1 to 20 columns are the number of channels.
Coeff of Varience is 7.5 which is saved in variable say thresh_cv which I dynamically getting from some header file.
Now if the mean of channel 1(column 1) is less than 7.5 then remove the channnel else keep that channel.
If mean is greater then 7.5 then remove that channel.
can somebody help me the code for all 20 channels(columns)???
