Fmask 4.0 Standalone without GUI changing parameters #1

Open Doktor-Hu opened 6 years ago

Doktor-Hu commented 6 years ago

Dear Fmask developer,

I am now using Fmask 4.0 in the Command Prompt, I want to change the default parameters according to Fmask 3.3:

Fmask_4_0 4 6 1 50

first parameter (4) is the number of pixels dilated for cloud (default is 3) the second parameter (6) is the number of pixels dilated for cloud shadow (default is 3) the third parameter (1) is the number of pixels dilated for snow (default is 0), and the last parameter (50) is the cloud probability threshold with default value of 22.5

Then it appeared that Cloud/cloud shadow/snow dileted by 52/54/49 pixels, cloud probability threshold of 53.00%

I would like to ask what is the correct way to set up these parameters.

Thanks and with regards, Zhongyang
