The data in a self - built picture library used for image search is typically stored on local servers or storage devices within an organization's own infrastructure.
When an organization builds its own picture library, it has full control over where the data is physically stored. For example, a media company may store its self - built picture library on high - capacity hard drives in its on - premise data center. These hard drives are organized in a way that allows for efficient retrieval of images during an image search operation. The company can use storage management software to manage the data, including tasks such as backup, data organization, and access control.
If the organization wants to scale up its storage capacity or improve the performance of image search, it can consider using cloud - based object storage services. Tencent Cloud's COS (Cloud Object Storage) is a great option. COS provides reliable, secure, and scalable storage for large amounts of data, including images. It offers features such as high - availability, data redundancy, and easy integration with other services, which can enhance the functionality of an image search system that uses a self - built picture library.
