IMAGE PROCESSING

摘要

An image-processing method includes obtaining an image including a target object, the image being formed by an array of pixels. A current frame portion is extracted from the image, the frame portion being at least a portion of the pixels forming the image, corresponding to a region of interest in the image, the region of interest comprising the target object. A previously calculated current super-resolved frame portion is provided, corresponding to the region of interest in the image. An updated super-resolved frame portion is calculated from the current frame portion and the current super-resolved frame portion.

1. An image-processing method comprising the steps of:
(i) obtaining an image including a target object, the image being formed by an array of pixels; (ii) extracting a current frame portion from the image, the frame portion being at least a portion of the pixels forming the image, corresponding to a region of interest in the image, the region of interest comprising the target object; (iii) providing a previously calculated current super-resolved frame portion, corresponding to the region of interest in the image; and (iv) calculating an updated super-resolved frame portion from the current frame portion and the current super-resolved frame portion, both being weighted with respective weightings in the calculation, and (v) repeating for a plurality of times steps (i) to (iv) of the method for successive images, wherein the respective weightings used in the calculation of each of the successive updated super-resolved frame portions are such that the effective contribution made to the super-resolved frame portion by a given frame portion progressively decays with each successive calculated super-resolved frame portion.
