【摘要】：对舞蹈技术动作与音乐进行合理匹配,可提高舞台和音乐的契合度。进行舞蹈技术动作与音乐匹配时,应得到多个长度较短的动作-音乐片段组合,对每步获得的节拍预测位置进行节拍对齐,计算出舞蹈动作-音乐片段之间的相关性系数,但是传统方法通过获取音乐和舞蹈底层的风格底层特征,并提取音乐舞蹈底层特征进行相关性分析去除冗余特征对完成匹配,但是不能对动作-音乐片段组合进行提取,无法进行节拍对齐和舞蹈动作-音乐系数计算,导致匹配舞蹈动作与音乐变化同步性较差。提出一种基于蚁群理论的舞蹈技术动作与音乐匹配优化方法。上述方法先融合于音乐节拍提取理论对同步的舞蹈动作和音乐数据进行分划,得到多个长度较短的动作-音乐片段组合,对音乐片段进行突变点检测,对每步获得的节拍预测位置进行节拍对齐,计算出舞蹈动作-音乐片段之间的相关性系数,得到舞蹈动作匹配优化目标函数,结合蚁群理论对目标函数进行优化求解,将音乐编舞中全部音乐-舞蹈动作片段按照信息素浓度自适应调整信息素挥发因子,依据舞蹈动作匹配优化解的优劣性动态更新信息素,由此完成舞蹈技术动作与音乐匹配优化。仿真结果表明,所提方法能够充分体现音乐与动作变化的同步性,并且优化的舞蹈动作匹配方法匹配的音乐-舞蹈匹配质量较优。
[Abstract]:The match between dance technique and music can improve the compatibility between stage and music. When matching dance technique with music, we should get several short combination of action and music segment, align the predicted position of each step, and calculate the correlation coefficient between dance action and music segment. But the traditional method can get the bottom features of music and dance, and extract the bottom features of music and dance for correlation analysis, and remove redundant features to complete the matching, but can not extract the combination of action and music segments. It is impossible to calculate the beat alignment and the dance motion-music coefficient, which leads to the poor synchronism between the matching dance movement and the music change. In this paper, an ant colony theory based optimization method for matching movement and music in dance technology is proposed. First, the method is combined with the music rhythm extraction theory to divide the synchronized dance movements from the music data, and obtain a number of short length motion-music segment combinations to detect the mutation point of the music segment. The beat prediction position of each step is aligned, the correlation coefficient between dance action and music segment is calculated, the optimization objective function of dance action matching is obtained, and the objective function is optimized by combining ant colony theory. According to the pheromone concentration, all the music-dance action segments in music choreography are adjusted adaptively to the pheromone volatilization factor, and the pheromone is dynamically updated according to the optimal solution of dance action matching. Thus, the matching optimization of dance technique action and music is completed. The simulation results show that the proposed method can fully reflect the synchronism of music and movement changes, and the matching quality of the optimized dance motion matching method is better than that of the music dance matching method.
