If we compiled our OpenCV libraries with CUDA, or leveraged Numba/JAX, then we can expect better results. If all goes well, an output window should be created displaying real-time background removal. This makes some intuitive sense, as especially small details in a busy background will generate very small contours. Of this information, we only care about the the contours, which are indexed at 1. topic, visit your repo's landing page and select "manage topics.". 10. Taken as a value between 0 and 1. max_area: the maximum area a contour in the foreground may occupy. For this purpose, we timed the run time of the three background removers. That's a cool result. Background Removal using Machine. Finally a mask is generated from the remaining contours and is blended into the original image. Using cv2.imread () function read an image and store it in the bg_image variable. 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. The 0 may be substituted for the path of video file if you dont have one. Image clipping path This technique is used if the subject of the image has sharp edges. If we examine closely, then we will find background remover 3 did the best in preserving the shine on the top of the can. The core image library was created to provide quick access to data contained in a few fundamental pixel formats. min_area: the minimum area a contour in the foreground may occupy. Unfortunately background remover 1 reduced the fidelity of our image. Based on this, we designed our background remover with the following strategy: Given these points, our background remover code ended up as follows: Obviously in method 1, we performed a lot of image processing. The Idea Python Project: Remove Background From Image Without APIs. In todays blog we bring you through our recent journey in developing a basic background remover with OpenCV.
