“…As shown in Fig.5. the CTU can be split into MxM, M/2xM/2, M/3xM/3, and M/4xM/4 with M equal to 64 [28],depending on their respective distortion rates. Furthermore, each CU can be split into prediction units (PUs) {symetric: MxM, MxM/2, M/2xM, M/2xM/2, and asymetric: MxM/4, Mx3M/4, M/4xM, and 3M/4xM } then into transform units (TUs) [29].…”
