Overview
Overview
PlantSpec Quickviewer is a lightweight desktop tool for quick ROI-based multispectral plant image analysis. It helps users inspect aligned RGB previews, define plant regions manually, calculate vegetation and thermal indices, and export publication-ready plots and CSV/XLSX results without using complex remote sensing software.
Plant growth experiments often require repeated steps: organizing multispectral bands, checking plant segmentation, defining regions of interest, calculating indices, and creating figures for reports or manuscripts. PlantSpec Quickviewer combines these steps into one simple GUI.
Users can view an RGB image, preview the plant mask, adjust the threshold, draw ROI boxes or polygons, assign plant names, group names, and sample numbers, and then run the full analysis. The software calculates ExG, NDVI, GNDVI, NDRE, SAVI, OSAVI, CWSI, and temperature in Celsius, then saves group comparison plots and raw data tables.
Key features
Key features
Load multispectral image(or hyperspectral image, but only related to vegetation indices) and generate RGB previews
Preview ExG-based plant masks and adjust segmentation threshold(scroll up and down to find the optimal plant mask)
Draw ROI boxes or polygons directly on the image
Assign custom plant names, group names, and sample numbers
Compare treatment groups such as control vs test
Calculate ROI-level and group-level vegetation indices
Convert thermal raw pixels to Kelvin and Celsius
Calculate CWSI using wet/dry reference scaling
Save stepwise PNGs showing RGB, plant mask, ROI, index maps, CWSI, and temperature maps
Generate matplotlib-based publication-style bar plots
Export CSV and XLSX result tables
Available as a Windows executable and Python source package
when to use it
when to use it
PlantSpec Quickviewer is useful when you need to:
Analyze Micasense Altum-PT (multispectral + Thermal)
Analyze image combination from different device(we can adjust the orientation)
Check experimental image results immediately after or during field experiments
Perform ROI-based vegetation index analysis without GIS or remote sensing software
Analyze only user-selected plots, beds, or plant regions
Produce quick figures and data tables for manuscripts, reports, and lab notes
Provide a beginner-friendly multispectral analysis workflow to non-programmers
It is not intended to replace high-end orthomosaic generation, large-scale geospatial analysis, advanced radiometric calibration workflows, or machine learning classification pipelines. Its main value is fast, field-friendly ROI analysis.
