This manuscript presents an autonomous navigation of a mobile robot using SLAM, while relying on an active stereo vision. We show a framework of low-level software coding which is necessary when the vision is used for multiple purposes such as obstacle discovery. The built system incorporated a number of SLAM based routines while replying on stereo vision mechanism. The system was implemented and...
Availability of databases is a necessity in the speech processing field. The publically available databases in Arabic language are few. In this paper we describe a rich database for Arabic language. The database is rich in many dimensions: in text, environments, microphone type, number of recording sessions, recording system, the transmission channel, the country of origin, and the mother language...
This research deals with the problem of recognition when only a few samples are available for training of the system. To avoid the low recognition rate caused by such type of speech corpus, automatic techniques for the enlargement of speech corpus are proposed in this paper. These techniques are: lengthening of sample by automatic segmentation, automatic noise addition at different sound-to-noise...
