“…From (8), one can see that once the epipoles are e 0 v ¼ a v 4 and e 00 w ¼ b w 4 , the trifocal tensor can be recovered linearly by rectifying the remaining entries a v 4 and b w 4 . This relationship can be parametrised linearly as t ¼ Ea, where t is a vector containing the tensor parameters, E is a matrix representing the linear relationship in (8) and a is the vector of the remaining entries a v 4 and b w 4 . This is performed by minimising kAEak where AE k k ¼ 1: The matrix A is constructed over the transferred image point using the estimated trifocal tensor.…”

“…Britto et al [19] applied a combination of a PSO and AMEA to reduce the computational complexity and search points. A cooperative motion estimation algorithm based on multi-warm PSO was proposed by Jalloul et al [20]. In this method, information exchange about the motion vectors was found effective in exploiting spatial correlation, refining the motion search and, therefore, leads to a faster convergence and demonstrated improvement in the resulting motion vectors.…”

“…Motion estimation (ME) has a vital role in inter-frame prediction. From the available motion estimation techniques, the block-matching algorithm (BMA) is considered the most popular because of its simplicity and has been adopted in most of the video coding standards, namely H.264/AVC and H.265/HEVC [2]. In this case, BMA frames are broken down to blocks, and individual motion vectors are calculated for each block.…”
