An effective weighted vector median filter for impulse noise reduction based on minimizing the degree of aggregation
Abstract Impulse noise is regarded as an outlier in the local window of an image. To detect noise, many proposed methods are based on aggregated distance, including spatially weighted aggregated distance, n nearest neighbour distance, local density, and angle‐weighted quaternion aggregated distance....
