Genre Classification of Traditional Malay Music Using Spectrogram Correlation

A method to classify the genre of traditional Malay music using spectrogram correlation is described. The method can be divided into three distinct parts consisting of spectrogram construction that retains the most salient feature of the music, template construction that takes into account the variations in music within a genre as well as the music progresses, and template matching based on spectrogram image cross-correlation with unconstrained minimum average correlation energy filters. Experiments conducted with seven genres of traditional Malay music show that the recognition accuracy is dependent on the number of segments used to construct the filter templates, which in turn is related to the length of music segment used. Despite using a small dataset, an average recognition rate of 61.8 percent was obtained for music segments lasting 180 seconds using six relatively short excerpts.

Fusion of License Plate and Face Recognition for Secure Parking

Integration of multimodal biometrics is widely explored for the purpose of security enhancement. Hence, in this research we deemed further to evaluate the integration of car plate and face recognition as security enhancement in parking lot. Firstly, the acquired face and car plate that acted as database is encrypted based on Hill Cipher matrix manipulation using random numbers and Fast Fourier Transform (FFT) as encryption algorithm. Next, Unconstrained Minimum Average Correlation Energy (UMACE) was applied for car plate recognition process during parking entrance in identifying the intruder via Peak to Side lobe Ratio (PSR) value. During exit, UMACE is once again utilized for both plate and face recognition for verification of registered driver based on decision fusion of PSR value. Results attained specifically Total Success Rate (TSR) of 96% during parking entrance along with over 99% during exit at PSR value of 10, confirmed that the proposed method is apt as security in parking space.
