Abstract

The invention relates to an ultraviolet discharge image segmentation method and a computer readable medium, and the method comprises the steps: 1, obtaining a to-be-segmented ultraviolet discharge image, and carrying out the preprocessing of the image; step 2, carrying out superpixel segmentation on the ultraviolet image; step 3, performing saliency detection on the image; and 4, performing binarization threshold selection on the saliency detection result by using an Otsu algorithm optimized by a bat algorithm with Levy flight characteristics to obtain an ultraviolet image segmentation result. Compared with the prior art, the method has the advantages of good segmentation effect, accuracy, rapidness and the like.

Description

technical field [0001] The invention relates to the technical field of image segmentation, in particular to an ultraviolet discharge image segmentation method combined with saliency detection and Otsu algorithm optimization and a computer-readable medium. Background technique [0002] When problems such as insulation aging occur in power equipment, partial discharge may exist, which affects the safe and stable operation of the equipment. The light emitted by partial discharges includes visible light, infrared and ultraviolet light. Traditional detection methods include artificial visual and infrared imaging, etc., but when these two methods detect visible light or infrared signals, the power equipment is often severely damaged and generates heat, the timeliness is poor, and they are easily interfered by sunlight. The effect is not ideal. The wavelength of ultraviolet rays irradiated by the sun on the earth is above 280nm, and the interval below 280nm is called the solar bl...
