Motion Estimation Based Video Stabilization for Old Animation Video Using Wavelet Transform

Efficient Video Stabilization with Dual-Tree Complex Wavelet Transform

We present a new efficient video stabilization method based on Dual-Tree Complex Wavelet Transform (DTCWT). Our method relies on three distinctive techniques in achieving robust stabilization. Our first technique makes use of the linear relationship between the phase changes of DT-CWT and the feature displacement in the spatial domain to perform motion estimation. Our second technique involves ...

Motion Estimation of Old Animation Video Using Multiresolution Approach Based on Wavelet Decomposition

Robust multiplicative video watermarking using statistical modeling

The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...

Domain Global Motion Estimation for Video Stabilization

Video Stabilization, which is important for better analysis and user experience, is typically done through Global Motion Estimation (GME) and Compensation. GME can be done in image domain using many techniques or in Transform domain using the well-known Phase Correlation methods which relate motion to phase shift in the spectrum. While image domain methods are generally slower (due to dense vec...

An Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis

In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...
