Is there any open source java based solution to find bluriness/sharpness value of an image

need help for finding an open source java method(not in android) to find bluriness/sharpness value of an image

a quite simple method (variance of the laplacian) is described here:

meaning, all you need is the Laplacian and meanStdDev

you are able to write a program, are you ?

look at our tutorials

go try, and come back with it, if you’re stuck, no ?
