Sat1=regionprops(MaskIm, {'Area', 'Eccentricity', 'EulerNumber', 'MajorAxisLength', 'MinorAxisLength', 'Orientation', 'Perimeter'});

How to divide MajorAxisLength with MinorAxisLength and then add it to Sat1 structure under 'AspectRatio' name?

MaskIm = imread('text.png');
Sat1=regionprops(MaskIm, {'Area', 'Eccentricity', 'EulerNumber', 'MajorAxisLength', 'MinorAxisLength', 'Orientation', 'Perimeter'});
AR = [Sat1.MajorAxisLength]./[Sat1.MinorAxisLength] ;
[Sat1.AspectRatio] = deal(AR) ;

Thank you. This is working but then I am not able to filter the region using 'bwpropfilt' anymore.

%
  % AR =( [MaskIminFinal_log_properties.MajorAxisLength]./[MaskIminFinal_log_properties.MinorAxisLength])' ;
for i = 1:length(AR)
  MaskIminFinal_log_properties(i).AspectRatio = AR(i) ;
end
 MaskIminFinal_log_New = bwpropfilt(MaskIminFinal_log, 'AspectRatio', [1, 3]);
