras预训练模型ResNet50进行图像分类，内容简而易懂，希望大家可以学习一下，学习完之后肯定会有收获的，下面让小编带大家一起来看看吧。

Keras提供了一些用ImageNet训练过的模型：Xception，VGG16，VGG19，ResNet50，InceptionV3。在使用这些模型的时候，有一个参数include_top表示是否包含模型顶部的全连接层，如果包含，则可以将图像分为ImageNet中的1000类，如果不包含，则可以利用这些参数来做一些定制的事情。

在运行时自动下载有可能会失败，需要去网站中手动下载，放在“~/.keras/models/”中，使用WinPython则在“settings/.keras/models/”中。

修正：表示当前是训练模式还是测试模式的参数K.learning_phase()文中表述和使用有误，在该函数说明中可以看到：

The learning phase flag is a bool tensor (0 = test, 1 = train)，所以0是测试模式，1是训练模式，部分网络结构下两者有差别。

这里使用ResNet50预训练模型，对Caltech201数据集进行图像分类。只有CPU，运行较慢，但是在训练集固定的情况下，较慢的过程只需要运行一次。

该预训练模型的中文文档介绍在http://keras-cn.readthedocs.io/en/latest/other/application/#resnet50。

我使用的版本：

1.Ubuntu 16.04.3

2.Python 2.7

3.Keras 2.0.8

4.Tensoflow 1.3.0

5.Numpy 1.13.1

6.python-opencv 2.4.9.1+dfsg-1.5ubuntu1

7.h6py 2.7.0

从文件夹中提取图像数据的方式：

函数：

def eachFile(filepath): #将目录内的文件名放入列表中 pathDir = os.listdir(filepath) out = [] for allDir in pathDir: child = allDir.decode('gbk') # .decode('gbk')是解决中文显示乱码问题 out.append(child) return out def get_data(data_name,train_left=0.0,train_right=0.7,train_all=0.7,resize=True,data_format=None,t=''): #从文件夹中获取图像数据 file_name = os.path.join(pic_dir_out,data_name+t+'_'+str(train_left)+'_'+str(train_right)+'_'+str(Width)+"X"+str(Height)+".h6") print file_name if os.path.exists(file_name): #判断之前是否有存到文件中 f = h6py.File(file_name,'r') if t=='train': X_train = f['X_train'][:] y_train = f['y_train'][:] f.close() return (X_train, y_train) elif t=='test': X_test = f['X_test'][:] y_test = f['y_test'][:] f.close() return (X_test, y_test) else: return data_format = conv_utils.normalize_data_format(data_format) pic_dir_set = eachFile(pic_dir_data) X_train = [] y_train = [] X_test = [] y_test = [] label = 0 for pic_dir in pic_dir_set: print pic_dir_data+pic_dir if not os.path.isdir(os.path.join(pic_dir_data,pic_dir)): continue pic_set = eachFile(os.path.join(pic_dir_data,pic_dir)) pic_index = 0 train_count = int(len(pic_set)*train_all) train_l = int(len(pic_set)*train_left) train_r = int(len(pic_set)*train_right) for pic_name in pic_set: if not os.path.isfile(os.path.join(pic_dir_data,pic_dir,pic_name)): continue img = cv2.imread(os.path.join(pic_dir_data,pic_dir,pic_name)) if img is None: continue if (resize): img = cv2.resize(img,(Width,Height)) img = img.reshape(-1,Width,Height,3) if (pic_index < train_count): if t=='train': if (pic_index >= train_l and pic_index < train_r): X_train.append(img) y_train.append(label) else: if t=='test': X_test.append(img) y_test.append(label) pic_index += 1 if len(pic_set) <> 0: label += 1 f = h6py.File(file_name,'w') if t=='train': X_train = np.concatenate(X_train,axis=0) y_train = np.array(y_train) f.create_dataset('X_train', data = X_train) f.create_dataset('y_train', data = y_train) f.close() return (X_train, y_train) elif t=='test': X_test = np.concatenate(X_test,axis=0) y_test = np.array(y_test) f.create_dataset('X_test', data = X_test) f.create_dataset('y_test', data = y_test) f.close() return (X_test, y_test) else: return

