tf.keras.applications.imagenet_utils.preprocess_input( x, data_format=None, mode='caffe' ) 参数 x 具有3 个颜色通道的浮点 numpy.array 或tf.Tensor、3D 或 4D,其值在 [0, 255] 范围内。如果数据类型兼容,则预处理数据将覆盖输入数据。为了避免这种行为,可以使用numpy.copy(x)。 data_format 图像张量...
image = image_utils.load_img(args["image"], target_size=(224, 224)) image = image_utils.img_to_array(image) Line 25applies the.load_imgKeras helper function to load our image from disk. We supply atarget_sizeof224 x 224pixels, the required spatial input image dimensions for the VGG1...
preprocess = preprocess_input Here we initialize ourinputShapeto be224×224pixels. We also initialize ourpreprocessfunction to be the standardpreprocess_inputfrom Keras (which performs mean subtraction). However, if we are using Inception or Xception, we need to set theinputShapeto299×299pixels, ...

这里我们初始化inputShape为224×224像素,初始化预处理函数为keras.preprocess_input——执行mean subtraction运算。 如果使用Inception或者Xception,inputShape需要改为299×299像素,预处理函数改为separate pre-processing函数。 下一步就是从磁盘载入网络架构的weights,并实例化模型: ...
