May i know how to draw the rectangle at the object when the object is largest than the minimum size(left window picture), i already got to draw the rectangle when it was largest than the minimum size(right window picture) but i confused about this "Original Image" window(left window picture)

This is My Picture

ok now at "original image" window (right picture), it will only draw rectangles on 2 largest object(black color) was been detect. now i need add some function that is it will draw rectangle on object if only the object was largest than the minimum size (eg, 100*300)

if (minRect.area() > desiredValue) {rectangle( frame, minRect, Scalar( 0, 0, 255 ),2 );}

if (minRect.width() > desiredWidth && minRect.height() > desiredHeight) {rectangle( frame, minRect, Scalar( 0, 0, 255 ),2 );}

if (minRect.width() > 100 && minRect.height() > 150) {rectangle( frame, minRect, Scalar( 0, 0, 255 ),2 );}

it got error there :expression preceding parentheses of apparent call must have (point-to-) function type

Yeah, never mind the ().

if (minRect.width > 100 && minRect.height > 150) {rectangle( frame, minRect, Scalar( 0, 0, 255 ),2 );}
