tf.image.adjust_brightness( image, delta )
See the guide: Images > Image Adjustments
Adjust the brightness of RGB or Grayscale images.
This is a convenience method that converts an RGB image to float representation, adjusts its brightness, and then converts it back to the original data type. If several adjustments are chained it is advisable to minimize the number of redundant conversions.
delta is added to all components of the tensor
delta are converted to
float before adding (and
image is scaled appropriately if it is in fixed-point representation). For regular images,
delta should be in the range
[0,1), as it is added to the image in floating point representation, where pixel values are in the
image: A tensor.
delta: A scalar. Amount to add to the pixel values.
