Dear Sir,

Somewhat i found a feasible solution for this problem.... I calculated a histogram of images using JAI and then calculated the SD of the Histogram....

For blank images it came a least SD..... So it was very easy to identify a Blank page rather than a PNG file with some images... Thank you sir...
