The inverse filter does a terrible job due to the fact that it divides in the frequency domain by numbers that are very small, which amplifies any observation noise in the image. BW = edge(I) takes a grayscale or a binary image I as its input, and returns a binary image BW of the same size as I, with 1's where the function finds edges in I and 0's elsewhere. For more information, see Code Generation for Image Processing. Unfortunately, conv2 can only handle filtering near the image boundaries by zero-padding, which means that filtering results are usually inappropriate for pixels close to the boundary.
