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Caltech101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。

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)+".h5") print file_name if os.path.exists(file_name): #判断之前是否有存到文件中 f = h5py.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 = h5py.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 #Caltech101为102 cifar10为10 pic_dir_out = '/home/ccuux3/pic_cnn/pic_out/' pic_dir_data = '/home/ccuux3/pic_cnn/pic_dataset/Caltech101/' 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("Caltech101_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'+'.h5') if os.path.exists(file_name): f = h5py.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 = h5py.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_Caltech101_resnet50_'+cm_str+'.h5')) model.fit(resnet50_train_output, y_train, epochs=10, batch_size=128,) model.save_weights(os.path.join(pic_dir_mine,'cnn_model_Caltech101_resnet50_'+cm2_str+'.h5'))
测试图像数据集:
(X_test, y_test) = get_data("Caltech101_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'+'.h5') if os.path.exists(file_name): f = h5py.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 = h5py.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]))

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
