These lines convert both the mask and the frame to the required data types they need to be to blend together. Then I created an empty integer array of zeros, with the size of the car image. The 0 may be substituted for the path of video file if you dont have one. What makes Python multi-purpose are modules of prewritten code, sometimes referred to as libraries. Especially with both gaussian blur and color binning operations. In the last step save the processed image at the location stored in output_path using output.save() function. NOTE: When I downloaded your image I had to crop it to get the one with the car. Under ideal conditions, the algorithm worked near flawlessly, but some additional tweaking may be needed for complex or busy backgrounds. The rembg command has 3 subcommands, one for each input type: Additionally, when applying Gaussian Blur and binning, we lost a lot of detail in our image. Today I'll add a few extra lines, and I'll remove the background from my camera feed. Here we can see a screenshot of my office, and the removed background sample. Save the code as background_remover.py. In the following you can find the source code. Finally, I used the dilated image as a mask for the original image, using the cv2.bitwise_and() function, and the result lies in the following image: If you have a lot of images you will probably need to create a tool to annotate the markers graphically, or even an algorithm to find markers automatically. You first draw a few lines on the foreground and background, and keep doing this until your foreground is sufficiently separated from the background. Go back to Step 10 and re-run the code.

Execute the following command in the Terminal Window to install it: Step 2: Read the image using the path of the image. 1. It's not them. Any avenues of inquiry would be helpful. As the name suggests, BS calculates the foreground mask performing a subtraction between the current frame and a background model, containing the static part of the scene or, more in general, everything that can be considered as background given the characteristics of the observed scene. Unlike edge detection, finding contours will find prominent shapes within the image. Instead, the below flow-chart outlines the method I'll use: First, we'll take the image and convert it to black and white. This key first step pre-processes the image to help differentiate any objects. In order not to lose image detail we also decided not to perform Gaussian Blur nor image binning. The Pillow library, a derivative of the Python Imaging Library (PIL), aids in giving Python interpreter image processing capabilities. I recommend using OpenCV's grabcut algorithm.
