摘要 针对多媒体图像形状检索,提出增强型曲率尺度空间(ECSS)描述子,构建了基于该描述子的形状检索模块IRS.通过直接计算曲率,减少卷积计算次数进行特征抽取,从而显著减少了运算量;设计实现了镜像变换等匹配策略,使IRS检索的结果更符合相似性要求. In order to retrieve multimedia image, we proposed Enhanced Curvature Scale Space(ECSS) and designed ECSS-based shape retrieval module IRS. ECSS extracts the features by computing the curvature directly,which greatly reduces the computation of convolution. We also take mirror transform into account and the retrieval result of IRS looks more similar.
