Dear all,
We have downloaded the road dataset online, in that, they have created annotation (Ground truth) for all the original images. The annotated images are in XML format, and we could open the XML data in notepad.
How to extract the information of annotated data (XML) file in MATLAB. How to view the information of annotated data (XML) as an image format.
One sample original image (000001.jpg) and its annotations (Ground truth (000001.xml)) files are attached here.
Would you please let us know that how to proceed further? Any help would be highly appreciable.
Thanks and regards
Sukumar.

There are many ways to read text files, and there are many ways to parse XML text to a struct. What did you try already? How did the results differ from what you expect or want?

It's impolite to tag people like that. There isn't much information about processing XML files, but there should be enough to get you started. See here https://uk.mathworks.com/help/matlab/ref/xmlread.html

(tested)
T = readtable('000001.xml');
img = imread('000001.jpg');
x = T.xmin;
width = T.xmax - x + 1;
y = T.ymin;
high = T.ymax - y + 1;
img2 = insertShape(img, 'rectangle', [x, y, width, high]);
imshow(img2)

Is it possible that you forgot to mention that you are using an older MATLAB version? I tested the code before I posted. I would have shown the output but it was a nuisance to attach an XML file.
