I am trying to segment out human by removing noise and shadow from the image shown below:

Here are the steps:

1. 
   

   I first threshold the image to contain only pixels with intensity value equal to 255

   
   


2. 
   

   Erode the image

   
   


3. 
   

   Dilate the image

   
   


4. 
   

   Perform closing

   
   

and got the the following result:

Can anyone suggest what more should I do to improve the result? As there is some noise that is not removed and the human is not segmented correctly. Any help is much appreciated.
