“…This method requires the operator to know how to use thermal cameras and to have knowledge of thermal imaging and image processing. To simplify the method, a classifier has been developed, which, through computational processing, detects the operating status of components [31]. In the case of an energy audit, in addition to thermography, measurements of electrical parameters are also necessary [32].…”

With technological development and the decrease in the price of electrical appliances for domestic consumers, combined with users’ desire for a certain level of comfort, the number of electrical devices in homes has increased. Although current equipment is largely energy-efficient, the high number of these devices, used simultaneously, has led to an increase in electricity consumption. Electrical installation in homes has been replaced in most cases, but the connections have remained the same, without any checks being carried out in terms of load and operational safety. This paper presents an exploratory case study based on a questionnaire answered by 678 individuals from Romania. The objectives of the questionnaire were to identify the characteristics of the domestic consumer and their opinion on the state of the installation, energy costs, and energy consumption. Based on the analysis, 74.15% of the respondents stated that the power installed in their homes as domestic consumers increased. Based on the analysis conducted on-site, the risk of fire outbreaks in the power supply columns of apartment buildings was identified. To avoid critical situations, it is necessary to periodically check the connection and supply columns so that they are functional and safe to operate.

Infrared thermography is a thermal measurement process that produces images in which each pixel contains a temperature measurement. This technique is very popular in many industries and fields such as preventive and/or predictive maintenance and non-destructive testing, to detect problems more efficiently and safely, but is not currently used effectively. [1] Techniques and technical applications are developed, for the detection and analysis of a certain defect on electronic circuits and electrical equipment. Current thermographic processing software has some limitations, mainly because it is developed for general applications and does not identify a region of interest. The identification of a region of interest with a particular anatomical shape. These shapes are limited when they do not correspond to the complex geometric shape of the area to be characterized, either by exclusion or inclusion of irrelevant data in the evaluation of thermal images. This restriction is observed regardless of the accuracy of the region of interest. This paper presents an image processing technic for localization of MOSFET faults based on thermal, hence the use of segmentation algorithms increases the accuracy of the thermal image analysis.

The constant technological innovation in devices for the acquisition of digital images such as: energy-efficient and high-pixel sensors, memories with greater storage capacity and processors capable of sampling digital signals more quickly, have made it possible to digitize with greater reliability real life scenes in an instant of time, making it possible to analyze and interpret different physical phenomena [1][2][3] such as fractures in materials, evasion of obstacles, weather conditions, injury detection, among others, giving rise to a new line of research called Artificial Vision (AV) focused on generating algorithms to improve image quality, segment characteristics of interest and eventually recognize patterns, in order to make more efficient image processing for the solution of problems in robotics, automation, security, medicine, veterinary, and others. The research aims to develop a database of thermographic images of pregnant and non-pregnant sheep, providing a tool for specialists in the area of computer intelligence and artificial vision.
