I got some dimensions in pixels from the image below (for example TotalArea=520000 pixels). I need to convert my dimensions from pixel to millimeters. I'm a newbie in matlab and I don't know where to start with this. I've already made the calibration with the Camera Calibrator provided by Matlab and I've obtained two folders:
- CameraParameters
- EstimationError
The image is the following:

You need to know the length in millimeters of a particular object or feature in the image to make that conversion.

@DGM right. I mentioned shadows and background flattening to him in his other question but he just said I was criticizing his question and he didn't want any more help from me. Too bad. With my 45 years experience designing imaging systems and image analysis software I could have been helpful.
