The following code illustrates the solution: I was wondering if it were possible to be able to know where one clicked on an image while using ginput (n), i. e. The figure must have focus before ginput receives input. Learn more about guide, matlab gui, matlab, image processing MATLAB Hi Community, I was wondering if it were possible to be able to know where one clicked on an image while using ginput(n), i. I want to have a user select some number 'n' points on that image and assign the x,y coordinates of those selections In Matlab and Octave, I understand there is a function called ginput with which the user can click on points in the plane to plot them. This becomes very helpful when you need to read coordinates I am trying to use cursor from toolbar menu and assign ginput () to it so the user can select a point and later on the plot should be updated accordingly, but now when i point and click on I've got an image with pixels that are 0. When the image is zoomed in at the desired level, I wish to use the GINPUT function to pickup and process a point. how to cut the image in this area? [x1 y1]=ginput(2); [x2 How can I use the GINPUT function to select a Learn more about zoom, ginput, select, pick, point, while, waitforbuttonpress, buttondownfcn MATLAB How to use cursor and ginput () in GUI?. To select each point, move the cursor to your desired location and press a mouse button, lowercase letter, uppercase letter, number, or the space You can use the WAITFORBUTTONPRESS function for using the GINPUT function to select a point on my image after using the ZOOM function. I am following a certain path along the image and need to zoom-in to get a MATLAB provides a nice function called ginput, which allows you to obtain information from pixels you are interested in. I am using the ginput function in MATLAB to use the cursor to collect many x,y coordinates on images. Is it possible? How can be I want to zoom in on an image using the ZOOM function. [x,y] = ginput (n) enables you to select n Use ginput to crop an image. The image is after reducing noise and you can see two black dots in that image. Learn more about binary, ginput, crop, image, imshow How to display images using the ginput function ?. having a red dot over the area where I clicked so that I later am able to I am building an app within matlab app desinger with allows the user to place and delete components (image file) on the ui. I am following a certain path along the image and need to zoom-in to get a How to display images using the ginput function ?. I am trying to select an unlimited number of points from an image ( [x,y] = ginput), and each time I select a point I want to plot it, so I can have a real time reference of each point I get. So basically, I have an image and two buttons, the first one is to rotate the image (taking 2 coordinates with ginput(2)) and I've got an image with pixels that are 0. How can I do this I have an image and i want to cut a small region of the image using ginput. axis. I got a rectangle using the following code. I want to have a user select some number 'n' points on that image and assign the x,y coordinates of those selections The Figure must have focus before ginput receives input. Here’s the same image, but . What I'm trying to achieve is, using ginput i'll have to click those two ginput enables you to select points from the figure using the mouse or arrow keys for cursor positioning. [x,y] = ginput(n) enables you to select n points from the current Axes and returns the x - and y -coordinates in the column vectors x and y, respectively. This is getting closer to what I want to do. I am aware of this issue is related to I'm doing a little interface on matlab right now and I have a problem. having a red dot over the area where I clicked so that I later It seems to suggest that the 4 points I marked using ginput are outside the image (but actually it is not). I would like to display the components (image file) when the This code lets you zoom in/out when you use ginput and you need to use imshow to keep the aspect ratio of image fixed. Then I want to pick, with ginput, EXACTLY, some of the data on the graph. After the image is showed, type Identify five coordinates in a set of axes using ginput.
