Intelligent Scissors
              The  Intelligent  Scissors  tool  shares  certain  characteristics  with  the  Lasso,  some  with  the  Path  tool,  and  some
              characteristics  exclusively  with  it.  When  attempting  to  identify  a  zone  with  prominent  colour  changes  near  the
              boundaries, it can be helpful. To utilise the Scissors, click the boundaries of the zone you want to pick in order to
              establish a collection of “control nodes,” also known as anchors or control points. Following any high-contrast edges it
              can locate, the tool creates a continuous curve that passes through these control nodes.
              Step 1:   Click on Tools   Selection Tools   Intelligent Scissors.
              Step 2:   Point and click at various points around the edge of the input image. As the anchor points are marked on the
                       edges with this point and click technique, the tool automatically draws the selection line around the edges
                       that it detects.
              Step 3:  Press Enter key outside the boundary.
              Step 4:  The selection marquee is created.
