Description
  • Air pollution is a global problem all over the world. Bioindicator approach is a modern and progressive way how to determinate an amount of damage caused by pollution in nature. We have gained electron-microscope pictures of pores of needles from Norway spruce. These needles have miscellaneous structure of epidermis when the air is clean. If the tree grows in polluted air, the needles start to cover by epicuticular waxes to protect themselves and their epidermis became coherent. Coherence can indicate an amount of air pollution and it is possible to resolve it into five classes by damage. In our work, we have decided to exploit this effect and tried to divide pictures into classes by means mathematic detection of edges. We used Prewitt, Sobel, Robinson, Kirsch and Canny methods and compared them in use for resolving pictures to pollution classes without human senses, only according a sum of detected edges.
