SYSTEM AND METHOD FOR EFFICIENT FEATURE DIMENSIONALITY AND ORIENTATION ESTIMATION |
摘要 |
A method of automatically detecting features in an image includes: designing a gradient detection filter and a line detection filter; applying the gradient detection filter and line detection filter to detect structures in an image; and estimating feature dimensionality and orientation of the detected structures in the image. The computation cost of gradient detection and line detection when applied on an image is a constant number of operations independent of the size of the gradient and line detection filters.
