Aiming at the problem of blurring edge and detail information in the process of image
zooming, this paper proposes a new method of image zooming based on wavelet packet …

Various image priors, such as sparsity prior, non‐local self‐similarity prior and gradient
histogram prior, have been widely used for noise removal, while preserving the image …

With the increasing of needs for machine vision in the field of robotic welding, how to
improve the resolution of weld seam images with high fidelity has become an important …

The alternating current field measurement (ACFM) is an excellent nondestructive testing
method for the inspection of cracks in the steel structure. Generally, the research of the …

Image smoothing is a crucial image processing topic and has wide applications. For images
with rich texture, most of the existing image smoothing methods are difficult to obtain …

The quality of the image edge plays a crucial role in the visual effect of the image, and the
existing image magnification methods keep the edge of the image insignificant. To this end …

The quality of image edges and textures plays a vital role in the visual effect of images. For
kee** the features of image edges and textures better, we propose an image enlargement …

Since the adverse effects may occur when the atmosphere value under un-uniform
illumination is estimated, this paper proposed a dehazing method by using the …

Boundary artifacts and color detail distortion are easily caused by the common multi‐focus
image fusion methods. In order to solve this problem, we propose a two‐stage progressive …

Visual evaluation of cracks in the steel under the coating is an important topic in the
nondestructive testing field. In this paper, the double gradient fusion algorithm is presented …
