    This study leverages High Efficiency Video Coding (HEVC) features for video saliency detection, improving accuracy in the compressed domain. The novel approach reduces computational and storage costs for analyzing human fixations in videos.

    Area of Science:

    • Computer Vision
    • Image Processing
    • Human-Computer Interaction

    Background:

    • Saliency detection predicts human visual attention in images and videos.
    • Current methods often require uncompressed data, increasing computational and storage demands.
    • High Efficiency Video Coding (HEVC) offers rich features within compressed video streams.

    Purpose of the Study:

    • To propose a novel video saliency detection model utilizing features from the HEVC standard.
    • To investigate the correlation between HEVC features and human fixation patterns.
    • To develop an efficient saliency detection method operating directly in the compressed domain.

    Main Methods:

    • Established an eye-tracking database for video saliency analysis.
    • Performed statistical analysis on HEVC features (splitting depth, bit allocation, motion vectors) and human fixations.

  • Developed a Support Vector Machine (SVM) model integrating HEVC features for saliency prediction.

    • Main Results:

    • Identified significant correlations between human fixations and HEVC features like splitting depth, bit allocation, and motion vectors.
    • Demonstrated that the proposed HEVC-based saliency model outperforms existing state-of-the-art methods.
    • Showcased the model's efficiency by avoiding video decoding and raw data storage.

    Conclusions:

    • HEVC features provide valuable information for effective video saliency detection.
    • The proposed compressed-domain approach offers significant computational and storage advantages.
    • This method represents a superior alternative for video saliency detection, especially for compressed video data.
