Spotter is an open source tool that can be used to count a wide variety of objects within images, provided that the objects are relatively circular. The interface is easy to use, yet highly adjustable. Simply adjust the six parameters as needed, choose your output options, and select the image(s) you want to count! Spotter will automatically save the image name with the parameters used, the number of circles found, and the minimum, maximum, and average areas of the circles found in a new CSV, which will be appended to with future runs. You also have the option to display and/or save the output image, so you can see which objects are being counted.
Spotter has a number of features that make it convenient to use. Once you find a set of parameters that works well for your objects, you can save them in a config file to use later, and you can run an entire directory of images all at once to cut down on active time. If you ever get confused, just consult the help tab.
Spotter is currently available for Windows 7 and above.
