Image Enhancement Using Self-Examples and External Examples

摘要

Systems and methods are provided for image enhancement using self-examples in combination with external examples. In one embodiment, an image manipulation application receives an input image patch of an input image. The image manipulation application determines a first weight for an enhancement operation using self-examples and a second weight for an enhancement operation using external examples. The image manipulation application generates a first interim output image patch by applying the enhancement operation using self-examples to the input image patch and a second interim output image patch by applying the enhancement operation using external examples to the input image patch. The image manipulation application generates an output image patch by combining the first and second interim output image patches as modified using the first and second weights.

1. A method comprising:
receiving an input image patch of an input image; determining a first weight for a first enhancement operation using self-examples and a second weight for a second enhancement operation using external examples; generating a first interim output image patch by applying the first enhancement operation to the input image patch and a second interim output image patch by applying the second enhancement operation to the input image patch; and generating an output image patch by combining the first interim output image patch modified using the first weight and the second interim output image patch modified using the second weight.
