I would like to remove the No Data values of my image in ArcMap. The image has one band. I already tried different ways to do that, but at the end, the No Data values are still in black color. At least, outside the region the black color is removed , but the No Data inside the region is red. I tried the function SetNull and Con (from raster calculator), and reclassify.
if just for visualisation, you can set (NoData) to no color:
or you can use ArcScan tool.
