Object detection

A computer system for object detection, the computer system comprising:

• one or more processors;
• one or more computer-readable memories coupled to at least one of the one or more processors;
• a set of computer program instructions stored in the memory and executed by at least one of the one or more processors in order to perform actions of:
• receiving a user input that specifies a plurality of first regions and one or more second regions in a template image, wherein the one or more second regions include one or more objects of interest;
• for each of the plurality of first regions, finding a third region in an image under detection corresponding to one of the plurality of first regions in the template image by matching the image under detection with the template image;
• computing a transformation function based on the matching from each of the plurality of first regions to its corresponding third region and a distance between two or more pairs of first regions;
• and
• applying the computed transformation function to the one or more second regions to localize one or more fourth regions in the image under detection for the object detection.

A computer program product for object detection, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the program instructions being executable by a device to cause the device to perform a method comprising:

• receiving a user input that specifies a plurality of first regions and one or more second regions in a template image, wherein the one or more second regions include one or more objects of interest;
• for each of the plurality of first regions, finding a third region in an image under detection corresponding to one of the plurality of first regions in the template image by matching the image under detection with the template image;
• computing a transformation function based on the matching from each of the plurality of first regions to its corresponding third region and a distance between two or more pairs of first regions;
• and
• applying the computed transformation function to the one or more second regions to localize one or more fourth regions in the image under detection for the object detection.
