Auto-Annotation Tool Generates Bounding Boxes Slightly Outside Image Boundaries

[Gpaio574]

While using the auto-annotation feature, I encountered an issue where the bounding boxes generated by the tool sometimes extend slightly outside the image boundaries, particularly near the edges of the images. Despite the bounding box values being normalized between 0 and 1 (as expected in YOLO format), this results in bounding boxes that don't correctly enclose the object within the image.

Image Format: 640x640

In some cases, the bounding box extends slightly beyond the image boundaries, which can be seen in the exported YOLO annotations. Here’s an example of a bugged annotation (normalized YOLO format):

Observed Behavior:
0 0.293685 0.634304 0.587370 0.731392

Upon manual adjustment, the corrected version is:
0 0.293685 0.628883 0.587370 0.742233
