You may also apply methods to pixelate the face if you find the end result more aesthetically pleasing.Įxactly how you “blur” the image is up to you - the important part is that the face is anonymized. Typically, you’ll apply a Gaussian blur to anonymize the face. In this tutorial, we learn two such blurring algorithms - Gaussian blur and pixelation. Given the face ROI, Step #3 is to actually blur/anonymize the face: Figure 5: The third step for our face blurring method using OpenCV is to apply your blurring algorithm. You can then use this information to extract the face ROI itself, as shown in Figure 4 above.
