Problems solved by technology

[0005] When the traditional nearest neighbor algorithm deals with large-scale image analysis problems, the feature dimension of the sample data can reach tens of thousands of dimensions. Such a "dimension disaster" will lead to the problems of large storage space consumption and slow retrieval speed. It is more difficult to analyze one of the images

Abstract

The invention provides a distributed image analysis method and system, and relates to the field of image analysis processing. The distributed image analysis method comprises the steps of obtaining a plurality of candidate images and performing classification marking; determining an index image in the plurality of candidate images and carrying out feature extraction to obtain a feature value; performing similarity comparison on the feature value of the index image and other images in a database, and performing sorting and outputting; and determining a similar image according to the output result, and decoding the similar image to generate an image file. Index images can be selected from a plurality of candidate image sets in a database one by one, feature extraction is carried out on the index images, comparison and sorting are carried out on every two adjacent candidate images, the purpose of distributed image analysis is achieved, and the analysis capacity is improved. In addition, the invention also provides a distributed image analysis system. The system comprises an acquisition module, an extraction module, a similarity comparison module and an output module.

Description

technical field [0001] The present invention relates to the field of image analysis and processing, in particular to a distributed image analysis method and system. Background technique [0002] With the continuous development of social networks, e-commerce, mobile Internet, etc., the scale of data storage and processing is getting larger and larger, and stand-alone systems can no longer meet the growing needs. Internet companies such as Google and Alibaba have successfully spawned the two hot fields of cloud computing and big data. Both cloud computing and big data are applications built on distributed storage. The core of cloud storage is the back-end large-scale distributed storage system. Big data not only needs to store massive amounts of data, but also needs to analyze these data through appropriate frameworks and tools to obtain useful parts. If there is no distributed storage, it will Not to mention the analysis of big data. [0003] Although the research on distri...
