Particle statistics with calibration
From Intelligent Perception
The task for Pixcavator: "What I need it for the software to analyse the attached image in order to get an area for each particle. I compare the area with a standard 2mm square that is included in the image. I then take the values and create a histogram showing the size distribution of the particles."
I analyzed the image with these settings: 20, 10, 0, 69, 0, 255. The image is below.
211 pixels = 2 mm * 2 mm = 4 sq mm and 1 pixel = 4 / 211 sq mm = .019 sq mm.
