Harris corner detection based on the multi-scale topological feature

In order to increase the property of the corner detection, an improved method of harris corner detection based on the multi-scale topological was proposed. This method extracts the angular points on the basis of the topological structure, through which not only narrows the range of the harris corner detection but also reduces the influence of the multi-scales factor. The experiments show that the harris corner detection based on the topological structure is better than the original algorithm with certain scale invariance and noise depression capability.
