Sensor for Distance Measurement Using Pixel Grey-Level Information

open access: yesSensors, 2009
An alternative method for distance measurement is presented, based on a radiometric approach to the image formation process. The proposed methodology uses images from an infrared emitting diode (IRED) to estimate the distance between the camera and the ...

Grey level co-occurrence matrix (GLCM) for textile print analysis [PDF]

open access: yesTekstilna industrija, 2022
Print mottle is a print defect. This print defect has great attention in print quality assessment. Print mottle is determined by the grey level co-occurrence matrix (GLCM). An important parameter in the GLCM processing is the direction angle of pixels in

Community structure and composition of litter spiders (Arachnida: Araneae) and influence of macro-climatic factors on Parque Ecológico Jatobá Centenário, Morrinhos, Goiás, Brazil

open access: yesJournal of Threatened Taxa, 2015
Spiders are a diverse group and are considered to be good bioindicators due to their sensitivity to variation in biotic and abiotic factors.  Despite this the taxonomy of the Araneae is poorly known, particularly in the tropical and subtropical regions.

Grey Level Estimation for Discrete Tomography [PDF]

open access: yes, 2009
Discrete tomography is a powerful approach for reconstructing images that contain only a few grey levels from their projections. Most theory and reconstruction algorithms for discrete tomography assume that the values of these grey levels are known in advance.
