High-quality insulator region proposals play important roles in the process of transmission line inspection images. A generation method of insulator region proposals based on edge boxes is proposed in this paper, and edge boxes are applied to the localization of insulators in inspection images creatively. We take a series of operations to generate insulator region proposals: K-means cluster is used...
Wavelet threshold de-noising method is an important approach for image de-noising. In the paper, the standard deviation estimation of image noise was introduced, and its correction was given. Based on its correction, a wavelet shrinkage threshold method of image de-noising was proposed. The principle of wavelet image de-noising was discussed. The standard deviation of image noise was estimated by...
