recDir = fullfile('C:\','Users','User','Documents','MATLAB',cas,strrep('carmeri','i',int2str(num_carmer))...
         ,strrep('linetracki','i',int2str(num_photo)));
mkdir(recDir);
imwrite
(averaged_bw1,re,[recDir,'\',strrep('linet','t',num2str(numt)),'.png']);%what code should I write in this part

Try exportgraphics() if you have R2020a. Otherwise use export_fig().

Hey, I think you need to use the 'imwrite' command instead of 'imwrit'.

If it is a typo, you can refer to this answer to save the image at your desired directory with the name you want.

Please go through imwrite documentation as well

what's I mean is that i have a background image and i had used hold on to see if the line i what if it correct，and i what to save every image to check if there are something wrong ，so i 'm thinking if i can save two thing

imwrite() won't work unless the blue has been burned into an RGB image.
