blob.stats.g what do image area values mean?

Good day guys.

I have done several blob statistics and calculation of my frame, I extracted blob.stats.g to get information about all the green component in the frame. If I type blob.stats.g I get following information:
col_sum col_mean col_sd col_skew col_kurt blob_area cent_x cent_y pos_sd_x pos_sd_y pos_skew_x

Does blob area show me the amount of pixels with green colour components? I can't get my head around that and really need units for these values to proceed my project.

Help would be very much appreciated.
