    This study introduces a new image compression method using parameter-assistant inpainting (PAI) to reduce visual redundancy. The approach significantly outperforms JPEG, saving 76% bit-rate in featured regions with comparable quality.

    Area of Science:

    • Computer Vision
    • Image Processing
    • Data Compression

    Background:

    • Exploiting visual redundancy is crucial for efficient image compression.
    • Traditional methods like JPEG may not fully leverage region-specific characteristics.
    • Parameter-assistant inpainting (PAI) offers a novel approach for image restoration.

    Discussion:

    • The proposed method categorizes image regions into 'featured' and 'non-featured' based on predefined models.
    • Featured regions are compressed using a few parameters, while non-featured regions use conventional coding.
    • PAI reconstructs featured regions at the decoder using provided parameters and contextual information.

    Key Insights:

    • The parameter-assistant inpainting (PAI) effectively restores complex image regions.
