Optimizing Spectral Binning for PlantEye Products

Posted on 12 February 2025 in , , , by Martijn Houben
Are you looking to improve the accuracy of quantifying symptoms such as chlorosis, yellowing, or necrosis? HortControl offers a key advantage: it quantifies plant areas showing these symptoms based on their spectral values. This process, called “binning,” groups all plant material with a certain spectral value into a “bin,” allowing for precise quantification. For example, one bin can contain all plant tissue showing signs of nutrient deficiency. However, the effectiveness of this method depends on accurately determining the bin thresholds. To support our users, we have developed a Method Note (download below), providing a step-by-step guide to identifying optimal bin-thresholds tailored to your experiment. Case Study: Quantifying Local Nutrient Deficiency Effects in Soybean Plants This Method Note is based on a case study examining nutrient deficiency in soybean plants. Deficiency symptoms appear as yellowing in older leaves and, in severe cases, along the ...
