Efficient Implementation of Multi-View Video Compression for High Performance Application

Abstract

Multi-view applications provide viewers a whole new viewing experience and multi-view video coding (MVC) that plays a key role in distributing multi-view video contents through networks with limited bandwidth. The main objective of Multi-View video compression is to increase the compression ratio with minimum loss. The Hierarchical B picture (HBP) prediction structure is very helpful in multi-view video coding due to a reduction in the computational complexity in MVC and improves the coding efficiency. In this paper, Low Cost Multi-view Video Coding Discrete Wavelet Transform (LC-MVC-DWT) is introduced to improve the Peak-Signal-to-Noise-Ratio (PSNR) value, Application Specified Integrated Chip (ASIC) performances and Field Programmable Gate array (FPGA) performances. FPGA results showed that LUT, slices, flip flops, frequency improved and also ASIC results showed that area, power, delay, Area Power Product (APP) and Area Delay Product (ADP) improved in the LC-MVC-DWT technique compared to the existing methods.

“…Additionally, this method was achieved less computational time and increases bit rate, theses performance metrics were computed in Matlab for different frames. In 180nm technology, 1.15% of area, 0.86% of power, 2.06 % of delay reduced using LC-MVC-DWT [14]. In 45nm technology, 0.78% of area, 0.64% of power, 0.36 % of delay were reduced using LC-MVC-DWT [14] method than the conventional methods.…”

“…Figure.13 shows that proposed method obtains an excellent coding performance in terms of the RD performance and encoding time saving. In experimental, the RD cost is computed for three different types of the video coding technique such as LC-MVC-DWT [14], LC-MVC-HCD method based on with and without genetic algorithm. Compared to RD cost performance of three methods, the LC-MVC-HCD-with GA method was achieved better RD cost compared to the other two methods such as LC-MVC-DWT, LC-MVC-HCD without GA. A RD model used for inter predictions, which models as the rate as linear combination of the non-zero quantized transform coefficients and sum of absolute values of the all non-zero coefficients separated by quantization step size.…”
