MATLAB does not have function to convert binary image to gary level image.

What format is it in? PNG? dicom? Attach the image here, not on some other third party web site. If it's some proprietary format you'll have to use a special reader for it. Type

>> imformats

to see what imread() can handle.

To read the image into an array in your program just use imread():

grayimage = imread('4.jpg');

See my Image Segmentation Tutorial in my File Exchange

Image Analyst's File Exchange

for an instructive demo on how to do basic image analysis on an image.
