平坦検出を用いたランダム値インパルス性雑音検出器 <Abstract> We propose a new random-valued impulse noise detecter from images with using some shape windows. The our method uses directional windows. They use continuity of edge and shape are oblong windows used different angle. In our system, window that has low variation in pixel values is selected from multi windows. For Selected window includes flatness, it has no immediate change in pixel values, therefore decrease threshold of noise detect. Changing threshold in selected window suppres undetection. Extensive simulations indicate that proposed method perform significantly better than traditional method. |
