imgrid 0.1.3

Utility for gridifing images

imgrid

Tool for extracting gridified images from LabelMe JSON annotation format.

Installation

• Requires Python>=3.7
• Install using pip: pip install imgrid

Usage

Use below command to use the tool:

imgrid <json_dir> <out_dir> <width> <height> [--x_stride=<x_stride>] [--y_stride=<y_stride>] [--no_label]

• json_dir is the directory where the LabelMe JSON annotations are saved.
• out_dir is the directory where the extracted images will be saved.
• width is the width of each extracted image.
• height is the height of each extracted image.
• x_stride is the stride in horizontal direction while scanning through each shape. By default this is the same as width.
• y_stride is the stride in vertical direction while scanning through each shape. By default this is the same as height.
• Add --no_label if no label needs to be saved. If it is not added, a txt file containing the image class name will be saved along each extracted image.

The tool will ignore any non-area annotations in the LabelMe JSONs, i.e., it will only consider shape_type that is either polygon, rectangle, or circle.
