This article describes a method of automatically detecting, counting and classifying logs on a timber truck using a photograph. An image-processing algorithm is developed to process the photograph to calculate an estimate of the number of logs present and their respective diameters. The algorithm uses color information in multiple color spaces as well as geometrical operators to segment the image and extract the relevant information. This information enables the sawmill to better plan internal logistics and production in advance of the (...) truck’s arrival time. The algorithm is robust with respect to external factors such as varying lighting conditions and camera angle, but some inaccuracies remain, mainly caused by logs being occluded or covered in mud or snow.

The presence of vegetation on railway tracks threatens track safety and longevity. However, vegetation inspections in Sweden are currently being carried out manually. Manually inspecting vegetation is very slow and time consuming. Maintaining an even quality standard is also very difficult. A machine vision-based approach is therefore proposed to emulate the visual abilities of the human inspector. Work aimed at detecting vegetation on railway tracks has been split into two main phases. The first phase is aimed at detecting vegetation on (...) the tracks using appropriate image analysis techniques. The second phase is aimed at detecting the rails in the image to determine the cover of vegetation that is present between the rails as opposed to vegetation present outside the rails. Results achieved in the current work indicate that the machine vision approach has performed reasonably well in detecting the presence/absence of vegetation on railway tracks when compared with a human operator.

Levinas se kljub številnim antičnim mitološkim in širšim literarnim reminiscencam in kljub svoji zakoreninjenosti v judovskem duhovnem izročilu vedno znova vrača k izražanju, ki bi lahko doseglo vsakega človeka in ki bi bilo torej v tem smislu univerzalno, ker bi ga bilo mogoče izraziti z razumsko opredeljivimi pojmi. To pa ne pomeni, da bi želel omejiti filozofijo na golo formo logičnih kategorij in jo prikrajšati za njeno pravico do legitimnih vprašanj, ki od samih izvorov dalje ostajajo srčika filozofije v njenem (...) etimološkem pomenu, torej ljubezni do modrosti, ki je veliko več kot samo razum. Ali še bolje – Levinas bo širil polje razuma z novo pojmovnostjo, a njegova modrost ostaja še vedno razumna. V kakšnem smislu pa gre pri Levinasu za »drugačno razumost«, je mogoče odkrivati le postopoma, skozi plasti njegovega »palimpsesta«. (shrink)
