Video Compression Schemes Using Edge Feature on Wireless Video Sensor Networks

Table 2

Comparing computation complexity and coding gain with 0.3 bits/sample of four transformations with Gauss-Markov input and intersample autocorrelation coefficient 𝜌≈0.95 per block.

Transform (block size 𝑁=8)	Number of multiplications	Number of additions	Coding gain (dB)
DCT	13	29	0
HLBT	16	42	0.65
LOT	22	54	0.40
LBT	23	54	1.05
