A new edge detection operator based on dual parity morphological gradients is proposed. in order to accurately segment a porcelain insulator string in an infrared image before the identification and diagnosis of deteriorated insulators by the extracted thermal information. When applied to the double-shed insulators. the proposed detector is capable of effectively eliminating the blurr... https://www.inmuebleslasmercedes.com/product-category/knife-sharpening-steels/
