It's hard to say what your immediate problem is with no error message listed, but I strongly suspect that you are using functions that are not supported for HDL code generation. The first several commands in your code are all not supported by HDL Coder. I expect that they all belong in the testbench and not the code you want to generate HDL from. Your code starts with:
clc;
clear all;
close all;
image1=imread('C:\Users\dell pc\Pictures\barbaraa.tif');
imag1=rgb2gray(image1);
im1=imresize(imag1,[256 256]);
im2=im2uint8(im1);
subplot(2,2,1);
figure(1);
imshow(im2);
title('original image');
image2=stdfilt(im2);
subplot(2,2,2);
imshow(image2,[]);
title('standard deviation map');
There's literally nothing in this code fragment that you can generate hardware out of.

You should be able to generate hardware out of the rgb2gray and the im2uint8, perhaps the stdfilt() as well. But you would not want to do the im2uint8 in hardware: it would be a waste of hardware resources (because if the data is floating point in the file then you would need full floating point cores, and if the data is not floating point in the file then the im2uint8 is mostly pointless.) I guess there is a possibility that you might have a use for rgb2gray in hardware, but if so then I would expect that it would be in the context of using the Vision HDL toolbox.
