Hi, I have down sampled an image several times and I want to show each image that has been down sampled like in the document attached below. I would like to show three different figure using subplot. This is fine when only one image is being displayed, but subplot itself adds additional spacing between images. Once the display is correct I can save each image and combine them into a video. I wanted to know, how can I use the subplot function, to plot a line graph of an image X, the value of image X is the difference of image A-B. Before the colorbar is added the plots are exactly the same size, which I would prefer, but when I add the colorbar the imagesc plot is resized to be smaller than before. Here is a small code example.
If you want to display them in a 10x10 grid, there will be 100 images on one screen, so each of them has to be rather small. However, I realized the image is not scaled with the plots Should scale to the height of the adjacent plot subplot 222. Jan: Saen's answer is correct but that is only for a single image plotted 4 times,my problem is that i'm capturing the images from real video and all 4 images are different and i want to plot them in one,if i use the one that Saen suggested it only plot the first image again and again,what should i do now? For further clarification do get back to me! But when i try to subplot that image, using the steps in the documentation, I don't get an error, but the plot does not come up. This code is done using nearest neighbor interpolation. I only give solutions if I can clearly see that they have made a good effort and are stuck.
It is a tad tedious. Can someone please assist me? The imshow function does have a property to remove the border around a displayed image, by using imshow I, 'border', 'tight'. Though one can make arbitrary figures that way and in fact I have done so for this project , it is very tedious. Another possible way of doing this, if your output image J is always the same size, is to pre-allocate a single matrix of the correct size and use montage. Then read the question again and imagine, whether a reader could have enough information to reconsider the problem. These differences occur on the right and bottom borders of the image and are barely noticeable to the naked eye. By default, imresize uses bicubic interpolation and performs antialiasing.
How can I prevent an image from being resized when a colorbar is introduced? Based on the answer of brechmos, when your subplot number is more than 10 subplot, then his code will trigger a error. Data Types: char string cell Name-Value Pair Arguments Specify optional comma-separated pairs of Name,Value arguments. Clarification I am asking if it is possible to produce a figure as described without specifying the position of every element in absolute terms. I had a look at it, but I am having difficulties getting it to work. In dithering, you apply a form of noise to the image to randomize quantization error and prevent large-scale patterns. Meaning I want to put two images in the 1st row and 3 images in the 2nd row. Row and column dimensions of output image, specified as a 2-element vector of positive numbers.
Let's say I want to plot an image that is called A, I can easily get it to show the image histogram. As an additional request, I posted another question in which I mentioned that when I make a subplot figure like this, formatted in exactly the same way you did it, that a title that is supposed to be printed above both figures and centered is erased. Also is there anyway in which I can resize my subplot images to a particular size before displaying on the figures? Using that, you can set the 'position', as seen in help axes. Interpolation Kernel Description 'box' Box-shaped kernel 'triangle' Triangular kernel equivalent to 'bilinear' 'cubic' Cubic kernel equivalent to 'bicubic' 'lanczos2' Lanczos-2 kernel 'lanczos3' Lanczos-3 kernel When method is a 2-element cell array, it defines a custom interpolation kernel. My use case is to show a video alongside plots derived from the video, such that the plots are progressively drawn in step with the video.
This is a general problem in forums: The readers do not have the faintest idea about what you are doing, although it is such obviously for yourself. Instead, describe the problem and what has been done so far to solve it. I mean how can I force images of different sizes to the same subplot sizes on a matlab figure? First of all, remove the call to figure. Hi all I have few problems in matlab : Suppose I have 5 images and I want to plot all of them in a matlab figure window. In short I want to know how I can specifically set the positions for my subplots within the matlab figure window? Your code will draw into the topmost row only.
Click on the subplot which you want to resize. How can I do so? Please how do I scale the image to the plots? From property editor select 'more properties' option. Also is there any way in which I can give a main title to my figure window? But if it is just a one-time thing, maybe the automaticity won't be worth the effort. . This argument is valid only when resizing indexed images,. Is it possible to be done? But I highly recommend to you to save the time and do the image composition in illustrator or latex. Can you edit the example above to include a title in the figure above the individual title figures? Your images will also overwrite one another because subplot counts the subplots in this case, 100 and uses the 3rd argument to determine the subplot to draw into.
I will still vote +1 because this is the correct way to do nearest neighbour interpolation in 2D. I have this requirement often and the most efficient way for me to achieve it is using the third party function, which is a more-or-less slot-in replacement for subplot. Honestly what you're planning to do is quite complicated, maybe even impossible. As for the size of the images, there's really not much you can do. I don't believe there is an easy way to do it.
I have provided an example code below. Or is there a particular reason why you want to do this in matlab? Basically, in subplot I want to plot the original image first, then the first one sampled one and so on. We start by drawing the original image in the first quadrant of the figure, and then drawing each successive downsampled image in a smaller quadrant:. Image A in this case is a 320 x 426 matrix in uint8. In my experience, it all comes down to careful adjustment of the figure size, subplot positions and size through trial and error. Hey, everyone I am new with MatLab, I tried googling this but no success.
Therefore if you want to fill a figure with a 10 x 10 array of images, you need to call subplot 10,10,1 through subplot 10,10,100 in order. I'd like to avoid this. Please note : I am not talking about imresize. Result: However, what if you want to tile the images without any space between them? Any suggestions on how to do this in subplot? This opens a new window each time. Hi all, I have this plot of an image and a set of plots which I plotted together using subplot. If I has more than two dimensions, then imresize only resizes the first two dimensions.
