Research on Shape Representation Based on Statistical Features of Centroid-contour Distance

  • 摘要: 該文提出一種新的基于特征統(tǒng)計(jì)的形狀描述方法。通過對(duì)中心-輪廓距離(CCD)和傳統(tǒng)鏈碼(Chaincode)的聯(lián)合統(tǒng)計(jì)分析,使用中心-輪廓距離對(duì)形狀進(jìn)行層次分解,對(duì)各層的形狀映射部分的鏈碼描述進(jìn)行統(tǒng)計(jì)分析,從而形成中心-輪廓距離和鏈碼的聯(lián)合統(tǒng)計(jì)(JSCCDC)描述子。形狀之間的相似性可以用JSCCDC的城區(qū)距離來描述。實(shí)驗(yàn)結(jié)果表明,該表示方法兼具了形狀的全局特征和局部特征,相比于傳統(tǒng)的特征加權(quán)方法具有更優(yōu)越的性能,在形狀匹配和形狀檢索中具有較高的精度和可靠性。
