This paper deals with Sleep Apnea Syndrome (SAS) or, more specifically, Sleep Apnea-Hypopnea Syndrome (SAHS) which affects the population, mainly in the age range of 40–65 years. This syndrome not only has a very negative impact on the sleep of patients, but it can lead to death if not properly treated. Continuous Positive Airway Pressure (CPAP) is an efficient treatment for SAS, but it is uncomfortable...
In this work, we propose a new approach for the connected component labeling task. The developed algorithm is based on a forward and backward scan of the image; from left to right and right to left and row by row. This approach takes into account the eight neighbors of the considered pixel. Unlike other algorithms that need to resolve equivalences in a second scan, with our approach we obtain at the...
This paper discusses the evaluation of two supervised learning based image classification algorithms. The classification subject of this work is part of a complete vision based road sign recognition system to be implanted using the VHDL language on an FPGA card for driver assistance applications. The classification is used in order to classify road scene images into different day times according to...
This work is part of improving the autonomous navigation of mobile robots. In an environment where many obstacles in form of wall are present, the robot must detect obstacles around it, steer to the nearest and track its deviations keeping a desired distance fixed. A joint use of information issued from the three sensors installed on the platform: in front, on the left and on the right are used to...
This work describes the design and development of controllers based on artificial intelligence tried on a newly design of a mobile robot type-vehicle to control behavior for monitoring wall. Two approaches have been optimized and developed to control the robot: The first one is based on Fuzzy logic. This control algorithm combines the different sensory information and provides a suitable control command...
