Patch Partitions and Image Processing

In a digital medium environment for digital image processing, a computing device comprising:

• at least one processor;
• and
• one or more computer-readable storage media having instructions stored thereon that, responsive to execution by the at least one processor, causes the at least one processor to implement functionality including:
• obtaining a plurality of example training samples taken from example images, each example training sample having a plurality of example patches;
• grouping the example patches into respective ones of a plurality of partitions, the example image patches in a partition being similar one to another;
• calculating an image processing operator for each of the partitions based on the example image patches in the respective partition;
• determining distances between the plurality of partitions that describe image similarity of patches of the plurality of partitions, one to another;
• and
• configuring a storage to provide the determined distance and the image processing operator to process an image in response to identification of a respective said partition that corresponds to a patch taken from an image external to the storage.

At least one computing device in a digital medium environment for digital image classification and adjustment, the at least one computing device including a processing system and at least one computer-readable storage medium, the at least one computing device comprising:

• means for obtaining a plurality of example training samples taken from example images, each example training sample having a plurality of example patches;
• means for grouping the example patches into respective ones of a plurality of partitions, the example image patches in a partition being similar one to another;
• means for calculating an image processing operator for each of the partitions based on the example image patches in the respective partition;
• means for determining distances between the plurality of partitions that describe image similarity of patches of the plurality of partitions, one to another;
• and
• means for configuring a storage to provide the determined distance and the image processing operator to process an image in response to identification of a respective said partition that corresponds to a patch taken from an image external to the storage.
