Robust global based spatial correlation optical flow in bidirectional confidential technique with bilateral filter

Abstract

Noise is one of the main factors that impact the performance of optical flow where the result in motion vector of optical flow is degraded. Many areas in advance require a result of optical flow as a preprocessing such as super resolution image reconstruction, robot vision, motion estimation, edge detection, motion tracking and etc. Then, the accuracy in the result of motion vector from optical flow is very importance. This paper introduces the robust model of optical flow by using bidirectional confidential technique together with bilateral filter for global based spatial correlation where the efficiency of the proposed model is evaluated by Peak Signal to Noise Ratio (PSNR) under noisy condition.

Experimental analysis of non-Gaussian noise resistance on global method optical flow using bilateral in reverse confidential

“…The bilateral in reverse confidential (B-RC) [21] is the fusion approach that combines the traditional bilateral function in correspondence with the reverse confidential approach. The process of B-RC is shown in Figure 1.…”

“…The concept of the reverse confidential in optical flow and the bilateral function in optical flow was proved and presented an effective result in noise resistance. This paper focuses on the use of the fusion approach among the bilateral filter and the reverse confidential called the application of bilateral in reverse confidential with G-OF [21]. The objective of this paper is to analyze the performance in the non-Gaussian noise resistance on global method optical flow using bilateral in reverse confidential.…”

Verification of Video Reconstruction Using Bilateral-Reverse Directional Global Based Optical Flow over Non-Gaussian Noise

“…B-R is a fusion technique using RC correspondent with BF on GBOF. According to the original framework of B-R [7], it presented very well performance over Additive White Gaussian Noise. The process flow of B-R is illustrated in Figure1.…”

“…Then, we used Peak Signal to Noise Ratio (PSNR) to be a verification indicator with the regular ground truth video. We verified Bilateral-reverse directional technique (B-R) [7] against with the other robust techniques on GBOF. There are regular reverse directional certainty algorithm [8], and regular bilateral filter [9][10][11].…”
