Research On Digital Photo Annotation System

At the turn of the 21 st century,with the advent and popularization of digital cameras,we are ushering in the digital era of images.The preservation of old paper photos is no longer suitable for today.Digitizing photo files has become the trend,and we need to establish new For image preservation and retrieval methods,the photo files are analyzed and researched under the digital age technology framework,and the digitized files need to be stored and managed by establishing an image database.These digitized images not only present the image information on the surface,but can also record a lot of invisible information.These information are attached to the digital image information system as a label and become an important reference basis for defining the image.Photographs are a kind of WYSIWYG image carrier.When it is given a definition,it can be used as an empirical material for people to study.It can also play an important role in supporting the digitized historical images.In the past,based on the limitations of film and photos,a lot of photo information can only be built on film bags or cards.Therefore,we need to start from the digitization of photos and establish an effective management program based on the subject of photography.The digital image information is effectively regulated and defined,and the seemingly disordered image information is grouped into an orderly,satisfactory,and easy-to-retrieval information chain.These digital information chains constitute the historical writing in the digital era with images as empirical evidence.,Established a perfect photo information system,thereby enhancing the empirical nature of photos.This article takes the digital era as the background,builds an orderly searchable and visible front and back information system under the framework of the image database according to the characteristics of digital technology,and combines relevant practical cases to sort out some important image materials saved in the past.And annotation,through this move to explore the value behind the photo,with the ultimate goal of entering the image history database,try to explore the question of the authenticity and reliability of the photo by many scholars in the 20 th century.
