项目摘要

In order to develop a system in which online handwritten symbols can be utilized efficiently, I have studied the following two subjects. First I propose a method to improve the personal character classifiers which am learned from examples by using the virtual examples synthesized from on-line characters written by a particular user. To obtain the good classifiers, usually a large database which contains enough number of variations of handwritten characters is required. In this study, I have proposed a method to train SVM for character recognition based on the artificially augmented examples using on-line characters written by a particular user A virtual example is synthesized from an on-line character by applying Sae transformation to each stroke. SVM classifiers am trained by using the artificially generated patterns. The effectiveness of the proposed method was examined by experiments of handwritten Japanese Hiragana character classification Second, to make it easier for a novice composer to produce a piece of music, a method which expands a user-entered music using an existing music database, has been proposed. The outline of the procedure is as follows: 1. in the database, the most similar part is found by comparison between the urer-entered music and all parts of the database based on their pitch sequences, 2 using linear regression model, a transformation matrix between the retrieved music and the user-entered music, is calculated, 3. new music can be produced by applying the transformation with the calculated matrix to the parts before and after the retrieved music, and 4. the produced music am added to the parts before and after the user-entered music. In my experiments, we composed several Owes of music with the use of a database which consists of twelve pieces of music. As a result, it was confirmed that the tool could produce comfortable music.
为了开发一个系统,其中在线手写符号可以有效地利用,我研究了以下两个主题。首先,我提出了一种方法来改善个人字符分类器,这是从例子中学习,通过使用虚拟的例子合成从一个特定的用户写的在线字符。为了获得好的分类器,通常需要一个包含足够数量的手写字符变体的大型数据库。在这项研究中,我提出了一种方法来训练SVM的字符识别的基础上,人工增强的例子,使用在线字符由一个特定的用户写一个虚拟的例子合成从一个在线字符通过应用Sae变换到每个笔画。通过使用人工生成的模式来训练SVM分类器。通过手写体日文平假名字符分类实验验证了该方法的有效性。第二,为了使新手作曲家更容易制作一首音乐,提出了一种使用现有音乐数据库扩展用户输入的音乐的方法。该程序的概要如下:1.在数据库中,通过在用户输入的音乐和数据库的所有部分之间基于它们的音高序列进行比较,找到最相似的部分; 2使用线性回归模型,计算检索到的音乐和用户输入的音乐之间的变换矩阵;可以通过将具有所计算的矩阵的变换应用于所检索的音乐之前和之后的部分来产生新的音乐;以及4.所产生的音乐被添加到用户输入的音乐之前和之后的部分。在我的实验中,我们使用一个由12首音乐组成的数据库来创作几首音乐。结果证实,该工具可以产生舒适的音乐。
