- A possible approach is load image, convert to grayscale, Gaussian blur, threshold to obtain a binary image, morph open to remove small noise, find contours, and sort from largest to smallest contour area, the largest contour should be your desired object. Then simply draw this contour with white onto a black mask image to get your resultnathancy– nathancy2021-09-20 23:16:30 +00:00Commented Sep 20, 2021 at 23:16

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
