Noise is an unwanted element that degrades the quality of digital images. Salt and pepper
noise is a type of noise that is introduced in one or more steps during image acquisition …

A two-stage denoising algorithm based on local similarity is proposed to process lowly and
moderate corrupted images with random-valued impulse noise in this paper. In the noise …

Multiclass CNN-based window adaptive optimized filter has been proposed in this research
work to remove impulse noise from colored images. Instead of applying adaptive filter on the …

The median-type filter is an effective technique to remove salt and pepper (SAP) noise;
however, such a mechanism cannot always effectively remove noise and preserve details …

Images are often corrupted by noise during their process of acquisition, storage and
transmission. This alteration usually deteriorates the perception quality of the image. The …

Edge-preserving image smoothing is a fundamental step for many computer vision
problems, and so far, countless algorithms have been proposed. Among these algorithms …

Point cloud data is often accompanied by a large number of noise and outliers, to improve
the quality of point cloud data, this paper proposes a multi-scale point cloud filtering method …
