Description

The following script generate error:
------------------------------------
Mat kernel = getStructuringElement(MORPH_RECT, Size(1, 3));
dilate(input_img, result_img, kernel);
------------------------------------

In my environment (VC++2010), the error message is assertion error in vector:
"Expression: vector subscript out of range"

on the other hand, the following script is ok:
----------------------------------------------------
Mat kernel = getStructuringElement(MORPH_RECT, Size(3, 1));
dilate(input_img, result_img, kernel);
----------------------------------------------------

erode() and morphologyEx() also have same symptom.
