Drawing circles on Images of wood logs

Job is to use our custom software to draw circles at the end of each Wood log. Examples will be given on how to do it. Pictures will be provided. Amount of pictures is very large so this could be a long-term project. To apply for the job a test assignment will be required to be finished. If you wish to apply for the test assignment you need to have a computer with Java and Dropbox installed. Please send me your dropbox e-mail and I will share the test assignment paper and the folder where you can do the work. You'll get paid based on how many images /logs you completed. The bigger the team better.
