resize-image

resize-image resizes the image and associated shapes in a JSON:

Usage

As the argument, you can pass either a JSON file or directory of JSON files.

labelmetk resize-image [OPTIONS] FILE_OR_DIR...

• --scale [SCALE]: Scale of image resizing; typically 0 < SCALE < 1. It runs with SCALE >= 1, which upscales the image by linear interpolation, but the image quality won't increase, so not recommended.

Example: Resize image for a JSON file

Pass a JSON file:

labelmetk resize-image small_dataset/2011_000003.json --scale 0.5

Example: Resize image for a directory of JSON files

Pass a directory that contains JSON files:

labelmetk resize-image small_dataset/ --scale 0.5
