Abstract
Versatile Video Coding (VVC) introduces advanced techniques such as
sophisticated intraprediction mechanisms that significantly improve
compression efficiency. However, the increased complexity in
intraprediction presents new challenges in computational load and power
consumption, essential considerations for efficient video coding. This
paper proposes a novel framework that combines discrete wavelet
transforms (DWT) and histogram analysis to optimise the prediction
directions in VVC. Through selective reduction of prediction directions
based on dominant texture orientation and minimising residual energy,
the framework achieves enhanced computational efficiency while
maintaining video quality. Experimental results confirm its
effectiveness, showing minimum rate distortion performance and superior
encoding efficiency compared to other methods in the literature.
