You should use the NI Vision Assistant to experiment with the numbers. You can see the results of the changes immediately on the screen. If you've installed the NI FRC tools on your computer, you should have it.
Start it up, choose "Acquire Image", choose "Axis Camera", fill in the IP info, and click the play button and you'll see your camera feed. If you click the single play button it will take a snapshot. Then click the last icon to "store the acquired image in browser". Then go to the Process Images page, choose the Color Threshold tool, select HSV, and then you can tweak the numbers there and see exactly what it would do to your image.
You can, of course, add multiple processing filters along with the final particle report - exactly the same as you would in your program.
Keep in mind that in Java you don't have access to all the different tools that are shown in the Vision Assistant.
