On the basis of thinning the auto - body film engineering drawings, a self adaptive precision vectorization algorithm for circles on the auto - body engineering drawings was presented
摘要在車身薄膜圖掃描圖像細化的基礎上，提出一種自適應精確向量化圖的演算法。 -
Its main steps are : 1 median filter to filter yawp ; 2 edge detecting ; 3 figure thinning ; 4 the calculation of center point and some other parameters, we put forward a new method with which we firstly give a self - adjust liner transform then we use robert edge detecting and we also give an four - adjacent - field method for edge thinning here ; secondly we repeat four steps above and use the center point as focus in the fourth image. after this we track the forecasting center point by kaveman filter and select two blocks for locating. lastly from the fifth photo on we mainly deal with the arithmetic for matching locating and recognition of focus except kaveman filter
然後在第四幅圖像中：重復上述四步，以提取的形心為瞄準點，在選定瞄準點以後，為了在後續圖像中匹配、定位、識別瞄準點，我們使用卡爾曼濾波求取跟蹤預測的形心點並在瞄準點的周圍選取兩個匹配定位塊：從第五幅圖像開始，除了使用卡爾曼濾波求取跟蹤預測形心點以外，主要執行匹配、定位、識別瞄準點的演算法。 -
In this dissertation, a combinatorial algorithm based on the directional segmentation is proposed for the preprocessing of the fingerprint images, this combinatorial algorithm is composed of normalization, directional image computation, directional filtering ( gabor filtering ), local self - adaptive binarization, noise elimination and thinning
本文的預處理演算法包括以下步驟:規一化、方向圖計算、方向濾波（採用gabor濾波） 、局部自適應二值化、二值化去噪和細化。 -
Seed collection should begin when seed on the most top of the spike sloughing, and go on for 3 days. biology population of this plant was research on clone and modular level, mainly discussed how density affect the population size and biomass, as well as the " - 3 / 2 self thinning " and the primary productions under different densities
從無性系構件和個體水平上進行了野大麥種群生物學方面的研究。主要討論了密度對種群數量和生物量的影響，對「 - 3 2 」自疏法則進行了討論，並從草地生產角度比較了不同密度種植區的草地凈第一性生產力。
