A new edge detection algorithm for a binary image based on filter back projection
Yi Wang · Journal of Beijing University of Chemical Technology · 2008
Using the so called cup effectappearing in CT-image-reconstruction based on filter back projection,a new method of edge detection has been obtained by adjusting the result of image normalization with a given threshold factor to the minimum minus values of the reconstructed CT-values.Furthermore,through an improved distance rule,the optimum threshold value which gives the best edge detection in the different images,is presented.
