+function [ overlapRatio ] = bboxOverlapRatio(bboxA, bboxB, ratioType)
+// Compute the overlap ratio between the bounding boxes A and B.
+//
+// Calling Sequence
+// [ overlapRatio ] = bboxOverlapRatio(bboxA, bboxB);
+// [ overlapRatio ] = bboxOverlapRatio(bboxA, bboxB, ratioType);
+//
+// Parameters
+// bboxA: Bounding box A of the form [x, y, width, height];
+// bboxB: Boundng box B of the form [x, y, width, height];
+// ratioType (Optional Argument): Method to be used to compute the ratio. Set this to either 'Union' or 'Min'. Default computation method is set to 'Union'.
+// overlapRatio: Overlap ratio between the bounding boxes A and B.
+//
+// Description
+// Compute the overlap ratio between the bounding boxes A and B.
+//
+// Examples
+// bboxA = [1 2 3 4];
+// bboxB = bboxA + 100;
+// overlapRatioMin = bboxOverlapRatio(bboxA, bboxB, 'Min');
+// overlapRatioUnion = bboxOverlapRatio(bboxA, bboxB);
