Abstract Pattern Matching Techniques
Abstract pattern matching involves stepping back from the image itself and working at a higher level, grouping features in an abstract way to infer the presence of objects. Graph matching has long been a conventional method for performing this task, but in the right circumstances a suitable adaptation of the generalized Hough transform can actually outperform it. This chapter discusses inference procedures and considers relational descriptions of scenes and the various types of searches that can be used with image data.
Look out for:
• the match graph approach for identifying objects from their point features.
• how the need for robustness against noise, clutter, and occlusion translates into the requirement ...
