Example of extracting the image contour with python-opencv under noisy conditions, python-opencv Contour
A good method is introduced for extracting the outlines of general images. However, for noisy images, the target objects cannot be captured well.
In this chapter, we will cover:
Eroding and dilating images using morphological filters
Opening and Closing images using morphological filters
Detecting edges and corners using morphological filters
Segmenting Images Using watersheds Watershed
Morphological operations are actuallyChange the shape of an objectFor example, corrosion is "thin", expansion is "fat", you can see it
Morphological operations generally apply to binarization graphs to connect adjacent elements or
This tutorial describes how to use ps to add mosaic effects to an image. the mosaic effect added in this tutorial is very good. we recommend that you use it to your home, if you like it, come and learn it. in image processing, we often need to add
Python-opencv extracts the contour of an image when there is noise, and python-opencv outlines
For general image contour extraction, this blog introduces a good method, but for noisy images, the target object cannot be captured well.
The last time I wrote the edge extraction of A4 paper, I found that there are still a lot of problems in my code, such as the criticism of the static threshold value, as well as the unstructured programming style. So I re-organized, the A4 paper
