Fill the regions with imfill(). Then call bwareafilt(bw, 1) to extract the largest blob. Erode if a bit to get inside the outer rectangular edge, and use it as a mask on the initial binary image.

Use imerode.

From Matlab documentation:

IM2 = imerode(IM,SE) erodes the grayscale, binary, or packed binary image IM, returning the eroded image IM2. The argument SE is a structuring element object or array of structuring element objects returned by the strel function.

Example:

Erode a binary image with a disk structuring element.

originalBW = imread('circles.png');  
se = strel('disk',11);        
erodedBW = imerode(originalBW,se);
imshow(originalBW), figure, imshow(erodedBW)
