Abstract

Image correspondence is established by “matching” the feature descriptors of the interest points in the target image to that of the reference image. By acceptance testing, we refer to a postmatching hypothesis test used to screen out potential false matches—conventionally using descriptor test statistics. We propose a new acceptance testing strategy that does not rely on the descriptor test statistics exclusively. The contribution we bring is to demonstrate that, unlike feature matching, acceptance testing may incorporate additional photometric values of the scene to improve the recall rate. We show experimentally that the acceptance testing strategy that incorporates image feature detection statistics we refer to as detector response-ratio thresholding that are usually excluded from the feature descriptor vectors has a superior recall–precision performance compared to the state-of-the-art feature extraction techniques.
