Image Edge Refiner

A tool that removes backgrounds from images with refined edge quality for semi-transparent and complex boundary regions.

Specification

Your task is to implement a background removal tool that produces high-quality edge refinement for images containing fine details like hair, fur, or semi-transparent materials. The tool should handle images with complex boundaries and produce natural-looking cutouts.

Capabilities

Background Removal with Edge Refinement

The tool removes backgrounds from images while applying advanced edge refinement techniques to preserve fine details and handle semi-transparent regions naturally.

• Given an image file "input.png", the tool removes the background and saves refined output to "output.png" with transparency @test
• The output image has an alpha channel for proper transparency @test
• Edge refinement applies foreground threshold of 240, background threshold of 10, and erosion size of 10 @test
