1. A method for merging a first candidate area relating to a candidate feature in a first image and a second candidate area relating to a candidate feature in a second image, wherein the first image and the second image have an overlapping region, and wherein at least a portion of the first candidate area and at least a portion of the second candidate area are located in the overlapping region, the method comprising:
determining an image overlap size indicating a size of the overlapping region of the first image and the second image;
determining a candidate area overlap ratio indicating a ratio of overlap between the first candidate area and the second candidate area;
determining a merging threshold based on the image overlap size; and
on condition that the candidate area overlap ratio is larger than the merging threshold, merging the first candidate area and the second candidate area, thereby forming a merged candidate area.
