This paper presents the test results of the Query-by-singing/humming(QbSH) system, which are measured with varying the pitch extraction algorithm. The test is for verifying matching engine of our QbSH system of which database is constructed from polyphonic recordings such as MP3 files. For the test, we used 3 different pitch extraction algorithms, and the experimental results are obtained with our...
Query by humming (QBH) is a method of searching for a songs in a multimedia database system that contains the melody descriptions of songs. The database of songs can be searched by hummed queries. The user hums a melody into a microphone that is connected to any handheld device and the QBH system searches the database of songs which are similar to the input query and returns the result to the user...
This paper proposes new features for motion recognition. Higher order local autocorrelation (HLAC) features are extracted from the motion history images (MHI). Since MHI calculated from the video images include important motion information, it is expected that HLAC features extracted from MHI have good properties for motion recognition. The proposed features were tested using image sequences of pitching...
Road tracking is a promising technique to increase the efficiency of road mapping. In this paper, a new road tracker, angular texture signature, is proposed based on the knowledge of the roads on high resolution imagery. The tracker uses parabola to model the road trajectory and predict the position of next road centreline point. It employs angular texture signature to get the moving direction of...
