“…Thermography is a non-invasive and safe diagnostic method. It is used for diagnostics and monitoring in several fields such as electrical components [8], thermal comfort [9], buildings [10], artworks [11], security [12], ceramics [13] and composite materials [14]. Thermographic examinations allow to analyse thermoregulatory reactions and enable to locate various types of inflammatory processes, which may later cause injuries.…”

The aim of the study was to assess the impact of cryotherapy on changes of surface body temperate and efficiency of thermoregulatory processes in relation to the intensity of cryogenic stimuli. The study included 30 football players and 30 students. Intervention: both groups were divided into three subgroups treated with cryostimulation at -100, -120 and -140°C. Body surface temperature was measured at baseline (before cryostimulation), 5 and 30 min after the treatment. Regions of trunk, lower limbs and upper limbs were examined. The difference of baseline raw curves and raw curves performed directly and 30 min after cryotherapy at the three levels of temperature in both studied groups. Baseline surface body temperature was lower in athletes than in student. Decrease in surface temperature observed after cryotherapy was significant and greater in football players than in students. The drop in surface temperature in athletes by 4.87°in the regions of upper limbs, trunk by 5.9°C and lower limbs by 7.81°C was reported. After 30-min restitution, the surface temperature restored to baseline in all subjects in all examined regions with greater dynamics in athletes. The study results indicate better effectiveness of thermoregulatory processes in football players. In this group, the greatest changes in temperature occurred after cryostimulation at temperature -120°C.Further research is required to assess recommended values of thermal stimuli.

“…Recently, Infrared imaging (IR) systems have gained importance in many application areas such as medicine, industry , military etc., Thermal infrared image is formed due to emission of heat against visual band images that are formed due to light reflection [1,2,3]. Visual band imaging is highly matured and successful due to the advancement of sensor technology, availability of computing power, and high digital storage capacity [4,5,6].…”

In this paper, we propose a Particle Swarm Optimized image fusion framework in Discrete Wavelet Transform domain that combines the thermal image with the visual image to obtain a single informative fused image. Dual tree Discrete Wavelet Transform (DT-DWT) is applied for feature selection and particle swarm optimization (PSO) technique is used to obtain the optimized image. In the fusion process, an optimized weighting factor has been used to form a new composite image with maximized Entropy and minimized Root Mean Square Error (RMSE). Simulation results indicate that the proposed fusion framework results in better quality of the fused image.
