The purpose of this theme is to classify sar images into four regions : man - made targets ( vehicles and buildings ), natural targets ( trees and shrubbery ), background ( field and grass ) and shadow ( the target shadow and mirror scatter ). on the one hand, the processed results can be directly used as image product, which offer necessary parameters for expert ' s interpretation to build up an independent auxiliary interpreting system. on the other hand, the results can be introduced into sar image interpreting system as the replacing target detection and discrimination models with layer rois ( region of interest ) in order to provide potential target chips
具體內容為：根據sar圖像基本特性，提取可靠特徵，將圖像區分為人造目標（機動車輛、建築物等） 、自然目標（樹木、灌木、樹林等） 、背景（草地、平地、植被等）和陰影（目標陰影、鏡面散射體等）四種類別，為不同的應用提供對應的感興趣區域（ roi ） 。 -

The land clutter is useless signals for target detection caused by land terrain. the multipath effect is some kind of interference which is caused by wave reflection on terrain. the diffraction effect is the phenomenon of wave propagation into shadow region
地雜波是由地面散射引起的對目標探測無用的信號;多路徑是由電磁波在地面反射所引起的干涉;衍射則是電波繞射傳播到遮蔽區的現象。 -
It is also evident, from area light and its shadow. than that this transition region is smaller next to the shadow casting object and grow larger far away from it
我們也能很清楚地看到這個過渡區域在靠近陰影投射物體物體時較短，遠離時較長。 -
Region - based moving shadow detection approach
基於區域的運動陰影檢測方法 -
Shadow path mark segmentation method based on region - growing for intelligent vehicle
基於區域生長的智能車輛陰影路徑圖像分割方法 -
The light blue region is a partial shadow region where illumination drops smoothly from full light to full shadow
亮藍色區域是一個部分陰影區域，照明從完全照亮柔和地過渡到完全陰影。 -
Shadow detection was performed in every block based on the illumination invariant between the shadow region and the corresponding background region
對其中的每一塊，根據陰影區域和相對應的背景區域之間的光照不變性進行陰影檢測。 -
We partitions the image to three plots, intake area, tracking region, exit region. results from experiments show that the model of hsv adaptive background with shadow detection and extended kalman filter tracking has segmented moving objects and detected shadow so easy and accurately tracked moving vehicles in large area, multiple objects and complex environments. and the system has flexible mathematic model and can meet real - time and practicality requirements
從處理的結果看，本文提出的帶陰影檢測的hsv空間自適應背景模型和卡爾曼濾波運動目標跟蹤模型，易於實現運動物體的分割、及陰影檢測，能比較準確的實現大范圍、多目標的跟蹤，而且數學模型簡單，運算速度快，系統具有很強的魯棒性和實用性，能滿足實時行進車輛的檢測和追蹤的要求。 -

最後，在同樣的成像系統下，研究了物體表面自遮擋陰影對凹陷區的形狀限制，得到了相關的約束條件，並由此實現了一種簡單的凹陷區域重構方法，使簡便的被動式視覺方法有可能重構非凸的復雜形體。 -
This paper presents an algorithm of moving region detection based on chroma, which is able to cope with varying illumination and shadow problems, and refines the detection results with morphology, by marking each moving region in the binary image, the geometrical features parameters such as area, perimeter and form factor can be extracted, which lay the foundation for the analysis and track of moving target
摘要提出了一種基於色度的運動區域檢測演算法，利用像素的色度分量進行檢測，克服了亮度變化和陰影的影響，並利用形態學方法對檢測結果進行后處理，對處理后的運動區域進行標記，提取每個區域的面積、周長、形狀因子等幾何特徵參數，為運動目標後期的分析和跟蹤奠定了基礎。
