AI总结:

针对多光谱图像光谱带冗余问题,提出纳入噪声、滤波器带宽等预设条件的最优滤波器选择方法,可降冗余、降成本,在SMM数据集上大幅减少误分类数。

摘要:

使用多光谱相机阵列采集图像在医疗、农业和环境领域的应用日益重要。然而,使用所有可用光谱带不仅不可行,还会产生大量数据,而给定任务仅需其中一小部分。相邻波段可能包含相似信息,因此评估过程中不应考虑冗余光谱带,以保持较低的复杂度和数据负载。现有方法会选择数量受限且预先确定的光谱带。我们的方法通过纳入预设条件(如噪声或可用滤波器的带宽)改进了这一流程,最大程度降低了光谱冗余。此外,还可进行最小化滤波器选择,在保持硬件设置低成本的同时,仍能获取所有重要的光谱信息。与快速二分搜索滤波波段选择方法相比,我们使用随机森林分类器,将SMM数据集的误分类目标数量从318个减少到124个。

英文摘要:

Capturing images using multispectral camera arrays has gained importance in medical, agricultural and environmental processes. However, using all available spectral bands is infeasible and produces much data, while only a fraction is needed for a given task. Nearby bands may contain similar information, therefore redundant spectral bands should not be considered in the evaluation process to keep complexity and the data load low. In current methods, a restricted and pre-determined number of spectral bands is selected. Our approach improves this procedure by including preset conditions such as noise or the bandwidth of available filters, minimizing spectral redundancy. Furthermore, a minimal filter selection can be conducted, keeping the hardware setup at low costs, while still obtaining all important spectral information. In comparison to the fast binary search filter band selection method, we managed to reduce the amount of misclassified objects of the SMM dataset from 318 to 124 using a random forest classifier.
