Analyzes of temperature and light characteristics for drip irrigation under plastic film cotton canopy at blossoming and boll - forming stages 膜下滴灌條件下棉花花鈴期冠層內(nèi)的溫光特征分析
First , this dissertation gives a geometrical projection - based 3d warp algorithm , which has proved the feasibility to bring the studying method of ibr into geometry models - based modeling and rendering . it is an all - purpose algorithm , which can perform coordinate warping under different projection for scene and object models , and , this algorithm can perform color warping according to lighting characteristics 算法的提出證明了將圖像繪制的研究方法引入幾何繪制領(lǐng)域的可行性,算法通用性好,對(duì)場景模型與對(duì)象模型均能夠依據(jù)不同的投影關(guān)系進(jìn)行圖像的坐標(biāo)變換,同時(shí),算法還能夠依據(jù)光照特性對(duì)象素點(diǎn)顏色值進(jìn)行變換。
We adopt the latest gray scale image correction technology and preset abundant adjusting parameters according to x - ray image demand , thus the corrected roc curve accords with the film ; its light characteristic totally meets dicom . image layer is rich , natural and detailed , and the phenomenon of black edge is basically eliminated 采用最新的灰階影像調(diào)校技術(shù),針對(duì)xray的圖像要求預(yù)設(shè)了豐富的調(diào)節(jié)參數(shù),能夠使圖像質(zhì)量高層次豐富自然細(xì)節(jié)完整,基本消除了一般圖像增強(qiáng)中的黑邊現(xiàn)象。
