Retraction Note to: Cultural changes in coral community based on image segmentation and travel public service in coastal areas

Abstract

The threshold separation method is an image segmentation technique that is divided into several types according to the gradation value. It is a classification method based on image histogram segmentation. The purpose of the image threshold is to divide the entire pixel into a region having similar properties according to the gradation level. Each area after separation will match the real object, and each area will have the same internal properties, and this property is different from the surrounding area. The coral reef ecosystem consists of various components, such as coral groups, algae, boom, fish and microorganisms, and non-biological components, which forms a connection with each other. Coral biological communities are one of the largest varieties and the most abundant community in the marine environment. The defined coastal area refers to the region of the coastline and is divided into three levels according to the administrative region: province, city and district. The coastal area of the first line is mainly located in coastal provinces, and autonomous regions. The tourism public service system is not a new research topic. Instead, tourism public services have been conducted in the government, academia and tourism. This paper mainly analyzes the relevant theoretical concepts and public service tourism systems on public service tourism under the premise of intelligent information and tourism.
