Abstract [en]

This report evaluates the stability of two image interest point detectors, star-pattern points and points based on the fourth order tensor. The Harris operator is also included for comparison. Different image transformations are applied and the repeatability of points between a reference image and each of the transformed images are computed. The transforms are plane rotation, change in scale, change in view, and change in lightning conditions. We conclude that the result largely depends on the image content. The star-pattern points and the fourth order tensor models the image as locally straight lines, while the Harris operator is based on simple/non-simple signals. The two methods evaluated here perform equally well or better than the Harris operator if the model is valid, and perform worse otherwise.
