  • Original language description

    The open-source software HEXI can detect circles and distinguish between perfect hexagonal ordering and defect configurations. The proposed user-friendly image analysis software (implemented in Python) consists of several stages. First, the algorithm identifies circular structures in microscopy (e.g., scanning electron microscopy, atomic force microscopy) images using the Canny edge detector and the Hough circle transform. Then, the detected circles are categorized as hexagonally ordered or non-hexagonally ordered (defects). This classification can be achieved using three different methods: variance in brightness (global or adaptive) and distance. The software generates visual output (detected coloured circles overlaid over the original image) and quantitative data (total/defective circle count, surface coverage, histogram of size distribution). For more details see: Domonkos et al.,Image analysis algorithm for the verification of hexagonal symmetry in spherical nanostructures, 2022, doi: 10.1016/j.mee.2021.111635.
