how to do horizontal projection histogram of an image

 Accepted Answer

You mean something like this?
A=imread('pout.tif');%load image
A=mean(A,1);%get the mean (or use sum or max) - these convert the data to double
histogram(A)%generate histogram

Thank you sir ,
I got histogram but how to project the horizontal projection of an image particularly this image
can you please tell me how to do it ....?
There are 3 possibilities for a horizontal projection: a mean, a maximum value and a sum. The mean and the sum differ only in magnitude (and both convert your data to double). The projection convert your 2D image to a 1D signal, so you can use something like bar(A) or plot(A).
