Getting Started

Installation

To install imgmatch, use the following command:

pipx install imgmatch

Usage

Run imgmatch on your desired image or directory of images:

imgmatch /path/to/image/or/directory --scale-start 0.5 --scale-end 2.1 --confidence 0.8 --num-processes 4

Customizing Parameters

You can customize the search parameters to fit your specific needs. Here are some of the options you can adjust:

• --scale-start: Starting scale (default is 0.5).
• --scale-end: Ending scale (default is 5.1).
• --confidence: Confidence threshold for template matching (default is 0.8).
• --num-processes: Number of processes for parallel execution (default is 6).
• --angle-start: Starting angle for rotation (default is 0).
• --angle-end: Ending angle for rotation (default is 360).
• --angle-step: Angle step for rotation (default is 90).
• --template: Path to template image (default is None).
• --output-dir: Path to output directory (default is current directory).
