Is there anyway to remove the intercept part of the vector points?

Circled part shows intercept points

P.S. Please ignore the red circle, it's not a polygon, it is a hand drawn by me to show the error part

So far I've done: "Select by location" and Geometries Checking. But there isn't a way to work.

    What do you mean with "intercept part of the vector points"? Points are just points, they cannot intersect partially. It is on on off. But you seem to have points which are so close that their symbols, the brows circles, overlap. Is that your problem? – user30184 Dec 02 '20 at 06:22
  • @user30184 What I meant is that some points are touching each other, ignore the red circle which is drawn by me to show the focus of the picture – Wilson Chin Dec 02 '20 at 06:27

    Do you still mean the brown filled circles which are used as point symbols for making the points visible on the map? The point itself does not have dimensions. If point is at coordinates 1,1 only other points at the same 1,1 coordinates intersect with it. – user30184 Dec 02 '20 at 06:38

    Do you have postgis? – BERA Dec 02 '20 at 06:38
  • @user30184 I see, then what can I do for that then. Hmmm – Wilson Chin Dec 02 '20 at 08:18
  • @BERA Nope, my company are using QGIS as it's open sourced – Wilson Chin Dec 02 '20 at 08:19

    I thought postgis was open source aswell. Doesnt matter, I found DBscan clustering in QGIS :). I had the SQL code ready – BERA Dec 02 '20 at 08:42

One way of doing it, which could work:

  1. DBscan Clustering to give each cluster of nearby points a cluster ID, adjust maximum distance: enter image description here
  2. Delete duplicates by attribute by cluster ID: enter image description here
