Backgrounds (1)
• A Field Server is a Web server that has a weather station and a camera.
• Field Server has been installed in many fields all over the world.
• A standard Field Server takes an image every 2 minutes.
• A total of 720 images for each Field Server are stored every day.

Backgrounds (2)
• Existing application• Image viewer shows images as
thumbnail or animation.(Web application & Java Applet)
• More effective use of images is expected.• observing the growth of plants• detecting the changes in a field

Features of Image
• Intermittent image.• Changes do not occur fundamentally between
the images taken in the field.• Users want to see only the images in which
change took.– appearance / disappearance of people or cars– density change by daylight– shaking of a tree by wind– clouds flowing past
These unimportant changes should not be detected.

The image with appearance of this day is only this one.

Server
1. Download images from the image server to the image change detection server.
2. Execute the image change detection program, and calculate the value of change between images.
3. Transform the change information into XML format and output it to a file.

Conclusions / Future Works
• Expected role of this system • To appeal the safety of agricultural products by
extracting images of agricultural work and show them to a consumer
• To monitor the theft of agricultural products and illegal disposal of garbage.
• To raise the accuracy of the image change detection• Setting up the threshold for an image change and
optimizing the program parameters based on the installation location of a Field Server.
