I have GeoTIFF image. I want to know how to calculate specific area mean pixels values? Is field calculator for(value*count fields) right or get raster properties? Or what can I do?

If you are using ArcGIS the tool you are looking for is Zonal Statistics. You can mark out your your areas of interest with a shape file or feature class, and then use this as input along with your geotiff. I think QGIS has a similar zonal statistics tool if that's the software you are using.

Just to add to @ycartwhelen 's answer. Here is a link to the Zonal Statistics plugin in QGIS. docs.qgis.org/2.18/en/docs/user_manual/plugins/…– GBGCommented Sep 18, 2019 at 20:00
