裁剪二维图层裁剪到错误的尺寸

Question

我有一个1920×1153×3keras张量，需要裁剪成1920×1080。但是，创建裁剪层并传递形状的差异会给它错误的尺寸。这种方法给出了1920×1920张量的形状。你知道吗

代码：

        def crop(x, size):
            shape = K.int_shape(x)
            shape_diff = shape[1] - size[1], shape[2] - size[2]
            print(shape_diff)
            y = tf.keras.layers.Cropping2D(shape_diff)(x)
            return y

部分输出型号.概要形状差异：

形状差异： (0,72)

你知道吗型号.概要地址：

Answer 1

通过将边除以2来解决这一问题，因为Keras文件规定：

If tuple of 2 ints: interpreted as two different symmetric cropping values for height and width.
