thermography

 [ther-mog´rah-fe]
a technique wherein an infrared camera photographically portrays the body's surface temperature, based on self-emanating infrared radiations; used as a diagnostic aid in the detection of breast tumors and the assessment of rheumatic joints; also used in the study of pain. adj., thermograph´ic.

ther·mog·ra·phy

(ther-mog'ră-fē),
The technique for making a thermogram.

thermography

(thər-mŏg′rə-fē)
n. pl. thermogra·phies
1. A process for producing raised lettering, as on stationery or calling cards, by application of a powder that is fused by heat to the fresh ink.
2. A technique in which an infrared camera is used to measure temperature variations on the surface of a structure or body part, used diagnostically to produce images that reveal sites of abnormal tissue growth.

ther′mo·graph′ic (-mə-grăf′ĭk) adj.
ther′mo·graph′i·cal·ly adv.

thermography

Imaging An abandoned method for diagnosing breast CA based on an ↑ warmth of skin overlying malignancy; heat is a relatively nonspecific finding that also occurs in mastitis; the technique was abandoned due to the unacceptably high rates of false positivity and false negativity; it has no role in breast CA diagnostics. Cf Mammography, Xeroradiography.

ther·mog·ra·phy

(thĕr-mog'ră-fē)
The technique for making a thermogram.

thermography

A scanning technique in which temperature differences on the surface of the skin are represented as an image or as colour differences. Thermography readily demonstrates areas of inflammation and variations in blood supply, but has not proved particularly useful as an aid to diagnosis.

ther·mog·ra·phy

(thĕr-mog'ră-fē)
The technique for making a thermogram.

We also used Lepton (FLIR, USA) [4] as a thermal camera and Omnivision (Omnivision, USA) [5] as a RGB camera to obtain thermal videos and red, green, and blue (RGB) videos.

Thermal video has been used successfully for night-time pedestrian detection, an area of particular importance because pedestrians maybe less visible to drivers at night and are therefore at a greater risk of collision [12].
We then applied the motion segmentation to a 2-second segment of the "train station video," the "thermal video," and the "winterstreet video." The results are shown, respectively, in the videos of Figures 17, 18, and 19 (see Supplementary Videos S9a and S9b, S10a and S10b, and S11a and S11b, resp., for full videos).

Thermal videos of the soil surface were recorded with an Optris PI-160 portable infrared video camera (Optris GmbH, Germany) with an optical resolution of 160 x 120 pixels, a thermal resolution of 0.1[degrees]C, an accuracy of [+ or -]2%, a frame rate of 100 Hz, and a lens with a view field of 23[degrees] x 17[degrees] and focal length of 10 mm.
Soil surface thermal videos were recorded with the infrared camera throughout the experiments.
To verify real-time operations of the proposed block-based simple flame detection algorithm, 10 IR thermal videos and a real-time DSP board were used to test the algorithm, as shown in Fig.
For comparison of correct-detection performance and real-time processing capability, pixel-based flame detection algorithm based on the proposed algorithm was tested using same 10 IR thermal videos and a real-time DSP board.
