Image binarization could be understood as a process of pixel values segmentation of grayscale image into two value groups, zero as a background and 1 as a foreground. In simple humor application of object detection we assume that contrast distribution of foreground is uniformed and without background noise or that variation in contrast does not exist. However, in complex cases previous conditions are inappropriate as variation in contrast exists and it does include background noise, etc. This paper deals with object detection in infrared images for military application using an image binarization step. Military targets are detected in different conditions such as winter condition, summer condition, at night etc. This paper focuses on combination of two methods of image binarization. One is the global binarization method proposed by Otsu and the other one is the local adaptive threshold technique. The global binarization method is usually faster than the local adaptive method and the global method will give good results for specific weather conditions such as object detection in winter condition. In these cases, acquired images have uniform contrast distribution of foreground and background and little variation in illumination. We are looking for an effective method for object detection in infrared images in challenging conditions such as summer conditions or in an urban environment, where there is a shortage of objects of interest. In these cases, we employed local mean techniques and local variance techniques. The experiment results are presented so that we can better choose which method should be employed or what combination of these previous techniques to employ. In order to minimise computational time of local thresholding technique, we employed a combination of two previous techniques. The algorithm was tested in a Matlab environment and the tested pictures were acquired by RayCam C.A. 1884 and thermoIMAGER 160 cameras.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"275 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122748782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gordon, Yangyan Gao","doi":"10.1109/MECHATRONIKA.2014.7018278","DOIUrl":"https://doi.org/10.1109/MECHATRONIKA.2014.7018278","url":null,"abstract":"Modern active safety systems on road vehicles are capable of sophisticated motion control, e.g. for emergency braking, collision avoidance etc. - assisting or potentially overriding the driver to make speed and/or path corrections. The availability of multiple actuators - especially individual wheel braking, active front steering - enables an agile response from the vehicle, even compared to that of the most skilled human driver. For collision avoidance, a typical control approach is to: (a) define a reference geometric path that avoids collision; (b) apply low level control to perform path following. However there are a number of limitations in this approach, addressed in the current paper. First, it is typically unknown whether the reference path is feasible or over-conservative. Secondly, the control scheme is not well suited to avoiding a moving object, e.g. another vehicle. Further, any incorrect choice of reference path may degrade performance, fast adaptation to friction change is not easy to implement and the associated low-level control allocation may be computationally intensive. In this paper we make use of a particle model for initial path planning and guidance, coupled with a simplified optimal controller, used for control integration and low-level actuation. The particle trajectory is only used as a starting point for control integration; the trajectory is not required to be followed. Instead, motion is maximized in a preferred direction away from possible collision, so the particle trajectory is used for prioritization rather than strict guidance. The aim of the present paper is to show the general feasibility of a simple control algorithm based on a linear Hamiltonian function.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116308058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
