peer agreement (net): +1reflectivity(reflectance) curve analysis Explanation: 光谱反射率曲线;spectral reflectance curve 性质：被物体反射的光通量与入射到物体的光通量之比即光反射比与波长之间的关系曲线。一种物体的光谱反射率曲线反映了该物体对入射光的光谱选择性吸收、光散射以及物体表面的镜面反射的综合特性。是颜色测量、色差计算评比、电脑配色等色度计算的基础。 Graphical analysis of spectral reflectance curve The nature of GASC algorithm is to find out spectral invariant that will help to easily classify land cover objects according to their spectral reflectance characteristics. This method assumes that different land cover objects has different spectral reflectance pattern. This pattern should be stable for certain remote sensing senor with fixed observation spectral channel composition. The six 250m spectral channels of GLI sensor are equivalent to six channels of well known LANDSAT TM sensor excluding the thermal one. Given a pixel vector.

scan reflectance profile (SRP) grading (method)/scan reflectance profile analysis Explanation: If this grading method has been designed based on GB/T 18348, then 反射率曲线 here should mean "scan reflectance profile (SRP)", which is a method to determine bar code print quality as used in ISO 15416. Scan Reflectance Profile (SRP): The record of the reflectance values (0%-100%) measured along a single line across the entire width of the bar code symbol. http://www.swinglabels.com/glossary/glossary.asp You may refer to the Chinese specification of GB/T 18348 for an idea: 扫描反射率曲线 ｓｃａｎ ｒｅｆｌｅｃｔａｎｃｅ ｐｒｏｆｉｌｅ 沿扫描路径，反射率随线性距离变化的关系曲线，见图１ http://209.85.175.104/search?q=cache:6ALKBv1uvtQJ:tiaoma.123... You may also refer to this ISO guideline: http://72.14.235.104/search?q=cache:kbn_e8d3mWQJ:www.lvs-inc... The ISO Print Quality Guideline recommends a method of measuring the quality parameters of a printed bar code symbol. In order to grade the eight individual parameters associated with ISO, a Scan Reflectance Profile (SRP) is generated mapping out the reflectance characteristics of an entire bar code symbol. The lowest grade received by any individual ISO parameter becomes the overall ISO grade for that Scan Reflectance Profile. Ten scan grades are required to calculate the overall grade of a bar code symbol. These ten grades are then averaged to determine the final ISO grade for the symbol. Several SRP parameters are employed in this method to calculate an overall grade for the SRP. |
