In this paper we propose a novel technique for wavelet-based multi-resolution corner detection. The method is based on the search of the zero crossings of the laplacian at different scales along the line that describes the trajectory of the maxima as the scale varies. The proposed techniques allows us to achieve sub-pixel accuracy and provides us with useful scale information on the detected features.

Abstract
In this paper we propose a novel technique for wavelet-based multi-resolution corner detection. The method is based on the search of the zero crossings of the laplacian at different scales along the line that describes the trajectory of the maxima as the scale varies. The proposed techniques allows us to achieve sub-pixel accuracy and provides us with useful scale information on the detected features.
