Are the images with the blue background your starting images?

Ps. Well written question with sample images provided. +1!

If you have the Image Processing Toolbox, have a look at using morphology operations to simplify the binary image into one blob. The 'close' option of bwmorph might be a good starting point.

Then to get the measurement, try the 'Perimeter' and 'Area' options of regionprops.

so far i managed to get to this point how do i now calculate the perimter of this hand . ive got the left image using bmarea and the one on the left is when the image is closed. http://www.flickr.com/photos/60171113@N05/5602943214/ thank u

Prashan, it's better to comment on my answer rather than give extra answers. Anyway, your image looks good - you should be able to get the perimeter easily using regionprops, with 'Perimeter' as the required property.
