Our portrait form needs a basic consistency check before we discuss its face shape categories. I want to distinguish a different crop from an actual change in the visible facial outline. My starting set would contain one portrait used with permission and a note of its original size. Each copy would retain the same facial pixels while adding or removing empty space around them. I am considering <a href=https://faceshapecalculator.top>face shape detector</a> as a reference while drafting the questions. I have not run these comparisons yet, so I cannot claim that any label stays consistent. A useful record would include the crop, the returned category and any stated uncertainty. Would you compare only the final categories, or also record where the outline was detected? The acceptance rule should acknowledge ambiguity while still making unexplained changes easy to investigate.
