Quantitative visibility assessment of silver nanowire based transparent spatial heaters for defogging and defrosting

The demand for efficient transparent heaters with defogging and defrosting capabilities has driven significant research into advanced materials and their performance evaluation. This paper presents an effective method for quantifying visibility based on image processing techniques. By employing computational algorithms, we objectively analyze visibility from images, offering a more precise and reproducible assessment than conventional subjective evaluations. This approach is applied to evaluate the performance of silver nanowire (Ag-NW) based transparent heaters for defogging and defrosting. The proposed visibility quantification method established a robust, reliable and standardized framework for performance evaluation and analysis of various optical, optoelectronic, architectural and automotive materials and devices.
