(5) A target image database system has been developed based on SQL Server with the VC++6.0. Accordingly, the technology course and theory model, brought forward in this paper, are validated feasible to manage the target image data.
From software structure and system function, this thesis gives three layers medical image database model and the devices of medical image database from analysis of medical image characters and its functions and tasks.
2 The multi-scale images database of high resolution QuickBird images is builded by using of ortho-images ,and the remote sensing images browsed system of Fu Xin city based on Mapobjets (Its' abbreviation is MO) is setted up .
This paper introduces the characteristics of Orcale Spatial & Intermedia, and gives a detailed description of organization and management of multi-resolution remote sensing image based on Object-Relation Model. The Prototype of multi-resolution remote sensing images database is designed and established based on Oracle. The database adopts tile and image pyramid structure with high-speed index.
Then the aspect ratio and multi-density features were extracted from the text area to select the best candidates from the document image database.
Experimental results on the AR face image database show that the proposed method yields better recognition performance in comparison with the 2DPCA method that is not combined with IMED.
This paper presents a new kind of image retrieval system which obtains the feature vectors of images by estimating their fractal dimension; and at the same time establishes a tree-structure image database.
After preprocessing and feature extracting, a given image is matched with the standard images in the image database using a hierarchical method of image indexing.
We have implemented this technique and tested it in a medical image database of CT images.
