Abstract

The invention relates to the field of image processing and discloses a quick clustering preprocessing method for massive image eigenvectors. The method comprises the following steps of (A) two-stage thread pool processing; and (B) two-stage Map storage structure processing. A two-stage thread pool comprises a primary preprocessing thread pool which performs simple pre-clustering, and a secondary combination thread pool which performs secondary clustering combination; and in a two-stage Map storage structure, a large clustering result Map is divided into sub-Maps, and combination and comparison operations of the sub-Maps are carried out in parallel. The method has the beneficial effects that a clustering operation process is suitable for running in a multi-core server through the two-stage scheduling design; and through the two-stage Map storage structure, the influence of blockage between clustering comparison and clustering update tends to 0.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a fast clustering preprocessing method in massive image feature vectors. . Background technique [0002] In the field of intelligent image analysis, the early steps of image analysis generally include structured processing of images. After the structured processing process operates on the pixel matrix data of the image (such as using a neural network model), a limited-dimensional image is finally obtained. A high-dimensional vector is used to express the characteristics of the original image. This vector is generally also called the feature vector of the image, and the image feature vector is the type of input data. [0003] In the intelligent analysis of images, there are two basic problems. One is to solve the classification problem of "what" the image is (such as face detection), and the other is to solve the "who is the image individual in the known set of certain types of th...
