Need help in creating an algorithm
Posted:

Hello,
Moderators, I posted on another discussion, but it had no activity in it since March, so I'm RePosting here.
I am a software engineer that is working on an application that performs image and shape diagnostics. I need to find an algorithm that recalibrates feret dimensions. The system scans on a single pixel line. The software calibrates based on crossdirection (X) and MachineDirection (Y). We try to make the calibration of both axis the same, but due to hardware restrictions we sometimes need drastically different calibration factors between CrossDirection and MachineDirection. Before calibration we are given a calculation based on the number of pixels in the shape.
Given the Max Feret Diameter, it's orientation Angle from cross direction, and the min Feret Diameter, can you recalibrate all three values on different calibration factors, as an example, CrossDirection Calibration Factor=0.0016143, MachineDirection Calibration Factor=0.0044442
Please show your work so I can understand how it works
