Extracting spots from received image data?

Question

JavaScript

Good afternoon.
Received image information from the physical media.
- 128 x 128 elements (pixels)
- There are a few bright spots in the image
- No image signal is taken as { value: 0 }. Maximum value 255.
Received an array of objects of the form:

[
{ x: 1, y: 1, value: 0 },
{ x: 1, y: 2, value: 0 },
// всего 128*128 элементов
// ...
{ x: 1, y: 128, value: 0 },
{ x: 2, y: 1, value: 0 },
// ...
{ x: 128, y: 128, value: 0 }
]

There are several questions:

• highlight spots
  
• calculate the center of gravity of each spot
  

Implementation in JS (Node.JS).
Can anyone give some good advice?

Google "clustering". scikit-learn.org/stable/modules/clustering.html Examples of algorithms in python with a description of their features. There are probably js implementations, many of them are quite easy to implement on your own.
