This paper mainly realize in-flight localization and alignment for carrier-based aircraft in a three-dimensional fleet network. A 3D node localization scheme is presented based on weighed-multidimensional scaling, which adopt spherical locating in the initial stage, and adaptively choose source nodes with high relative reliability to achieve position update. Then a robust filter algorithm is applied...
In audio retrieval, endpoint detection is a crucial step of front processing. This paper presents a MP3-based approach for robust endpoint detection under different types of noises. Firstly, the modified discrete cosine transform (MDCT) coefficients and scale factors (SCF) are extracted from MP3 file. Then, combined with the selection of SCF, a set of MDCT coefficients of white noise are used to enhance...
This paper presents an eye-gaze tracking system based on the image processing. All the computations are performed in software and the system just needs a PC camera attached to the user's computer. We first extract the facial regions form the images using the skin-color model and connected-component analysis. Then the eye regions are detected by employing the rules and area segmentation. After the...
