I had a recent project of processing batches of images. I used PIL for it. I needed to subtract the background from all the images. Thankfully, all the images were photographed against the same background, so I just manually removed the subject from one image in e.g. MS Paint, fed that image of just the background into PIL to get the RGB values of each of its pixels, then subtracted all ...

Image Smoothing using OpenCV Gaussian Blur. As in any other signals, images also can contain different types of noise, especially because of the source (camera sensor). Image Smoothing techniques help in reducing the noise. In OpenCV, image smoothing (also called blurring) could be done in many ways.

OpenCV Background Removal on AWS Lambda uses a three step method to remove the background. First, the python lambda function uses OpenCV's deep neural network (DNN) to identify areas of interest in the image. These areas are given as probability of being part of an object, a person or a dog for example. This results in a highly pixelated image ...
