Abstract
A system and method for generating and using a correlation filter. The method includes providing a plurality of training images, each training image being paired with an associated target correlation plane. Each training image and target correlation plane pair is processed. A final filter is generated, wherein the final filter is useable to generate a filtered output correlation plane of each training image. The final filter is selected to collectively minimize errors between the filtered output correlation plane of each training image and its associated target correlation plane. The final filter can be used in a wide variety of still image and video based object location and tracking applications.

A method of generating a correlation filter with respect to a target object, the method comprising:
- providing a plurality of training images, each training image being paired with an associated target correlation plane that reflects relative locations of images of the target object within the training image;
- processing each training image and target correlation plane pair and generating a final filter that is useable to generate a filtered output correlation plane of each training image, the final filter being selected to collectively minimize errors between the filtered output correlation plane of each training image and its associated target correlation plane.
A system for generating a correlation filter with respect to a target object, the system comprising:
- an input configured for receiving a plurality of training images, each training image being paired with an associated target correlation plane that reflects relative locations of images of the target object within the training image;
- a processor configured to process each training image and target correlation plane pair and generate a final filter that is useable to generate a filtered output correlation plane of each training image, the final filter being selected to collectively minimize errors between the filtered output correlation plane of each training image and its associated target correlation plane.
A non-transient computer-usable medium having computer readable instructions stored thereon for execution by a processor to perform a method comprising:
- providing a plurality of training images, each training image being paired with an associated target correlation plane that reflects relative locations of images of the target object within the training image;
- processing each training image and target correlation plane pair and generating a final filter that is useable to generate a filtered output correlation plane of each training image, the final filter being selected to collectively minimize errors between the filtered output correlation plane of each training image and its associated target correlation plane.
