The basic algorithm for removing contours from an image goes something like this: Step 1: Detect and find contours in your image. Step 2: Loop over contours individually. Step 3: Determine if the contour is “bad” and should be removed according to some criterion.

Apr 20, 2017 · A lot of applications use digital images, and with this there is usually a need to process the images used. If you are building your application with Python and need to add image processing features to it, there are various libraries you could use. Some popular ones are OpenCV, scikit-image, Python Imaging Library and Pillow.
Among them, scikit-image is for image processing in Python. It is oriented toward extracting physical information from images, and has routines for reading, writing, and modifying images that are powerful, and fast. Scikit-image is often compared to OpenCV, a collection of programs for computer vision that include live video.

Automatically remove image backgrounds in seconds online. Then edit, crop, rotate, fix colors, add shadows - all you need for great photos! They are often simple backgrounds but global thresholding does not work well if parts of the image are near the same color as the background. One deficiency of this method seems to be gaps where the background shows through the item of focus. But it is certainly a good first start, and automating the process is a huge step up from what I do now.
Change the background color. You can change the background color with ax.set_axis_bgcolor, but it will only change the area inside of the plot.This is useful when you have multiple plots in the same figure (a.k.a. multiple charts in the same image) but most of the time is just a headache. Welcome to a foreground extraction tutorial with OpenCV and Python. The idea here is to find the foreground, and remove the background.
