Detecting thermal bridges in building envelopes should be a priority to improve the performance of buildings. Recently, thermographic surveys are being used detect bridges. However, conventional methods detecting from images rely on subjective judgment audits. Research has been conducted automatically problems caused by such judgment, but most these studies still early stage. Therefore, this st...

Synthesis, identification and thermal behavior studies of nanoparticles cobalt (II) bromide has been studied in this research. Cobalt (II) bromide was synthesized by planetary high-energy ball mill. The general formula of this compound is CoBr2.6H2O. The synthesized nanoparticles were characterized by Fourier transform infrared spectroscopy and also Size and structure of s...

Problem statement: Current paramount methods and approaches in face identification field rely on facial characteristics; such as location of eyes, length of nose and mouth, regardless the type of medium used to acquire the facial images. The visibility of these facial characteristics varies significantly with environmental factors (e.g., lighting elements). Various researches have been devoted ...

the highest temperatures of the world are recorded in dry and warm climates. this can especially be observed in deserts, where vegetations and soil moisture are very low. as a result, the soil surface receives high thermal energy and its temperature rises up. the lut desert has the above characteristics, making it a suitable environment to prepare land surface temperature (lst) models. objectiv...

In this paper we present a comparative study on fusion of visual and thermal images using different wavelet transformations. Here, coefficients of discrete wavelet transforms from both visual and thermal images are computed separately and combined. Next, inverse discrete wavelet transformation is taken in order to obtain fused face image. Both Haar and Daubechies (db2) wavelet transforms have b...

In paper some examples of the application of the morphological operations in defect detection, using an active infrared thermography are described. The fundamentals of the mathematical morphology and the two methods of the global thresholding are presented. These methods were used to the binarization of the analyzed thermal images. Further, the results of the background estimation, using an ope...

Zheng classification study based on infrared thermal imaging technology has not been reported before. To detect the relative temperature of viscera and bowels of different syndromes patients with pulmonary disease and to summarize the characteristics of different Zheng classifications, the infrared thermal imaging technology was used in the clinical trial. The results showed that the infrared t...

in order to decrease water consumption in agricultural sector, deficit irrigation has been suggested. for preventing a heavy loss in crop yield, management of water stress is essential. common methods for measuring plant water stress such as stomatal conductance are time-consuming and require specialized labor and a large number of measurement. temperature of leaf or canopy surface can be an in...
