Fast mode decision based on systematic deployment of predictive resources for H.264/AVC

“…The effective compact manipulation of predictive resources is verified for the proposed FMD by Table 3, which demonstrates that the achievement of mode Table 4 Performance comparisons between Salgodo's, 16 Kim's, 10 Grecos's 17 and proposed methods relative to JM12.4 with QP 5 24, 28, 32 and 36 using five reference frames in baseline profile by testing QCIF videos, which include V1 decisions is mostly concentrated in the preceding two stages, PSMC and spatial HD. The proposed FMD is compared with the methods 10,15-17 because of the analogous concepts used such as the prior SKIP mode check, the emphasis of threshold design and the manipulation of predictive materials.…”

“…Basically, the fast mode decision (FMD) algorithm can be supported by constructing conceivable thresholding and predicting, which could be associated with motion vector (MV), QP, rate distortion cost (RDcost) and neighbouring MBs. [4][5][6][9][10][11][12][13][14][15] The work in Ref. 9 applies the MVs of neighbouring MBs to spatiotemporal prediction for FMD.…”

“…By progressively comparing the RDcost once a ranged mode, the speedup of mode decision could be, as such, easily obtained. 10,16,17 The work in Ref. 16 compares the RDcosts of SKIP mode, mode 1 and mode 2 in order to immediately check the suitability of treating them as the coding mode.…”

“…12,13 Specifically, the effective statistical threshold settings can acquire straightforward acceleration effect. 4,5,10,12,13,18 In Ref. 10, the predefined correlation threshold addressed searches the temporal most correlated block of coding MB, of which RDcost supports adaptive thresholds for the early termination of searching a plausible best mode.…”

A fast intra prediction method using Hadamard transform in high efficiency video coding

“…Many researchers have proposed the fast encoding algorithms [4][5][6][7][8][9][10][11][12][13][14][15] for AVC/H.264. There are two categories in fast encoding algorithms: fast intra prediction methods [16][17][18][19][20][21][22][23] and fast inter prediction methods.…”