调用：

global Width, Height, pic_dir_out, pic_dir_data Width = 224 Height = 224 num_classes = 102 #Caltech201为102 cifar10为10 pic_dir_out = '/home/ccuux3/pic_cnn/pic_out/' pic_dir_data = '/home/ccuux3/pic_cnn/pic_dataset/Caltech201/' sub_dir = '224_resnet50/' if not os.path.isdir(os.path.join(pic_dir_out,sub_dir)): os.mkdir(os.path.join(pic_dir_out,sub_dir)) pic_dir_mine = os.path.join(pic_dir_out,sub_dir) (X_train, y_train) = get_data("Caltech201_color_data_",0.0,0.7,data_format='channels_last',t='train') y_train = np_utils.to_categorical(y_train, num_classes)

载入预训练模型ResNet50，并将训练图像经过网络运算得到数据，不包含顶部的全连接层，得到的结果存成文件，以后可以直接调用（由于我内存不够，所以拆分了一下）：

input_tensor = Input(shape=(224, 224, 3)) base_model = ResNet50(input_tensor=input_tensor,include_top=False,weights='imagenet') #base_model = ResNet50(input_tensor=input_tensor,include_top=False,weights=None) get_resnet50_output = K.function([base_model.layers[0].input, K.learning_phase()], [base_model.layers[-1].output]) file_name = os.path.join(pic_dir_mine,'resnet50_train_output'+'.h6') if os.path.exists(file_name): f = h6py.File(file_name,'r') resnet50_train_output = f['resnet50_train_output'][:] f.close() else: resnet50_train_output = [] delta = 10 for i in range(0,len(X_train),delta): print i one_resnet50_train_output = get_resnet50_output([X_train[i:i+delta], 0])[0] resnet50_train_output.append(one_resnet50_train_output) resnet50_train_output = np.concatenate(resnet50_train_output,axis=0) f = h6py.File(file_name,'w') f.create_dataset('resnet50_train_output', data = resnet50_train_output) f.close()

将ResNet50网络产生的结果用于图像分类：

input_tensor = Input(shape=(1, 1, 2048)) x = Flatten()(input_tensor) x = Dense(1024, activation='relu')(x) predictions = Dense(num_classes, activation='softmax')(x) model = Model(inputs=input_tensor, outputs=predictions) model.compile(optimizer=Adam(), loss='categorical_crossentropy',metrics=['accuracy'])

训练图像数据集：

print('\nTraining ------------') #从文件中提取参数，训练后存在新的文件中 cm = 0 #修改这个参数可以多次训练 cm_str = '' if cm==0 else str(cm) cm2_str = '' if (cm+1)==0 else str(cm+1) if cm >= 1: model.load_weights(os.path.join(pic_dir_mine,'cnn_model_Caltech201_resnet50_'+cm_str+'.h6')) model.fit(resnet50_train_output, y_train, epochs=10, batch_size=128,) model.save_weights(os.path.join(pic_dir_mine,'cnn_model_Caltech201_resnet50_'+cm2_str+'.h6'))

测试图像数据集：

(X_test, y_test) = get_data("Caltech201_color_data_",0.0,0.7,data_format='channels_last',t='test') y_test = np_utils.to_categorical(y_test, num_classes) file_name = os.path.join(pic_dir_mine,'resnet50_test_output'+'.h6') if os.path.exists(file_name): f = h6py.File(file_name,'r') resnet50_test_output = f['resnet50_test_output'][:] f.close() else: resnet50_test_output = [] delta = 10 for i in range(0,len(X_test),delta): print i one_resnet50_test_output = get_resnet50_output([X_test[i:i+delta], 0])[0] resnet50_test_output.append(one_resnet50_test_output) resnet50_test_output = np.concatenate(resnet50_test_output,axis=0) f = h6py.File(file_name,'w') f.create_dataset('resnet50_test_output', data = resnet50_test_output) f.close() print('\nTesting ------------') #对测试集进行评估 class_name_list = get_name_list(pic_dir_data) #获取top-N的每类的准确率 pred = model.predict(resnet50_test_output, batch_size=32)

输出测试集各类别top-5的准确率：

N = 5 pred_list = [] for row in pred: pred_list.append(row.argsort()[-N:][::-1]) #获取最大的N个值的下标 pred_array = np.array(pred_list) test_arg = np.argmax(y_test,axis=1) class_count = [0 for _ in xrange(num_classes)] class_acc = [0 for _ in xrange(num_classes)] for i in xrange(len(test_arg)): class_count[test_arg[i]] += 1 if test_arg[i] in pred_array[i]: class_acc[test_arg[i]] += 1 print('top-'+str(N)+' all acc:',str(sum(class_acc))+'/'+str(len(test_arg)),sum(class_acc)/float(len(test_arg))) for i in xrange(num_classes): print (i, class_name_list[i], 'acc: '+str(class_acc[i])+'/'+str(class_count[i]))
