HI

I am identifying objects on a pice of (10cm x 9cm) photographed graph paper to quantify the degree of distortion of the camera set up we are using.

Using “identifyPrimaryObjects”. I can easily identify 100s of what look like squares. However I would like to be able to determine how perfect the squares are (90° angles at the corners) versus being somewhat rhombus / parallelogram.

**From “MeasureObjectSizeShape” or another module can you suggest what measurement might most easily capture this?**

I have tried to using “MeasureObjectSizeShape” and “calculateMath” to generate the ratio of AreaShape_MaxFeretDiameter to AreaShape_MinFeretDiameter. However, while the squares really do look visually like squares I do not get a ratio of 1 (which is what I think a square should have). I get 1.3-1.4.

If anybody had better ideas I would love to try them.

Thanks

Guy
