In this paper we evaluate and discuss the application of Legendre orthogonal moments (LOMs) as features for recognition of passenger positions that have been segmented using local thresholding technique. Identification of passenger position in a car is vital in a smart-car system; for example, identifying the passenger position may help in intelligent deployment of the safety airbags. In this study, a total of 1292 images of ten different classes of passenger position have been used. These images have been segmented using the local thresholding technique in order to separate the passenger region from the image background. Then nine LOMs features have been generated for each of the segmented images. The segmentation and feature extraction tasks have been accomplished using C++ programs. The moment features were then fed into the SPSS package for classification using discriminant analysis. The importance of each of the moments in its ability to explain each of the positions is also investigated. The classification results show that 99.5% of the data has been classified successfully. The applicability of the local thresholding technique for the segmentation task is well supported by this very high success rate. We can conclude that the passenger position images investigated has been very well discriminated into the desired passenger position classes. This suggests that the application of local thresholding technique and LOMs is a potential choice for the identification of the various passenger positions
