XML generated are distorted when opened in LabelImg annotation tool about auto_annotate HOT 7 CLOSED

@DeepakShanthaiah I already had this problem, but I thought that was fixed. This is probably happening because the proportion of the image is not the same as the XML in the generation process. To confirm this hypothesis, check your output JPG file, the generated bounding boxes are in the correct positions?

Your problem may be here:

In this line of code, the bounding box position is set, but if for some reason your im_width/height is not correct, the proportion of the box will not be correct.

Please, let me know about your findings!

Hello @AlvaroCavalcante ,The result folder where I get the output image in that the bounding boxes are exactly on the part. Also, the co-ordinates of the bounding boxes fits exactly when I drag that bounding box on the particular part in LabelImg tool and this is tedious task to drag and place that bounding boxes everytime for multiple class.If it gets auto annotated on the part itself if not 100% atleast 90% of that part it will help us .

I did went through that line and I am not able to figure out why is this issue.

If the bounding boxes in output jpg image is perfect then why is it generating XML file with distorted localization of annotation. I guess something is going wrong while writing XML file.

Any alternative suggestion you can help me with to tackle this ?

@AlvaroCavalcante , I just tried checking the proportion of image:
In my input image : width =640 and height =480
In Xml file which is generated the width and height are same as above but the output image in result folder has width =636 and height = 482, so here is the issue I believe. What should I do to overcome this ?

@DeepakShanthaiah don't worry, we'll solve your problem! Well, I've done the following test:

• I got an online image of a leaf disease (my object detection model is trained for it) and resized with the same resolution as your image (640 x 480):
  
• After that, I ran the script and got the following JPG output:
  
• I copied and pasted the generated XML file in the same folder as my original image (without detections).
• Then I opened the LabelImage software, and clicked on "Open Dir", selecting my directory with my image and XML.
• The result is the bounding box in the right position, as saw in the output JPG.

Important detail - please, note that your XML and JPG MUST have the same name, not only in the file but inside the tag in XML, here is my working example:

And inside the XML file:

If you have trouble with the file name, let me know, I already implemented a solution to solve this, passing the same name to the image and XML file inside generate_xlm class.

@DeepakShanthaiah I've added an update on branch master to get the XML name automatically based on the JPG filename.

Hello @AlvaroCavalcante , Thanks for your response . The issue is resolved and it helped me reduce my time in annotating.
