示例1: distort_image
# 需要導入模塊: from preprocessing import inception_preprocessing [as 別名]
# 或者: from preprocessing.inception_preprocessing import distort_color [as 別名]
def distort_image(im, fast_mode=False):
# All images in the same batch are transformed the same way, but over
# iterations you see different distortions.
# im should be float with values between 0 and 1.
im_ = tf.reshape(im, shape=(-1,1,3))
im_ = ip.apply_with_random_selector(
im_, lambda x, ordering: ip.distort_color(x, ordering, fast_mode),
num_cases=4)
im_ = tf.reshape(im_, tf.shape(im))
return im_ 示例2: distort_randomly_image_color
# 需要導入模塊: from preprocessing import inception_preprocessing [as 別名]
# 或者: from preprocessing.inception_preprocessing import distort_color [as 別名]
def distort_randomly_image_color(image_tensor, fast_mode=False):
"""Accepts image tensor of (width, height, 3) and returns color distorted image.
The function performs random brightness, saturation, hue, contrast change as it is performed
for inception model training in TF-Slim (you can find the link below in comments). All the
parameters of random variables were originally preserved. There are two regimes for the function
to work: fast and slow. Slow one performs only saturation and brightness random change is performed.
Parameters
----------
image_tensor : Tensor of size (width, height, 3) of tf.int32 or tf.float
Tensor with image with range [0,255]
fast_mode : boolean
Boolean value representing whether to use fast or slow mode
Returns
-------
img_float_distorted_original_range : Tensor of size (width, height, 3) of type tf.float.
Image Tensor with distorted color in [0,255] intensity range
"""
# Make the range to be in [0,1]
img_float_zero_one_range = tf.to_float(image_tensor) / 255
# Randomly distort the color of image. There are 4 ways to do it.
