To create an image processing program for counting number of grains in images and for listing XY coordinate positions of them.

Explanation on grain images

Grain varieties: polished rice, husked rice, red bean (Azuki), and soybean

    Images were acquired by using white LED and a CCD color camera (VGA). Please pay attention below two points when creating algorithm:

1. To exactly count number of overlapped grains, too

   Some grains were overlapped, but human can count all the grain numbers on image.It is important to create an algorithm for handling the overlapped grains.

   
   

   To create algorithm to count four varieties of grains in one program

   Although images of four different variety grains were assigned, single variety of grain is in an image. Make a program to count grain numbers of all four types of grains.

    Four sample images of the four variety grains are below. First, make a program to count these grains by use of the images and send it to Tomoo Shiig, a contact person of this contest by e-mail. Competition will be conducted by use of the four images and additional unknown 16 images (these images are opened at the study meeting).
    That means that created programs are supposed to execute for 20 images.
