Comparison of relevant portions of images

A computer program product for enforcing land use controls, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a computer to perform a method comprising:

• providing in a computing system a reference image and a current image representing a territory at different times;
• determining, by the computing system, a partition of the reference image into a first relevant portion and a first non-relevant portion and of the current image into a second relevant portion and a second non-relevant portion according to a partitioning rule;
• comparing, by the computing system, the second relevant portion of the current image with the first relevant portion of the reference image for determining one or more different regions of the current image with respect to the reference image;
• determining, by the computing system, one or more critical regions of the current image corresponding to the one or more different regions according to a criticality rule;
• and
• providing, by the computing system, a notification based on the one or more critical regions for use in enforcing land use controls.

A system for enforcing land use controls, the system comprising:

• one or more processors;
• and
• a memory communicatively coupled to the one or more processors,
• wherein the memory comprises instructions which, when executed by the one or more processors, cause the one or more processors to perform a method comprising:
• providing in a computing system a reference image and a current image representing a territory at different times;
• determining, by the computing system, a partition of the reference image into a first relevant portion and a first non-relevant portion and of the current image into a second relevant portion and a second non-relevant portion according to a partitioning rule;
• comparing, by the computing system, the second relevant portion of the current image with the first relevant portion of the reference image for determining one or more different regions of the current image with respect to the reference image;
• determining, by the computing system, one or more critical regions of the current image corresponding to the one or more different regions according to a criticality rule;
• and
• providing, by the computing system, a notification based on the one or more critical regions for use in enforcing land use controls.
