<p>I would convert your raster to vector. <br>
</p>
<p>Assuming you are on 2.18 (which is what I am currently using) -
open your processing toolbox. At the top of QGIS click on
Processing -> Toolbox. <br>
</p>
<p>1. In your toolbox go to GDAL/OGR -> Conversion ->
Polygonize raster to Vector. Once you change that to a vector file
then go to the next step. <br>
</p>
<p>2. In your toolbox go to QGIS geoalgorithms -> Vector Analysis
Tools -> Count points in polygons. That should add a field to
your new polygon shapefile with the number of points in that
polygon. <br>
</p>
<p>Good Luck. <br>
