How do you find the sharpness of an image in Python?

Firstly, use the open cv convert the RGB to HSL (luminance is L mentioned in the paper), then get L array. and then used the Laplacian operator to get the LP. Finally, obtain the sharpness value of image based on mathematical form in the paper.

How do you measure sharpness of an image?

Image sharpness can be measured by the “rise distance” of an edge within the image. With this technique, sharpness can be determined by the distance of a pixel level between 10% to 90% of its final value (also called 10-90% rise distance; see Figure 3).

How do you make an image sharp in Python?

To sharpen an image in Python, we are required to make use of the filter2D() method. This method takes in several arguments, 3 of which are very important. The arguments to be passed in are as follows: src: This is the source image, i.e., the image that will undergo sharpening.
