This paper deals with the study of dependence of subpixel accuracy of edge detection in 1-D images on number of used samples. Our study includes four methods for edge detection with sub-pixel accuracy in 1-D images: method based on approximation of real image function with erf function, moment-based edge operator, technique using spatial moments of the image function and the method based on wavelet...
This work addresses the problem of automatic wire recognition in images obtained from an unmanned aerial vehicle (UAV). As wires are thin structures it is difficult to extract particular pixels eliminating background. We propose the method that allows detecting wires and estimating their parameters without any human intervention.
