+function [out]=insertObjectAnnotation(input_image,object)
+// Detect human body parts like face ,nose,eye and ear.
+//
+// Calling Sequence
+// output_image = insertObjectAnnotation(input_image,object);
+//
+// Parameters
+//
+// input_image : image matrix on which Cascadeobject detection has to be performed
+// object : An input string which specify the name of the object which has to be detect
+// output_image : an output image in which object are bounded by rectangle.
+//
+// Description 
+// This function uses the Viola-Jones algorithm to detect the object from given input image.The function first finds the target object on the image then makes a  rectangle on detected part of the image.To detect the object it uses already trained data  which are stored in .xml file.User can use own trained data for better object detection.
+//
+// Examples 
+// a = imread('lena.jpeg');
+// b = insertObjectAnnotation(a,'face');
+// imshow(b)
+//
+// Authors.
