Abstract

The invention discloses a visualized management and retrieval method for a digital image. The method comprises the following steps: establishing a binary bitmap sequence for the digital image by a digital image processing technological system and extracting a plurality of feature primitives from the sequence (the primitives refer to factors in the image which are different from pixels, such as a line segment, a curve, a closed figure, texture and the like); correspondingly extracting RGB, a gray value and other data of pixels in the peripheral range of relevant positions from the original digital image according to the position range of the primitives, extracting a set of texture elements according to the texture range related to the primitives, and indexing the digital image according to a plurality of the primitives, the set of the texture elements and corresponding pixel values; and storing the digital image and the image indexing, relevant text comment, network link analysis and the like for retrieving the digital image. In the invention, indexing of the digital image is established based on the binary bitmap sequence, the primitives, the texture elements, the pixels and the like, thus achieving small data quantity and fast and convenient retrieval and being applicable to digital image management, retrieval and search for a mobile communication network and the Internet.

Description

Technical field [0001] The invention discloses a method for visually managing and retrieving digital images. Especially the index of digital image of the present invention is based on binary bitmap, primitive (primitive, refers to the element that is different from pixel in the image, as line segment, curve, closed figure etc.), texel and pixel foundation, index digital image is accurate , with small data volume and fast network retrieval, it is suitable for mobile communication network and Internet digital image search, management and retrieval. [0002] The digital image visualization of the present invention is based on the application of graphics and imaging techniques in computational science, focusing on the use of computer graphics to create visual images, thereby helping people understand those complex and Digital images in the form of large-scale digital representations are often used in digital image acquisition, analysis, indexing, calculation, classification, stor...
