This paper presents a survey of image processing techniques proposed in the literature forextracting key cereal crop growth metrics from high spatial resolution, typically proximalimages. The descriptive crop growth metrics considered are: crop canopy cover, aboveground biomass, leaf area index (including green area index), chlorophyll content, andgrowth stage. The paper includes an overview of relevant fundamental image processingtechniques including camera types, colour spaces, colour indexes, and image segmentation. The descriptive crop growth metrics are defined. Reference methods for groundtruth measurement are described. Image processing methods for metric estimation aredescribed in detail. The performance of the methods is reviewed and compared. The surveyreveals limitations in image processing techniques for cereal crop monitoring such as lackof robustness to lighting conditions, camera position, and self-obstruction. Directions forfuture research to improve performance are identified.

目的评价自体荧光检测诊断黄斑裂孔的效果。方法应用自体荧光检测黄斑裂孔。对黄斑裂孔、手术修补术的患者(组1)和作为对照的黄斑假洞或黄斑皱褶的患者(组2),分别行眼底荧光血管造影、自体荧光检测、眼底彩照、无赤光和红外摄像检查,进行回顾性研究。其中自体荧光采用132型Heidelberg眼球探针,对所得到的9个图象进行平均处理。而所有患者手术前后都进行OCTIII检测。结果10个术前被自体荧光检测发现的黄斑裂孔均由OCT确诊,而且所有病例的自体荧光信号均与黄斑裂孔相对应。自体荧光也可应用于术后,以评价裂孔的闭合程度。在OCT确诊裂孔闭合的所有患者以及对照组10例黄斑皱褶或假洞患者,均没有发现自体荧光。对照组均由OCT证实,没有黄斑裂孔的发生。结论自体荧光检测是诊断黄斑裂孔的一个新方法,它同时能够检测术后黄斑裂孔的封闭效果,没有自体荧光则表明裂孔已封闭。
