Algorithm 3 Generation of Individual Image Features Using Custom Method

procedure GenerateManualFeatures (file)     Read image I from $file$     Adjust I and convert to binary images $bw$     Label connected components in $bw$ to L     Extract properties of regions in L into s     Find the largest region in s as $circle$     Extract edge coordinates x, y from $circle$     Calculate inscribed circle properties: R, $cx$, $cy$     Calculate convex hull points x, y of $circle$     Calculate circumscribed circle properties: $center$, $radius$     Compute features: R, $radius$, $radius-R$, $s\left(numer\right).Area$, etc.     return computed features as ManualFeatures end procedure
