👉 Unsharpness is a mathematical concept in image processing. It refers to the ability of an object or shape to be made more visible when it is not as sharp and distinct as it might appear under ideal conditions. This capability can be achieved by using various techniques, such as sharpening, blurring, or adding noise. In other words, unsharpness allows for a more nuanced view of objects in images, making them easier to identify and manipulate. It also helps to reduce the amount of noise
