This bias mainly come from the un - uniform characteristics of the system and the couplings between the receiving channels. if we use fourier transformation to retrieve the image, the errors introduced by this bias will not be represented
如果使用理想的傅立葉方法反演亮溫圖像將反映不出系統的不理想因素,而且因為這些誤差對于可視度函數值的影響不同,一一剔除是極其困難的。Taking erectophile type continuous vegetation as a example, authors had done many monte carlo simulations, and established empirical analytic expressions of radiances with component temperature, soil emissivity and leaf area index. empirical analytic expressions were used to construct objective function and genetic algorithm was employed to synchronously retrieve 5 parameters, such as component temperature, soil emissivity and lai, from thermal infrared 2 channels and 2 angles data. many experiments of genetic algorithm inversion from simulated data were conducted, results show that it is very robust to retrieve component temperature using genetic algorithm ; genetic algorithm can cope with uncertainty inversion problem pretty well if full advantage of priori knowledge was taken. comparison between inversion results and ground - truth data has been done. this paper offers a new example to retrieve component temperature from multi - channel, multi - angle thermal infrared data based on the model of directionality of thermal radiance
在熱輻射方向性規律的基礎上,以喜直型連續植被為例,進行了大量的monte carlo模擬,建立了輻射亮度和組分溫度植被葉面積指數及土壤比輻射率之間的經驗函數關系。採用遺傳演算法,從熱紅外2個波段2個角度數據中,同時反演混合像元組分溫度土壤比輻射率和葉面積指數等5個參數。通過對模擬的觀測數據進行大量的遺傳演算法反演試驗,結果表明,遺傳演算法反演組分溫度非常穩健,在寬松的先驗知識條件下,遺傳演算法可以解決不確定性反演問題。Secondly, the paper emphasizes particularly on introducing two different approaches to brightness temperature ( for short, tb ) of layered medium. one is based on rt theory ( called rt method ), and the other is on the basis of dgf ( called dgf method ). according to the methods, the relational expressions between tb of two - layer medium and the thickness of its first layer ( for short, thickness ) are achieved respectively
接著,著重介紹分層媒質亮度溫度(即亮溫)的兩種不同解法:基於rt理論的亮溫求解法( rt方法)和利用並矢格林函數的特點得到亮溫的方法( dgf方法) ,並推導出不同溫度分佈情況下,雙層媒質的亮溫隨第一層厚度的變化關系;結果表明:在相同溫度分佈情況下,兩種方法所得亮溫隨厚度的變化趨勢相同,但rt方法所得亮溫與厚度間是? ?對應關系,而dgf方法則不是。Automatic threshold choice is difficult and important to color images edge detection, first of all, on the base of human visual properties, threshold versus intensity function of human visual system are researched and analyzed, by using method of mathematic modeling and the result of saturation research, function of least color difference that can be perceptible by visual systems in detecting edge is given
摘要自動閥值選取是彩色圖像邊緣檢測的難點和關鍵問題,首先從人類的視覺特性出發,分析了人類視覺系統的亮度感知門限函數,利用數學建模方法和色度學方面的研究成果,給出人類視覺系統對彩色圖像邊緣所能識別的最小彩色差函數。The range of a large range of brightnesses will be emitted by the flames, and so you will need to use the exposure function to bring them within range of your monitor
