Compute the size of pixel

python compute_area.py --input {image directory} --meta {location of meta data (or save directory)}

meta data is maintained in json file.
Image file name should consist of {name of camera}-{numbering}
By default, separator is -, but you can change it in SEPARATOR

Current version supports only if there are circles of the same size in images.

Hough transformation algorithm searches for known size of circles. ACTUAL_DIM (diameter of circle, unit: cm)

In case no appropriate representative circles, the image is skipped.
