Method and apparatus for tracking an object
First Claim
Patent Images
1. A method of tracking an object comprising the steps of:
- (i) obtaining from a first imager a plurality of images of a target object;
(ii) calculating by an image processor a super-resolved image of the target object from the plurality of images;
(iii) obtaining from a second imager a further image of the target object, the plurality of images and the further image being obtained at the same viewing angle or at viewing angles of negligible difference;
(iv) de-resolving the super resolved image; and
(v) correlating by the image processor the further image with the de-resolved image, in order to identify the location of the target object in the further image, whereby the, higher quality, super-resolved image may thus be used in order to better identify the location of the target object in the, lower quality, further image.

Abstract
In a method of tracking an object, a plurality of images of a target object is obtained. A super-resolved image of the target object is calculated from the plurality of images. A further image of the target object is obtained. The further image is correlated with the super-resolved image, in order to identify the location of the target object in the further image.

11. An image-processing apparatus comprising:
- (i) an imager for obtaining a plurality of images and a further image, each including a target object and being formed by an array of pixels; and
(ii) an image processor configured to;
a. calculate a, higher quality, super-resolved image of the target object from a plurality of images;
b. de-resolve the super resolved image; and
c. correlate the, lower quality, further image with the, higher quality, de-resolved image, in order to identify the location of the target object in the further image. - View Dependent Claims (12, 13)

14. A computer program product embodied on non-transitory computer-readable medium, the product being configured to cause, when the computer program is executed, data-processing apparatus to:
- (i) receive a plurality of images of a target object;
(ii) calculate a, higher quality, super-resolved image of the target object from the plurality of images;
(iii) obtain a further image of the target object, the plurality of images and the further image being obtained at the same viewing angle or at viewing angles of negligible difference;
(iv) de-resolve the super resolved image; and
(v) correlate the, lower quality, further image with the, higher quality, de-resolved image, in order to identify the location of the target object in the further image.
- (i) receive a plurality of images of a target object;
