Detection of People in Room Using Low-Cost Thermal Imaging Camera
Charvát, Michal ; Kempter, Guido (referee) ; Drahanský, Martin (advisor)
S příchodem průmyslu 4.0 a chytrých domovů se zvyšují nároky na automatické a spolehlivé technologie umožňující detekci živých bytostí. Tyto technologie můžou například pomáhat starším či postiženým osobám s každodenním životem nebo zvyšovat úroveň bezpečnosti na pracovištích tak, že budou hlídat rizikové zóny. Představujeme metodu počítání, detekce a lokalizace osob za použití jediné nízkonákladové termální kamery FLIR Lepton 3 a počítače Orange Pi. Tato práce popisuje proces konfigurace hardwarových součástí celého systému a softwarové řešení problému detekce a lokalizace osob. Naše řešení je založeno na aplikování teplotního filtru s rozmezím lidských teplot, zpracování obrazu s detekcí objektů s pomocí knihovny OpenCV a rekonstrukci 3D scény o známých parametrech. Tento přístup, i ve své jednoduché podobě, dosahuje na naší kolekci dat přesnosti kolem 90 % a nabízí řadu příležitostí na vylepšení.

Creating number concept up to 100
Panovská, Lucie ; Hejný, Milan (advisor) ; Jirotková, Darina (referee)
This diploma thesis deals with third-graders from one of Prague's elementary schools and their understanding of numbers. In addition to the Prodos textbooks, some didactical ideas were taken from the Fraus textbooks, which are aimed at the development of children's understanding mathematics. The experiments were carried out in a classroom and lasted one and a half year. Seven pupils were chosen to take part. The experiments were aimed at gauging their semantic and structural understanding of numbers. The pupils worked individually and were individually interviewed after the experiments. The assumption that pupils use strategies that are not taught in the classroom was confirmed, as well as the fact that the operation of subtraction is much more complicated than addition in mental arithmetic and also in written counting. However, the assumption that the pupils perform better when faced with financial matters as opposed to other situations was not confirmed. It came to light that when creating a verbal task, it is necessary to consider the pupil's understanding of the vocabulary used. Key Words: addition, subtraction, decomposition of number, computation, mathematics, calculative strategies

Numerical competence in animals
Kolbábková, Denisa ; Landová, Eva (advisor) ; Lindová, Jitka (referee)
Numerical competence is a cognitive ability, which enables using number or determining quantity. It contains not only counting, but also lower cognitive abilities such as summation or relative numerousness. Not only people, but also many animals can use knowledge about quantity in some way. This competence is common crosswise the whole animal kingdom, from invertebrate animals (ants or honeybees), across amphibians and fish to birds and mammals. This bachelor's thesis summarizes the research of numerical competence up to nowadays, it describes also different designs of individual tasks and compares the abilities of animals and people. Based on the evolution of numerical competence of mankind is evident that numerical competence has developed progressively and its difficulness increases. In order the previous I postulate a hypothesis that this difficultness could reflect in a phylogeny. In the end of this thesis thus I am devoted to a phylogenetic reconstruction estimate of the ancestral character status in mammals (primates) and I test wheather ecological factors such as the sociality degree and the food extraction progressed simultaneously with the numerical competence. Keywords: numerical competence, summation, relative and absolute numerousness judgement, ordinality, transitivity, conservation...
