Abstract

We study the problem of estimating the edges in noisy images by linewise procedures. We show that the straight forward estimation method (naïve Iinewise procedure) does not attain the asymptotically minimax rate of accuracy as the number of observations tends to [ infinity ]. We propose the modified linewise procedure which has the asymptotically minimax rate.
