Abstract
A method for identifying corresponding image regions in a sequence of images (1; 21) is provided, wherein one or more features (P2a, P2b) from a second image are assigned to each feature (P1a, P2a) from a first image using correspondence graphs. The costs (C1-C5) that are associated with each assignment are represented by functions. The concrete selection of a unique correspondence for each feature which is then used for the further calculations is performed on the basis of these costs.
Claims8
A method for identifying corresponding image regions in a sequence of images (1;
- 21), comprising:
- in the images (1;
- 21), for each said image detecting a multiplicity of features (6, 7) by computer image processing using a computer and for each said image, extracting descriptors relating to the features (6, 7) using the computer image processing, recognizing a first features M1A (8) of the features from a first one of the images (1) of the sequence of images and a second features M2A (28) of the features from a second one of the images (21) of the sequence of images as being in correspondence with one another in terms of content if at least the descriptors associated with first and second ones of the features are similar to one another in accordance with a defined rule, so that a first image region of the first image (1) with the first feature M1A (8) is recognized as being in correspondence in terms of content with a second image region of the second image (21) with the second feature M1B (28), and for recognition of a content correspondence, additionally checking whether at least one first further feature M2A (9), which neighbours the first feature M1A (8) in the first image (1), is similar in accordance with a specified rule to a second further feature M2B (29), which neighbours the second feature M1B (28) in the second image (21).
