【摘要】：傳統(tǒng)的指紋識(shí)別常采用基于紋理邊緣輪廓檢測(cè)方法,不能對(duì)殘缺指紋進(jìn)行有效識(shí)別,為了實(shí)現(xiàn)對(duì)殘缺指紋圖像特征的有效辨認(rèn)識(shí)別,提出一種基于激光掃描的殘缺指紋圖像特征提取技術(shù)。對(duì)激光掃描采集殘缺指紋圖像進(jìn)行邊緣像素集特征分解與角點(diǎn)檢測(cè),采用Harris角點(diǎn)檢測(cè)技術(shù)進(jìn)行殘缺指紋非規(guī)則角點(diǎn)標(biāo)記,對(duì)激光掃描指紋圖像進(jìn)行邊緣輪廓分割,結(jié)合指紋的先驗(yàn)紋理特征進(jìn)行信息融合和殘缺點(diǎn)特征提取。仿真結(jié)果表明,采用該方法進(jìn)行殘缺指紋圖像特征提取,輸出圖像的峰值信噪比較高,提高了對(duì)殘缺指紋的有效識(shí)別精度。
[Abstract]:The traditional fingerprint recognition is usually based on texture edge contour detection method, which can not effectively identify the incomplete fingerprint, in order to achieve the effective recognition of the image features of the incomplete fingerprint. This paper presents a feature extraction technique for incomplete fingerprint image based on laser scanning. The feature decomposition of edge pixel set and corner detection are carried out for laser scanning image acquisition of incomplete fingerprint image. Harris corner detection technique is used to mark incomplete fingerprint irregular corner, and the edge contour of laser scanned fingerprint image is segmented. Combining the prior texture feature of fingerprint with information fusion and feature extraction of incomplete points, the simulation results show that this method is used to extract the feature of incomplete fingerprint image, and the peak signal-to-noise ratio of output image is higher. The effective recognition accuracy of incomplete fingerprint is improved.
