Computer Vision Practical implementation

1) Path

    A path from pixel p with coordinates (x, y) to pixel q with coordinates (s, t) is a sequence of distinct pixels with coordinates:
          (x0, y0), (x1, y1), (x2, y2) … (xn, yn),where (x0, y0)=(x, y) and (xn, yn)=(s, t);
          (xi, yi) is adjacent to (xi-1, yi-1)

Airport Distance Using Path

    - Calculate the distance between indian airports by using path 
    - Path calculated using Euclidean distance
    - Assuming 4,d and 8 connected
