tensorflow::ops::AdjustContrast

#include <image_ops.h>

Adjust the contrast of one or more images.

Summary

images is a tensor of at least 3 dimensions. The last 3 dimensions are interpreted as [height, width, channels]. The other dimensions only represent a collection of images, such as [batch, height, width, channels].

Contrast is adjusted independently for each channel of each image.

For each channel, the Op first computes the mean of the image pixels in the channel and then adjusts each component of each pixel to (x - mean) * contrast_factor + mean.

Arguments:

  • scope: A Scope object
  • images: Images to adjust. At least 3-D.
  • contrast_factor: A float multiplier for adjusting contrast.

Returns:

  • Output: The contrast-adjusted image or images.
