This paper aims to summarize central findings from a literature review and technical survey
on unmanned aerial vehicle (UAV) techniques for bridge inspection and damage …

Conversion of a color image into a grayscale image inclusive of salient features is a
complicated process. The converted grayscale image may lose contrasts, sharpness …

Decolorization--the process to transform a color image to a grayscale one--is a basic tool in
digital printing, stylized black-and-white photography, and in many single channel image …

Color images often have to be converted to grayscale for reproduction, artistic purposes, or
for subsequent processing. Methods performing the conversion of color images to grayscale …

This paper presents a quick and simple method for converting complex images and video to
perceptually accurate greyscale versions. We use a two‐step approach first to globally …

This paper presents a fast color-to-gray conversion algorithm which robustly reproduces the
visual appearance of a color image in grayscale. The conversion preserves feature …

Color-to-gray (C2G) image conversion is the process of transforming a color image into a
grayscale one. Despite its wide usage in real-world applications, little work has been …

Converting color images into grayscale ones suffer from information loss. In the meantime, it
is one fundamental tool indispensable for single channel image processing, digital printing …

In this research work, a segmentation method for disease spotted leaves using Advanced
Comprehensive Color Feature (ACCF) and Region Growing method captured under real …

In modern digital photogrammetry, an image is usually registered via a digital matrix with an
array of colour filters. From the registration of the image until feature points are detected on …
