Question

Hi everyone I wrote this code using MatLab and I need to design a GUI as the following

• Draw Button: to draw the path.
• Scan Button: If I want to take an image using “Image Acquisition”
• Static Text : to show the angels,number of objects and the centers (Individual)
• Axes : To show the image after the processing
  And is there any reference I should read to help me??

The Code:

im1=imread('C:\Users\Shadow Of Dark\Desktop\sample','jpeg');

im1=rgb2gray(im1);

level=graythresh(im1)

bwfram3=im2bw(im1,level);

bw2=bwareaopen(bwfram3,20);

se=strel('disk',10);

bw2=imclose(bw2,se);

bw2=imcomplement(bw2);

[labeled,numObjects] = bwlabel(bw2,4);

imshow(labeled);

numObjects

info=regionprops(labeled,'all');

centers=cat(2,info.Centroid)

hold on;

angles=zeros(1,numObjects);

j=0; 

for i=1:2:2*numObjects-2

  l = line([centers(i) centers(i+2)],[centers(i+1) centers(i+3)]);

  set(l,'linewidth',3,'color','r');

  angles(1,i-j)= atan((centers(i+1) - centers(i+3))/(centers(i) - centers(i+2)))*180/pi;
  j=j+1;
end

angles

Answer 1

Firstly, draw in a paper (or Enterprise Architect, …) what you want and where in the layout. Afterwards, think of the sequence diagram of your process and write it in a paper. Later, divide your code into some functions, related to the steps you have described. Then, create a GUI with the GUI Editor in MATLAB and add a graphical element to your layout. Finally, link each function you have described to your graphical element (read the official help to do it).

(Alternatively, you can do it quicker mixing all these steps, but it is not an appropriate way of doing it).
