<h2 _ngcontent-dql-c173=""> Abstract:</h2>
<div _ngcontent-dql-c173="" xplmathjax="">Detection of moving objects in outdoor
environments is an extremely researched topic. However, studies on moving object
detection in complex atmospheric/weather conditions are limited, primarily because
of the absence of any relevant benchmark dataset. To address this disparity, we
introduce a novel benchmark video dataset entitled “Extended Tripura University
Video Dataset (E-TUVD)” which is a diverse dataset of complex atmospheric/weather
conditions. Currently, E-TUVD is the largest video dataset for moving object
detection under degraded atmospheric/weather conditions. The dataset comprises 147
video clips spanning 1-5 minutes in duration of each video clips. Because of the
requirement of evaluating any object detection model, this study emphasizes on
generation of ground-truth images of salient moving objects on E-TUVD. Using this
dataset, we assessed the performance of several state-of-the-art algorithms,
considering both the ability to detect moving objects and visibility enhancement
under such complex conditions. The method with the best performance was used to
investigate the effectiveness of visibility enhancement of atmospheric/weather
degraded image sequences for accurate moving object detection. Results and analysis
reveal that effective enhancement can significantly improve the ability of detection
algorithms under degraded atmospheric/weather conditions to resemble the true
properties of moving objects in terms of pixel oriented binary masks.</div>

<h3>I. Introduction</h3>
<p>Moving object detection has been an active and mature research area in numerous
computer vision applications because of the increasing demand of video surveillance
for security applications. Fundamentally, it is often considered to be a
pre-processing step and a low level task in computer vision applications, which is
interconnected with high level inference tasks such as object localization,
tracking, and classification. Its importance can be anticipated by visualizing the
numerous articles published till date on this topic. Each moving object detection
algorithm is designed to competently address the inherent real-world challenges of
indoor/outdoor scenes, including illumination changes, dynamic backgrounds, ghosting
artifacts, shadows, camouflage effects, etc. [1]–[3]. However, because outdoor
scenes can be degraded by different complex atmospheric/weather conditions, moving
object detection is more complicated under such conditions. Generally, the
North-Eastern (NE) states, along with other states of India, share multiple
international borders, because of which, security plays a vital role in such states.
Under extreme atmospheric/weather conditions, outdoor scenes undergo from
degradation, and suspicious intruders may not be detected by unaided human vision
because of the high loss in contrast. Consequently, electronic surveillance plays an
important role in detecting illegal threats to the state and for real-time detection
of suspicious activities.</p>

</div>If you pass the above HTML to extractFromHtml(), it will fail because the required properties such as title and url are impossible to detect.
It expects HTML with standard structure, a title and some meta tags, e.g:
<html>
<head>
<meta charset="utf-8" />
<meta property="og:url" content="{a valid url here}" />
<title>any title string</title>
</head>
<body>
// put the above content into here
</body>
</html>You can add a url into the above HTML as meta tag, or specify via the second parameter of extractFromHtml():
const article = await extractFromHtml(ABOVE_HTML, 'https://ieeexplore.ieee.org/abstract/document/9082053')
console.log(article)It may return some like below:

//... more content hereSorry for the late response. This webpage is missing <title> element in the head. Once I add it, the parser works. @ndaidong Thanks for the help!
The page URL is IEEE Explorer.
We have applied special filter to only pass the text-heavy elements into the parser, but I still get
undefinedfromextractFromHtml.Any idea of the possible reason?
