Image Background Removal Tool

Build a specialized image background removal tool that processes images from different domains using optimized models.

Requirements

Create a Python module that removes backgrounds from images while selecting the appropriate model based on image content type. The tool should support three specialized processing modes:

1. Anime mode: For anime-style artwork and illustrations
2. Portrait mode: For human portrait photographs
3. Clothing mode: For fashion and apparel images

Core Functionality

Implement a function that:

• Accepts an input image file path
• Accepts a mode parameter (one of: "anime", "portrait", "clothing")
• Processes the image to remove its background using the mode-appropriate model
• Returns the processed image with transparent background
• Saves the output to a specified file path

Model Selection

Different image types require different models for optimal results:

• Anime illustrations benefit from high-accuracy anime-specific segmentation
• Portrait photographs need models optimized for human features
• Clothing items require specialized cloth parsing capabilities

Implementation Details

The function should:

• Read the image from the provided file path
• Apply background removal using the appropriate model for the specified mode
• Handle errors gracefully (e.g., invalid file paths, unsupported modes)
• Support common image formats (PNG, JPEG, JPG)

API

def remove_background(input_path: str, output_path: str, mode: str) -> None:
    """
    Remove background from an image using a specialized model.

    Args:
        input_path: Path to the input image file
        output_path: Path to save the output image with removed background
        mode: Processing mode - one of "anime", "portrait", or "clothing"

    Raises:
        ValueError: If mode is not one of the supported values
        FileNotFoundError: If input_path does not exist
    """
    pass

Test Cases

• Processing an anime image with mode "anime" produces an output file with transparent background @test
• Processing a portrait photo with mode "portrait" produces an output file with transparent background @test
• Processing a clothing image with mode "clothing" produces an output file with transparent background @test
• Calling the function with an unsupported mode raises ValueError @test
