Many vision-based systems suffer from poor levels of contrast and brightness, mainly because inadequate improper illumination during the image acquisition process. As a result, required specified information acquired is not available for particular application. In general, it hard to achieve balance between improvement brightness in enhancement. By introducing nature-inspired optimization enhancement, best features are utilized, complexity related nonlinearity images can be solved with...

Background: Accurate segmentation of the left ventricle in echocardiograms is crucial for diagnosis and monitoring cardiovascular diseases. However, this process hindered by limited availability high-quality annotated datasets inherent complexities echocardiogram images. Traditional methods often struggle to generalize across varying image qualities conditions, necessitating a more robust solution. Objectives: This study aims enhance ventricular developing framework that integrates...

Respiratory rate (RR) monitoring is essential in neonatal intensive care units. Despite its importance, RR still monitored intermittently by manual counting instead of continuous due to the risk skin damage with prolonged use contact electrodes preterm neonates and false signals displacement electrodes. Thermal imaging has recently gained significance as a non-contact method for detection because many advantages. However, lack information thermal images, selection tracking region interest...

This paper presents a machine vision–based precise tool positioning and verification system that may be used with milling lathe machines, so on. For many industrial applications, the accuracy required in machining operations is of order microns. The developed position process involves pixel calibration to compute measure real-world minute dimensions. These measurements are based on two-dimensional spatial correlation sequential images captured from movement resolution 250 µm. thresholded...

Diabetic foot ulcers (DFU) can be avoided if symptoms of diabetic complications are detected early and treated promptly. Early detection requires regular examination, which might limited for many reasons. To identify affected or potentially regions in the plantar foot, region-wise severity must known.A novel thermal dataset 104 subjects was developed that is suitable Indian healthcare conditions. The entire thermogram divided into three parts, i.e., forefoot, midfoot, hindfoot. division...

Objective: A large number of people with obstructive sleep apnea (OSA) also suffer from major depressive disorder (MDD), leading to underdiagnosis due overlapping symptoms. Polysomnography has been considered identify MDD. However, limited access clinics makes this challenging. In study, we propose a model detect MDD in OSA using an electrocardiogram (ECG) during sleep. Methods: The single-lead ECG data 32 (OSAD-) and 23 (OSAD+) were investigated. first 60 min their recordings after...

Image enhancement means to improve the visual appearance of an image by increasing its contrast and sharpening features. This article presents a fusion cuckoo search optimization-based (CS-IE) multiscale adaptive smoothing based unsharping method (MAS-UM) for enhancement. The strategy is introduced deficiency enhanced that suppresses saturation over-sharpness artefacts in order obtain visually pleasing result. ideology behind selection images (candidate) one should have high sharpness or...

Heart rate is typically measured using an electrocardiogram (ECG), which requires patients to wear chest straps with adhesive gel patches that can be abrasive and become uncomfortable for the user. may also monitored pulse oximetry sensors worn on fingertip. These methods inconvenient long-term usages. Besides discomfort, these are not preferred in case of newborn or elderly people as their skins very fragile. Measuring heart a noncontact method could beneficial regular non-obtrusive...

Abstract Radiography is a widely used method for grading and tracking the anatomical changes in knee osteoarthritis (OA) patients. The ease of thermography mapping functional information via skin temperature (Tsk) helps diagnosis various musculoskeletal diseases. There significant involvement soft tissues OA due to complex osteoligamentous degeneration, which may affect Tsk. A total 62 patients with were analysed using thermography. mean Tsk was computed by extracting region interest from...

Tool condition in various machining processes directly affects the quality of machined surfaces. needs to be monitored with purpose evaluating tool life and timely replacing it, if it is not favourable condition. The present work focuses on monitoring through image processing. images single point lathe have been captured before after by a machine vision system. These are processed using MATLAB processing toolbox software has evaluated. Different methods, i.e. Chain code, pixel matching...

Image thresholding is a critical task of image segmentation. Selection the optimal value threshold most important for thresholding. The better quality In this paper, recent swarm intelligence technique (fireworks algorithm) has been used Fireworks algorithm to maximize two functions, namely Kapur and Otsu. Results show that segmentation in case Firewok-Otsu than Firework-Kapur. Comparison results done on basis PSNR value.

Accurate positioning of tool in mechanical devices used smart manufacturing, automation is utmost importance. In applications like manufacturing micro parts, an accuracy micrometer required. Thus, it proposed to opt for economic fast and accurate system which may directly work on the images taken by a high-resolution camera. This contributes estimate position lathe using image processing. The considered move x-y plane. movement calculated from its origin Euclidean distance. coordinates...

The healing trajectory of diabetic foot ulcers (DFUs) is commonly determined through manual inspection, a method which often subjective and prone to errors.In an effort address these limitations, this study explores artificial intelligence-based, computer-aided assessment technique as alternative.This approach leverages the power Hue, Saturation, Value (HSV)-based image fusion technique, integrating thermal visual data deliver precise wound characterizations.Further, deployment instance...
