To make our lives easier, let’s take a look at a literally smaller problem. We’ll convert the images to grayscale and focus on a 50x50 pixels square patch from both images. Grayscale test images 50x50 pixels square patch from both images Zooming in makes the blurry patch look really… blurry. But how do we define our interpretation of this blurrines...
“I know!”, we might say. The edges in the blurry image are not so clear. In image processing speak, an edge is a region of quick color (or brightness in grayscale images) change. The quicker the change, the clearer, or sharper, the edge. So, in order to find edges, we need to investigate how neighboring pixels look in comparison to each other. For ...
We now know how to identify regions with edges, but how to tell wether or not they are “clear”? In the same sense that edges represent regions of “quick change” in our image, clear edges represent areas where the edges themselves change quickly (the “gradient of the gradient”). This notion of “change of change” is captured by the Laplacian filter. ...
I collected around 60 blurry and sharp pictures to make up a little training set. These images look a lot like the ones in the beginning of the post. They include some varying background, slightly different perspectives, but mostly contain the same answer sheet. If you want to play around with it, here is the tarballwith the training images.
With the Sobel and the Laplacian filters in our toolbelt, we’re in a good position to use them as building blocks in computing different measures of how blurry an image is. The 2011 paper “Analysis of focus measure operators for shape-from-focus” present a survey of 36 (!) different techniques to measure focus on an image. I came across this paper ...
