Refined Edge Features

Edges extracted with five different sets of operator parameters, including the three shown on a separate page, were or'ed together to form the two images in the top row.  After operation including dilation/erosion, thinning and de-branching, refined edge features as shown in the bottom row were obtained.  Small pieces of features from each individual set of parameters were merge into longer and more characteristic feature, which will make the next step of feature matching easier and more reliable.
