In order to perform the recommendation between different types of multimedia data . recommendation of music pieces from human motions the proposed method tries to estimate their relationship. Specifically the correlation based on kernel CCA is calculated as the relationship in our method. Since human motions and music pieces have various time lengths it is necessary to calculate the correlation between time series having different lengths. Therefore new kernel functions for human motions and music pieces which can provide similarities between data that have different time lengths are introduced into the calculation of the kernel CCA-based correlation. This approach effectively provides a solution to the conventional problem of not being able to calculate the correlation from multimedia data that have various time lengths. Therefore the proposed method can perform accurate recommendation of best matched music pieces according to a target human motion from the obtained correlation. Experimental results are shown to verify the performance of the proposed method.
