A Rank-Ordered Marginal Filter for Deinterlacing
This paper proposes a new interpolation filter for deinterlacing, which is achievedby enhancing the edge preserving ability of the conventional edge-based line average methods. This filter consists of three steps: pre-processing step, fuzzy metric-based weight assignation step, and rank-ordered marginal filter step. The proposed method is able to interpolate the missing lines without introducin...
متن کاملA pyramidal image coder using generalized rank-ordered prediction filter
This paper presents a lossy image compression scheme that employs a generalized rank-ordered prediction filter for pyramidal image coding. The proposed prediction method renders significantly reduced variance of the quantizer input. Consequently, the quality of the decompressed image is much enhanced due to the greatly reduced quantization distortion. Both analytical and simulation results show...
متن کاملAcceleration of Directional Medain Filter Based Deinterlacing Algorithm (DMFD)
This paper presents a novel directional median filter based deinterlacing algorithm (DMFD). DMFD is a content adaptive spatial deinterlacing algorithm that finds the direction of the edge and applies the median filtering along the edge to interpolate the odd pixels from the 5 pixels from the upper and 5 pixels from the lower even lines of the field. The proposed algorithm gives a significance i...
متن کاملAdaptive Rank-Ordered Mean Filter for Removal of Impulse Noise from Images
This paper presents a new algorithm for detection of fixed-valued and random-valued impulses from images based on locally obtained statistics. By incorporating the rank-conditioned median (RCM) and center-weighted median (CWM) filters into an impulse noise detection framework, an adaptive mechanism is formed for effectively reducing impulse noise while preserving image details. The rank-conditi...
متن کاملStatistical Ratio Rank Ordered Differences Filter for SeaWiFS Impulse Noise Removal
Due to the 10-bit design of SEAWIFS instrument and the signal transmission, many SEAWIFS satellite images are expected to have lower digitization noise and corrupted impulse noise. In this paper, we first analyze the characteristics of impulse noise and propose a new rank-ordered filter based on the difference of sequence for mean/standard, which is named as Statistical Ratio Rank Ordered Diffe...
