$ python3 main.py
Install ImageMagick (only for macOS)
$ brew install imagemagick (if you are using macOS)
Convert old format to jpeg
$ for i in *.JPG ; do convert "$i" "${i%.*}.jpeg" ; done
Convert old format to jpeg
and downscale image to 50% (Optional)
$ for i in *.JPG ; do convert "$i" -resize 50% "${i%.*}.jpeg" ; done
- The current tool requires that the images to be labeled reside in /Images/001, /Images/002, etc. You will need to modify the code if you want to label images elsewhere.
- Input a folder number (e.g, 1, 2, 5...), and click
Load
. The images in the folder, along with a few example results will be loaded. - To create a new bounding box, left-click to select the first vertex. Moving the mouse to draw a rectangle, and left-click again to select the second vertex.
- To cancel the bounding box while drawing, just press
<Esc>
. - To delete a existing bounding box, select it from the listbox, and click
Delete
. - To delete all existing bounding boxes in the image, simply click
ClearAll
.
- After finishing one image, click
Next
to advance. Likewise, clickPrev
to reverse. Or, input an image id and clickGo
to navigate to the speficied image.
- Be sure to click
Next
after finishing a image, or the result won't be saved.
