In a binary image I have two objects , from which I wanted to detect just one object and neglect the others. Is there any sutomated detection to find object other tham selecting ROI by roipoly, imfreehand, roicolor etc???

There are lots of ways to define an ROI. Take a look at my BlobsDemo Image Segmentation Tutorial where I define the foreground ROI on the basis of intensity. You can also do it based on color, different from a prior frame of video, etc. etc.
If you want me to post my demo where you can extract the N largest or smallest blobs, let me know.

I'm not sure what you mean. I do do that. I gave the link and in the code it shows, with comments, how the blobs are extracted by thresholding and labeling. If there is something more helpful that I can do, then let me know, but be more specific.
