问题
We have a large number of Images taken from a car for a project. To satisfy privacy norms, we need to detect faces & License Plates and then blur those areas. I came to know of the Emgucv project, and the tutorial given at http://www.emgu.com/wiki/index.php/License_Plate_Recognition_in_CSharp has been very useful to detect Licensplates.
Is there a way of blurring this region using Emgu itself?
回答1:
I don't believe that there is something built-in like what you are looking for.
What you will have to do, like with openCV, is to blur a whole copy of your source image and then copy back the license plate part to the original image.
You can do this using the SmoothBlur method first and then the Copy method that accepts a mask as its second argument.
