Hello. Thank you in advance for any reply!

 

I use EVI to help extract water surface of a lake. The result is acceptable but not accurate. I don't want to include the extra small pixel plots when counting the total pixel number of the large lake. How can I erase the "noise" pixels? I've marked "noise" out in the second pic. BTW, this is a raster file and has been reclassified into two categories: 0 for Non-lake, 1 for lake (Blue)
