3. researching on the edge detection method of surface image. after using the edge detection operator for the preliminary abstracting, a series of extending work, such as grey bivalence 、 thinning 、 noise reduction and compagination have been done
3 .對帶鋼表面圖像的邊緣檢測方法進行了研究及實現，採用邊緣檢測運算元對邊緣初步提取，進行了二值化、細化、去噪聲、連接等一系列后續處理工作，並且較好的判斷了邊緣是否良好的情況。 -
The depositional character of zhuxiang formation in the basin reads as follows : a series of nne alluvial fan were formed along the fault. the half - deep lake to deep lake faces appeared by west side of the fault, towards the west the saucer lake faces, shore deposit and flood plain face appeared in proper order. the depositional center of lower cretaceous was formed in eastern part of the basin, and the depositional depth was pinch - out and thinning out from the east to the west
盆地內下白堊統朱巷組沉積特徵表現為：沿郯廬斷裂帶呈北北東向廣泛發育了沖積扇體系，從近斷裂帶西側出現的半深湖-深湖相，向西依次為濱淺湖相到泛濫平原相的規律性分佈，沉積厚度由東向西尖滅、超覆，構成了明顯的東斷西超的盆地構造格局，表明下白堊統的沉積中心依然位於盆地東部。 -
In this paper, the part of apis based on minutia features includes mainly computing orientation, filtering, binarization, thinning, feature extraction, postprocessing and minutia matching ; the part of apis based on statistical features is composed of reference point location, extracting feature, classification and matching. some new approaches are brought forward : 1 ) in the preprocessing, a new binarization method of fingerprint images based on the orientation and the dynamic threshold is proposed, which has the excellent capability of noise resistance. this method makes fully use of the orientation and the characteristics of grayscale change, gets the binarized images from the primitive fingerprint images directly, instead of the series of processing such as smoothing, enhancement and binarization
本論文對這兩種系統做了深入地研究，從基於細節點特徵的系統中求取指紋方向圖? ?濾波? ?二值化? ?細化? ?特徵提取? ?后處理，到基於統計性特徵的系統中選取指紋圖像參考點? ?提取統計性特徵? ?分類? ?匹配等環節，都一一進行了討論，並提出了一些新方法： 1 ）在基於細節點特徵系統的預處理部分，本論文提出一種新的基於方向圖具有動態閾值的指紋圖像二值化方法，這種演算法能夠在保持特徵點不丟失的基礎上一次性完成一般指紋圖像處理中的無效塊分割、增強、濾波、二值化的過程。
