The method commonly employed to identify corresponding points between overlapping images in image stitching is Feature Detection and Matching.

Here's a step-by-step explanation:

1. Feature Detection: This is the first step where you identify interesting parts or 'features' of an image. These features are regions in the image that stand out and can be easily tracked and compared. They could be corners, edges, or objects. There are many algorithms to perform feature detection, such as SIFT (Scale-Invariant Feature Transform), SURF (Speeded Up Robust Features), FAST (Features from Accelerated Segment Test), etc.

2. Feature Description: Once the features are detected, they need to be described in a way that they can be easily compared. This is done by creating a 'descriptor' for each feature. A descriptor is a representation of the feature that captures its main characteristics. Again, there are many algorithms to create descriptors, such as SIFT descriptors, SURF descriptors, ORB (Oriented FAST and Rotated BRIEF), etc.

3. Feature Matching: The final step is to match the features from different images. This is done by comparing the descriptors of features from the first image with descriptors of features from the second image. The features with the most similar descriptors are considered a match. There are different algorithms to perform this matching, such as Brute-Force matcher, FLANN (Fast Library for Approximate Nearest Neighbors) based matcher, etc.

So, in the context of image stitching, you would detect and describe features in all the images. Then, you would match features between each pair of images that have some overlap. These matched features will give you corresponding points between the images, which can be used to align and stitch the images together.
