![]() guideĪ popup window will open, then select new blank GUI as shown in below image, Image Processing with MATLAB GUI Creating MATLAB Graphical User Interface for Image Processingįor building a GUI (Graphical User Interface) for Image Processing launch the GUI by typing the below command in the command window. Like these, there are number of commands in MATLAB which can be used to perform different tasks, you can check the image processing functions in MATLAB by following the link.Ģ. There are many types of color in MATLAB like Jet, HSV, Hot, Cool, Summer, Autumn, Winter, Gray, Bone, Copper, Pink, Lines and spring. Here, in my code I set this command as comment but you can use it by removing the percentage sign. colormap('spring') is used to change the type of colormap of graphic file.= size(‘filename’) command is used to display the size and color planes of a particular graphic file.Imfinfo(‘filename with location’) command is used to display information about the graphical file.For plotting the histogram you always have to convert the image into grayscale and then you will be able to see the histogram of that graphic file. In variable ‘e’, we are plotting the histogram of the grayscale image by using the command imhist(‘filename’)and displaying it in plot on position ‘5’.In variable ‘d’, we are adjusting or mapping the grayscale image intensity values by using the command imadjust(‘filename’)and displaying it in plot on position ‘4’.In variable ‘c’, we are converting the image into binary image or you can say in format of ‘0’ (black) and ‘1’ (white) by using the command im2bw(‘filename’)and displaying it in plot on position ‘3’.In variable ‘b’, we are converting the RGB image into grayscale intensity image by using the command rgb2gray(‘filename’)and displaying it in plot on position ‘2’.To show the image we use command imshow(‘filename’).īelow are few commands to perform some basic processing on uploaded image: In variable ‘a’, we are importing image using command imread(‘filename’) and then making a plot of ‘2’ row and ‘3’ column using subplot(row, column, position) and displaying the imported image on position ‘1’. Copy and paste the below code in the editor window, a = imread ('F:\circuit digest\image processing using matlab\camerman.jpg') subplot(2,3,1) imshow (a) b = rgb2gray(a) subplot(2,3,2) imshow(b) c = im2bw(a) subplot(2,3,3) imshow(c) d = imadjust(b) subplot(2,3,4) imshow(d) e = a e=rgb2gray(e) subplot(2,3,5) imhist(e) imfinfo('F:\circuit digest\image processing using matlab\beard-man.jpg') = size(a) %colormap('spring') To get familiar with all the basic terminology used in MATLAB follow the link. Now, we will write the code for performing some basic operations of image processing in the editor window. Image Processing by using MATLAB Editor Window Here, we will show you both the methods to perform basic operations of image processing in MATLAB.ġ. ![]() In MATLAB, as always, there are two ways to perform any image processing algorithm, one is by directly entering the command in the editor/command window and other is by creating a GUI for the same.
