AI Technical Summary
Existing video coding systems are inefficient in handling local lighting changes, making it difficult to achieve efficient intra-frame template matching prediction and local lighting compensation, resulting in poor encoding and decoding performance.
By employing Intra-Frame Template Matching Prediction (ITMP) combined with Local Illumination Compensation (LIC), and through a combination of template matching metric and sub-pixel precision filtering, accurate compensation and optimization of local illumination are achieved during video encoding and decoding.
It improves the efficiency and quality of video encoding and decoding, especially when dealing with changes in local lighting, significantly enhancing encoding efficiency and image quality.
