my code is
I=imread(image);
img=rgb2gray(I);
[col, row] = find(img<250);
imout = I(min(col):max(col), min(row):max(row));
imshow(imout);
[rows columns numberOfBands]=size(imout);
blockSizeR = 16;
blockSizeC = 16;
wholeBlockRows = floor(rows / blockSizeR);
wholeBlockCols = floor(columns / blockSizeC);
blockNumber=1;
for row = 1 : blockSizeR : rows
for col = 1 : blockSizeC : columns
row1 = row;
row2 = row1 + blockSizeR - 1;
row2 = min(rows, row2);
col1 = col;
col2 = col1 + blockSizeC - 1;
col2 = min(columns, col2);
block=imout(row1:row2, col1:col2);
subplot(16,16,blockNumber);
imshow(block);
blockNumber = blockNumber + 1;
end
end

Vidya - consider using the videowriter to write each of your block images to file. See the examples in the provided link to get an idea on what you can try.
