This paper proposes an efficient motion compensated frame rate conversion method using scaled motion. Different from previous methods where motion estimation and motion compensated interpolation having same search range, proposed method reduces the search range of motion compensated interpolation while search range of motion estimation remains unchanged. Experimental results show that the proposed...
This paper proposes a new hierarchical motion estimation method. Typical hierarchical motion estimation method usually down-sizes video frames by using a fixed sampling position, whereas the proposed method uses a non-fixed sampling position. In the proposed method, the sampling position of the current frame is determined by the motion estimation results of previous frames. Experimental results demonstrate...
In this paper, we propose a motion estimation algorithm for periodic pattern objects that conventional block matching based motion estimation algorithms cannot give reliable results. The proposed algorithm is based on spectral image analysis and statistical object motion calculation. The proposed algorithm doesn't significantly increase computational complexity because it uses Fast Fourier Transform...
In this paper, we propose a novel method reducing motion artifacts in horizontal scrolling text (HST) area which has been frequently occurred during frame rate conversion (FRC) processing. The proposed method takes place in the following two steps: HST area detection and motion vector (MV) correction. The most dominant MV in each horizontal line is referred to as a block line motion vector (BLMV)...
We introduce an advanced local fallback algorithm that is sensible of an object boundary. In previous studies, local vector smoothness (LVS) was used to determine the local fallback ratio. However, LVS in a properly interpolated object boundary results in unnecessary motion. Our local fallback algorithm application is sensible of the moving object boundary and occlusion though spatial and temporal...
This paper proposes an advanced lossless image and video compression method which applies adaptive plane split according to the features of various types of input data. The results demonstrate that the method improves the compression ratio, particularly for video sequences having a large amount of texture and many edge components. It also maintains low complexity as compared to the existing method.
