Segmentation method of the abnormal area of coal infrared thermal image

open access: yesGong-kuang zidonghua, 2022
Infrared radiation can reflect the damage of coal and rock under load, and can be used to monitor and prevent the dynamic disaster of coal and rock. But the infrared thermal image generated by the infrared thermal imager has low pixel resolution and ...

Quantitative analysis method for infrared characterization of coal damage under load based on image enhancement and pixel extraction

open access: yesGeomatics, Natural Hazards & Risk, 2023
To explore the quantification method of infrared thermal image characteristics in the coal loaded-damage process and better reflect the infrared precursor information and damage evolution of coal, in this paper, a new index based on the color extraction ...

Applications of thermal imaging in avian science [PDF]

open access: yes, 2013
Thermal imaging, or infrared thermography, has been used in avian science since the 1960s. More than 30 species of birds, ranging in size from passerines to ratites, have been studied using this technology.

Cluster-analytic classification of facial expressions using infrared measurements of facial thermal features [PDF]

open access: yes
In previous research, scientists were able to use transient facial thermal features extracted from Thermal Infra-Red Images (TIRIs) for making binary distinction between the affective states.

Estimation of soil and vegetation temperatures with multiangular thermal infrared observations: IMGRASS, HEIFE, and SGP 1997 experiments [PDF]

open access: yes, 2001
The potential of directional observations in the thermal infrared region for land surface studies is a largely uncharted area of research. The availability of the dual-view Along Track Scanning Radiometer (ATSR) observations led to explore new ...

Thermal infrared plasmonics [PDF]

open access: yes2011 XXXth URSI General Assembly and Scientific Symposium, 2011
We examine a new class of infrared (IR) plasmonic devices that convert thermal radiation into bound surface plasmon polaritons (SPP's). The coupling of these SPP's into nanometer scale metal insulator metal (MIM) channels is investigated both theoretically and experimentally.

FUSING PASSIVE AND ACTIVE SENSED IMAGES TO GAIN INFRARED-TEXTURED 3D MODELS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Obtaining a 3D description of man-made and natural environments is a basic task in Computer Vision, Photogrammetry and Remote Sensing. New active sensors provide the possibility of capturing range information by images with a single measurement.
