    • The present invention provides a system and a method for extracting musical note sequence from a musical signal by incorporating music theory and instrument knowledge. The method includes receiving a replica of a musical signal, identifying musical notes and instrument frequency envelopes of the musical signal by means of spectral analysis and an adaptive knowledgebase, generating a subtractive signal based on the musical notes and instrument frequency envelopes, and subtracting the subtractive signal from the replica of the musical signal. The note-sequence extracted from music signals is used to mine a music database significantly improving search and similarity calculation. The method of present invention provides printable musical score of the musical signal which includes staff and tablature notations with beamed notes, dynamic marks, ornaments, velocity marks and accidentals.
    • 本发明提供了一种通过结合音乐理论和乐器知识从音乐信号中提取音符序列的系统和方法。 该方法包括接收音乐信号的复制品,通过频谱分析和自适应知识库识别音乐信号的音符和乐器频率包络,基于音符和乐器频率包络生成相减信号,并将该相减 来自音乐信号复制品的信号。 从音乐信号中提取的音符序列用于挖掘音乐数据库,显着改善搜索和相似度计算。 本发明的方法提供了音乐信号的可打印乐谱,其包括带有横向音符,动态标记,装饰物,速度标记和偶然事件的工作人员和制表符记符号。

    • [0061] A system and method for local deformable motion analysis and for accurately tracking motion of an object isolating local motion of an object from global motion of an object is disclosed. The object is viewed in an image sequence and image regions are sampled to identify object image regions and background image regions. The motion of at least one of the identified background image regions is estimated to identify those background image regions affected by global motion. Motion from multiple background image regions are combined to measure the global motion in that image frame. The measured global motion in the object image regions are compensated to measure local motion of the object and the local motion of the object is tracked. A system and method for accurately measuring the local deformable motion of an object as the relative motion between two control point sets is disclosed. The point sets are defined as the inner contour and the outer contour of an object. The motion of the control point sets is estimated and the relative motion is used to characterize the local deformation and local motion of the object
