Sharpen Image APP
The sharpness is based on "unsharp mask" image processing technique.
All you have to do is playing with two parameters :
Radius - the filter size in pixels.
Intensity - how strong the sharpness is going to be.
** very fast - Takes less than 1 second to sharpen any image and it's super simple **
Note: Sharpening too much might increase noises in the picture, so play with the parameters wisely.
You can save the sharpened photo or share it via Facebook/Whatsapp/Gmail and more.
