“…Among its uses in medicine and biology are diagnosis of diseases (e.g. [6,7]) and thermoregulation analysis [5]. In animal welfare science, its applicability in the measurement of physiological stress responses has been explored, such as via eye temperature in cattle [8,9] and horses [10], ear temperature in rabbits [11], and temperature of the comb and wattle in chickens [12], adding to the more conventional methods of stress monitoring in non-human animals (including body posture, heart rate, heart rate variability, and cortisol concentrations in saliva, plasma and urine [13][14][15]).…”

Highlights• Pet dogs were tested in a brief separation test and filmed remotely using thermography• Temperature was analyzed from selected patches of both ear pinnae simultaneously• Social isolation was associated with a significant decrease in ear pinnae temperature• Temperature of the two ears did not differ significantly from each other• Long distance thermography is a useful tool in non-invasive stress monitoring AbstractInfrared thermography can visualize changes in body surface temperature that result from stress-induced physiological changes and alterations of blood flow patterns. Here we explored its use for remote stress monitoring (i.e. removing need for human presence) in a sample of six pet dogs. Dogs were tested in a brief separation test involving contact with their owner, a stranger, and social isolation for two one-minute-periods. Tests were filmed using a thermographic camera set up in a corner of the room, around 7 metres from where the subjects spent most of the time. Temperature was measured from selected regions of both ear pinnae simultaneously. Temperature of both ear pinnae showed a pattern of decrease during separation and increase when a person (either the owner or a stranger) was present, with no lateralized temperature differences between the two ears. Long distance thermographic measurement is a promising technique for non-invasive remote stress assessment, although there are some limitations related to dogs' hair structure over the ears, making it unsuitable for some subjects.

“…The possibility to measure the different aspects of DF and its ulcerative pathology gives to clinicians the chance to both evaluate and weigh up the different components contributing to the genesis and evolution of the cases and to monitor their clinical course as a consequence of the therapeutic interventions. Therefore, it is necessary to establish methods of prevention or early diagnosis for diabetic foot complications [5].…”

Abstract. In this work it is consider the problem of finding the best approximation to characterize the feet temperature distribution. For this study it was consider the nonlinear least squares technique, combined with penalty method, to identify the function that approximate better the data obtained through thermographic images. The preliminary results indicate that the best function approximation is based on trigonometric sums.

“…The technologies for temperature measurement of the foot plantar in diabetic foot management fall in three categories: hand-held dermal infrared (IR) thermometers [5,6,63] (Fig.2.3a), IR camera systems ( Fig.2.3b) [67,68,70,71,73,74], and liquid crystal thermography (LCT, as shown in Fig. 2.3c) [66,69].…”

“…The technologies for temperature measurement of the plantar foot fall in three categories: hand-held dermal infrared (IR) thermometers [5,6], IR camera systems [67,68,70,71,73,74], and liquid crystal thermography (LCT) [66,69]. The use of hand-held dermal IR thermometers in the home environment has been validated by randomised controlled trials for the prevention of recurrent diabetic foot ulceration [5,6].…”
