Predicting chroma from luma with frequency domain intra prediction [PDF]
SPIE Proceedings, 2015 This paper describes a technique for performing intra prediction of the chroma planes based on the reconstructed luma plane in the frequency domain. This prediction exploits the fact that while RGB to YUV color conversion has the property that it decorrelates the color planes globally across an image, there is still some correlation locally at the ...

Efficient Predictive Coding of Intra Prediction Modes
, 2023 The high efficiency video coding (HEVC) standard and the joint exploration model (JEM) codec incorporate 35 and 67 intra prediction modes (IPMs) respectively, which are essential for efficient compression of Intra coded blocks. These IPMs are transmitted to the decoder through a coding scheme.

Chroma Intra Prediction With Attention-Based CNN Architectures [PDF]
2020 IEEE International Conference on Image Processing (ICIP), 2020 Neural networks can be used in video coding to improve chroma intra-prediction. In particular, usage of fully-connected networks has enabled better cross-component prediction with respect to traditional linear models. Nonetheless, state-of-the-art architectures tend to disregard the location of individual reference samples in the prediction process ...
