I would like to get a "blurness" value after using the cannyfilter on a siemensstar image, to check the blurness level. After usind the canny filter you can identify that the sharper image has more lines than the blurry one. So what would be the next step after the canny filtering? Question: How can I determine now which image is sharper? Do I need to check the mean value of the histogram or…? Thanks
