i convert rgb image to binary image,the rgb image is of agriculture crops either side with midlle path,i convert that rgb to binary image by making path as white and remaing trees as black, it gives a image of size 435*1200 means the matrix is also of same size.now i have to scan each row and find the pixel column number whose value is 1 and add the column numbers to find the mean distance in between them.
this has to be performed for all the 435 rows.
please help me by answering this and if possible give me a code.

It's hard to tell something without any data or example? Can you provide something?

now i have to scan each row and find the pixel column number whose value is 1 and add the column numbers to find the mean distance in between them.
Let say bw is the binary image
[r c]=find(bw==1);
Do with loop or other way to get the mean of individual row

for i=1:length(r)
[r,c]=find(bw(i,:)==1);
col_mean(i)=mean(c);
end
col_mean are the corresponding mean data of cloumns in respective rows. I have no clue what exactly you are trying to do.

You need to take your binary image (which unfortunately you forgot to attach) and rotate it using the radon transform and imrotate() like in the attached example.
Then, once you have the crop rows aligned with the image edges, you"
- Invert the binary image (to get space instead of plants) and
- Call imclearborder() to remove any space not fully visible in the image, then
- Scan across the rows (or columns) getting the width of the spaces on each row (or column) using regionprops()
- After all rows have been scanned, compute the mean spacing.

I thought you had an already segmented photo of an overhead view. Why is this needed? Why some complicated vision system when simply using a tape measure will do the job much more simply?
You should look into the camera calibration capability of the Computer Vision Toolbox - it can do that.
