Target detection in remote sensing images has garnered significant attention due to its wide range of applications. Many traditional methods primarily rely on unimodal data, which often struggle address the complexities environments. Furthermore, small-target remains a critical challenge image analysis, as small targets occupy only few pixels, making feature extraction difficult and prone errors. To these challenges, this paper revisits existing multimodal fusion methodologies proposes novel...
The intima-media thickness (IMT) of common carotid artery (CCA) can serve as an important indicator for the assessment cardiovascular diseases (CVDs). In this paper improved approach automatic IMT measurement with low complexity and high accuracy is presented. 100 ultrasound images from patients were tested proposed approach. ground truth (GT) was manually measured six times averaged, while segmented (AS) computed by algorithm in paper. mean difference ± standard deviation between AS GT...
A man complained of upper abdominal pain and early satiety for one month. An gastrointestinal endoscopy showed nothing specia. CT scan the abdomen was perfromed, which demonstrated a huge heterogeneous retroperitoneal mass close to dorsal wall stomach surrounding aortic celiac trunk. The resected specimen suggested that an un-regular tumor invaded stomach. Postoperative histological examination confirmed it gastric squamous cell carcinoma.
Results simulating time-resolved pulsed electron-beam emission from a triggered four-gap pseudospark device are presented. It is important for many applications to explore the mechanisms of current generated in multi-gap discharge devices. From experiments, it known that emitted electron pulse principally at beginning, characterized by rather short part high energetic electrons followed broad with an average energy half applied voltage. These characteristics have been simulated anode...
The prediction of crowd flow in key urban areas is an important basis for city informatization development and management. Timely understanding trends can provide cities with data support epidemic prevention, public security management, other aspects. In this paper, the model uses Node2Vec graph embedding algorithm combined LSTM (NDV-LSTM) to predict flow. first analyzes correspondence between grid centers, was used extract spatial features. At same time, considering region type, weather,...
In this paper, we investigate the existence and stability of non‐trivial steady‐state solutions a class chemotaxis models with zero‐flux boundary conditions Dirichlet on one‐dimensional bounded interval. By using upper–lower solution monotone iteration scheme method, get model. Moreover, by adopting “inverse derivative” technique weighted energy prove
Three-dimensional plasma diagnosis is crucial for understanding the distribution of physical parameters inhomogeneous plasma. Optical emission spectroscopy (OES) can obtain electron temperature and density by spectrum lines. The premise 3D OES to field at different wavelengths. In this paper, we studied how reconstruct inductively coupled (ICP) jet. purpose work provide an imaging basis future Volume tomography directly two-dimensional images from multiple perspectives, so it used ICP During...
<title>Abstract</title> Purpose The aim of this study was to use computed tomography perfusion imaging (CTPI) compare and analyze the differences in parameters between hepatocellular carcinoma (HCC) surrounding tumor tissue before after transarterial chemoembolization (TACE) diagnose HCC evaluate its curative effect. Methods Twenty-one patients were examined by CTPI four weeks TACE. Regions interest (ROIs) placed (T1), peritumoral-1 cm (T2), peritumoral-2 (T3), background liver parenchymal...
The plasma jet wind tunnel, as a ground simulation device for studying the electromagnetic properties of near-space vehicle sheaths, can help people conduct several studies, such communications and electronic parameter diagnostics. produced by generator has time-dependent variations due to influence power supply oscillations, turbulence, other aspects device. To accurately define experimental state plasma, it is necessary carefully analyze three-dimensional (3D) time-varying characteristics...

It can be to produce the with crystals in different range /spl plusmn/1/spl sim/3/spl times/10/sup -7/ frequency-temperature stability obtained. In procedure MCXOs, supplies standard conditions, measures characteristics uncompensated obtains signal (voltage,...
This paper presents a new nonuniformity correction (NUC) algorithm based on scene-matching for linear scanning focal plane arrays, especially the rapidly developing TDI arrays. The bases matching every two adjacent images in which most parts reflect same scene. response relationship between detectors can be calculated from matched part-pairs. Then it used to complete and adapt drift of with variations environmental temperature. experiments real image sequences demonstrate accuracy robustness...
A flexible registration method for augmented reality in soccer based on the field marks is proposed this paper. By exploiting geometry relationship among centre circle, halfway line and mark of field, images circular points are obtained from image plane. From conjugated two intersection homography between plane space calculated. Furthermore, with constraints that CCD camera skew zero principle point passes through centre, a simple equation deduced to calculate intrinsic parameters camera....
