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.

阈值分离法是一种根据灰度值分为几种类型的图像分割技术。它是一种基于图像直方图分割的分类方法。图像阈值的目的是根据灰度等级将整个像素划分为具有相似属性的区域。分离后的每个区域都会与真实物体匹配，并且每个区域都会具有相同的内部属性，并且该属性与周围区域不同。珊瑚礁生态系统由珊瑚群、藻类、繁荣、鱼类和微生物等各种成分与非生物成分组成，相互联系。珊瑚生物群落是海洋环境中最大的品种和最丰富的群落之一。所界定的沿海地区是指海岸线区域，按行政区域划分为省、市、区三级。一线沿海地区主要分布在沿海省区。旅游公共服务体系并不是一个新的研究课题。相反，旅游公共服务已经在政府、学术界和旅游业进行。本文主要分析了智能信息和旅游前提下公共服务旅游的相关理论概念和公共服务旅游体系。旅游公共服务体系并不是一个新的研究课题。相反，旅游公共服务已经在政府、学术界和旅游业进行。本文主要分析了智能信息和旅游前提下公共服务旅游的相关理论概念和公共服务旅游体系。旅游公共服务体系并不是一个新的研究课题。相反，旅游公共服务已经在政府、学术界和旅游业进行。本文主要分析了智能信息和旅游前提下公共服务旅游的相关理论概念和公共服务旅游体系。
