How to calculate the projected area and the contour of a particle?

Area, in this instance, refers to the projected area of a particle. The projected area of a particle can be calculated by multiplying the number of pixels by the area of a pixel. The area of a pixel can be calculated with the help of the calibration coefficient.

The perimeter of a particle projection refers to the total length of its projected contour. The perimeter can be calculated through contour representation using curve fitting with the help of an algorithm.
