tf.image.adjust_jpeg_quality(
    image, jpeg_quality, name=None
)

This is a convenience method that converts an image to uint8 representation, encodes it to jpeg with jpeg_quality, decodes it, and then converts back to the original data type.

jpeg_quality must be in the interval [0, 100].

Args:

image: 3D image. Size of the last dimension must be None, 1 or 3.
jpeg_quality: Python int or Tensor of type int32. jpeg encoding quality.
name: A name for this operation (optional).

Returns:

Adjusted image, same shape and DType as image.

Usage Example:

>> import tensorflow as tf
>> x = tf.random.normal(shape=(256, 256, 3))
>> tf.image.adjust_jpeg_quality(x, 75)

Raises:

InvalidArgumentError: quality must be in [0,100]
InvalidArgumentError: image must have 1 or 3 channels
