I have two images. one with stripes and another object with stripes. I would like to extract the object from these two images. These two are uint8 images. Also I want to find the depth of the object by showing images in the surf plot.

Could you give some hint?

I have used imsubtract but it won't give the desire results.

Pprs3 = imread('P1000571-min.JPG');                  % Colour Image
Pprs1 = rgb2gray(Pprs3);                        % Grayscale Image
x = 0:size(Pprs1,2)-1;
y = 0:size(Pprs1,1)-1;
[X,Y] = meshgrid(x,y);                          % Coordinate Matrices (Not Necessary)
figure(1)
meshc(X, Y, Pprs1)                              % Mesh Plot
grid on
xlabel('X')
ylabel('Y')
zlabel('Intensity')
colormap(jet)  
hold on
a = imread('P1000578-min.JPG');                  % Colour Image
b = rgb2gray(a);                        % Grayscale Image
x = 0:size(b,2)-1;
y = 0:size(b,1)-1;
[X,Y] = meshgrid(x,y);                          % Coordinate Matrices (Not Necessary)
figure(2)
meshc(X, Y, b)                              % Mesh Plot
grid on
xlabel('X')
ylabel('Y')
zlabel('Intensity')
colormap(jet)   
hold on
c = imsubtract(Pprs1,b);                  
x = 0:size(c,2)-1;
y = 0:size(c,1)-1;
[X,Y] = meshgrid(x,y);                          % Coordinate Matrices (Not Necessary)
figure(3)
meshc(X, Y, c)                              % Mesh Plot
