Image enhancement can be considered as one of the fundamental processes in image
analysis. The goal of contrast enhancement is to improve the quality of an image to become …

In this paper, we deliver a new method to remove salt and pepper noise, which we refer to
as based on pixel density filter (BPDF). The first step of the method is to determine whether …

Image enhancement is a fundamental step and plays an important role in image processing,
pattern recognition, and computer vision. Image enhancement can sharpen the edges of …

Distributions of landslide size are hypothesized to reflect hillslope strength, and
consequently weathering patterns. However, the association of weathering and critical zone …

Inspired by the connectivity principle of human visual perception, a new inpainting approach
based on GRNN neural network is proposed in this paper. The missing regions in this new …

A novel filter design for the restoration of the corrupted digital image is proposed in this
paper. The filter design incorporates type II fuzzy system and cuckoo search optimization …

Weld defect inspection is an essential aspect of testing in industries field. From a human
viewpoint, a manual inspection can make appropriate justification more difficult and lead to …

Maize is one of the three cereal crops in the world. The growth status of the maize is often
observed via camera. Segmentation of the maize plant from digital images is the basis of the …

The investigation of form and processes in geomorphology and ecology is highly dependent
on topographic data: a reliable digital terrain representation is in fact a key issue across …

Image quality assessment (IQA) is an objective way to measure the visual quality of an
image, and it plays a crucial role in many image processing techniques. Recently, a lot of …
