提出了一种改进基于形状的图像检索的质量和查询时间的方法。我们定义了一种新颖而准确的形状描述符--距离内部比(DIR),它对刚体运动和尺度是不变的。形状的DIR也可以存储在高效的搜索结构中。实验结果表明,该方法具有较高的检索率和较高的查询时间。
We propose a method to improve the quality and the query time of shape-based image retrieval. We define a novel and an accurate shape descriptor namedDistance Interior Ratio (DIR)that is invariant to rigid motion and scaling. The DIR of shapes can also be stored in an efficient search structure. Our experimental result shows a higher retrieval rate and efficient query time.
