This paper is focused on wrist localization which is an important step in recognizing hand gestures. While there are many methods for detecting hand feature points as well as for estimating the hand pose, the majority of them assume that the palm region is given and ignore the wrist detection step. However, despite it is a required operation if the gesture(More)
This paper introduces a new method for detecting and localizing hand landmarks in 2D color images. Location of the hand landmarks is an important source of information for recognizing hand gestures, effectively exploited in a number of recent methods which operate from the depth maps. However, this problem has not yet been satisfactorily solved for 2D color(More)
Robot manipulator teaching is a time consuming procedure where qualified operator programs the execution path. In this paper we introduce and discuss the improvement of traditional teaching method with application of hand gesture recognition system. The paper presents the most common robot programming and hand gesture recognition issues and presents the(More)
This article describes the approach to control of human leg dynamical model as a switched linear system. The control scheme consists of fractional and integral order PID controllers. In the paper we analyze the responses of the system depending on the above-mentioned controllers. We focus our attention on angular displacements only. The angular velocity(More)
Aim of this paper is to show the way of reasoning basing on the incomplete information about the initial state. The article presents an algorithm created in order to reason the state of scene from block world basing on incomplete information from two cameras observing the scene from top and side. The algorithm is explained using an example. Additionally,(More)
