A novel robust and high reliability spatial correlation optical flow algorithm based on median motion estimation and bidirectional symmetry flow technique

Abstract

Changing in light condition and representative of noise in sequences cause ineffectively in most of motion estimation techniques. This paper proposes a novel robust spatial correlation optical flow algorithm based on the robust motion estimation and effective confidence technique using bidirectional symmetry of forward and backward flow. Experiment results are comprehensively tested on several standard sequences such as AKIYO, COASTGUARD, CONTAINER, and FOREMAN that have different foreground and background movement characteristic. The experiment is tested under the Additive White Gaussian Noise (A WGN) at several noise power levels (such as A WGN at 25 dB (low noise), A WGN at 20 dB, and A WGN at 15 dB (high noise) respectively) in order to demonstrate effectiveness of the proposed algorithm. Peak Signal to Noise Ratio (PSNR) is used as the performance indicator in our experiment.

Experimental Analysis on Non-Gaussian Noise Robust Optical Flow Using Adaptive-Lorentzian

“…Overturn confidential among filter is an applied method that mix the overturn exclusive collectively with the filter in move processing such overturn confidential with the median filter (OCM) [8] and overturn confidential with bilateral filter (OCB) [9]. For OCM, it identifies the model in concentration regarding bidirectional beside OC along L1 median filter while OCB identifies the model in concentration of bidirectional from OC along the bilateral filter.…”

“…In this paper, we focal point on the first-class of photo reconstruction out of MD concerning geographical interaction (GI) [3] optical flow yet its outlier tolerance fashions such the utilized mixture model concerning adaptive-Lorentzian [4], overturn confidential [5], typical bilateral model [6][7], and overturn confidential with filter [8][9] the place non-Gaussian noises (NGN) alongside along Poisson Noise, Salt & Pepper Noise, yet Speckle Noise are simulated as regards the typical overall performance of NGN tolerance. For performance studying, the sequence is reconstructed beyond result MD regarding every reference model over NGN contaminated sequence and it is tested by means of PSNR in opposition to the ground truth sequence the place the greater rate in PSNR means higher quality.…”

“…More or less in optical flows are impacted by noise where the result in MV is degraded upon increasing of noise. Various techniques were proposed to reserve the efficiency in accuracy under noisy condition such as Barron Kernel [2], bidirectional based [3][4][5], median filter [6], and bilateral filter [7][8][9].…”
