For ex: Theme Copy imwrite (imDIF,'Image difference. Where A is ur image which u want to save,specify the file name and its format. Its not necessary that image needs to be present in ur folder. ![]() This scales the image properly, but the resulting image is still curiously darker (and therefore has less information) than if I hit the "save" button in the figure. imwrite (A,filename,fmt) This is the general format of imwrite. ![]() Update: Based on the comments below, I have begun using "imresize" with the "nearest" option. Any advice? Perhaps it has something to do with the imageplot command? I cannot seem to get that to work in imwrite. How would I program that? I assumed that imwrite() would just write the image directly, but apparently I'm doing something wrong. If A is a grayscale intensity image or a truecolor (RGB) image of class uint8, imwrite writes the actual values in the array to the file. filename is a string that specifies the name of the output file, and fmt is a string that specifies the format of the file. If, however, I utilize the save function in the open figure (image #1) and save it manually, I get exactly what I want, which is that exact image stored on my computer. imwrite (A,filename,fmt) writes the image in A to filename. Some viewers may do that by only displaying the low bits, other the high bits, which depending on the image may result in everything black. Since most displays are only 8 bits, viewers have to convert the 16 bits to 8. Support for reading and displaying 16 bit images is also variable. I then save this image to my computer using the following commands: imwrite(P, 'images/plot.png') Īnd the resulting image is tiny, and missing some of the color information: Digital Image Processing Using MATLAB How to Read, Write & Display Images in MATLAB IntellCity 5.7K subscribers Subscribe 6K views 2 years ago In this video, we will show you how to read an. The only ones available to imwrite are JPEG, PNG and TIFF. I produce a figure using the following code: figure(6),imageplot(P) drawnow I have not been able to find any answers to this, either on StackOverflow or elsewhere. I'm very new to Matlab, though I know a few other programming languages, so please forgive me if this is something simple.
