Feature distribution method and device, electronic equipment and computer readable storage medium

Abstract

The invention relates to a feature distribution method and device, electronic equipment and a computer readable storage medium, N image features and attribute information corresponding to each image feature are acquired from a to-be-distributed image feature library at a certain period T, and the attribute information comprises an object identifier used for indicating an object to which the image feature belongs; according to the attribute information, de-weighting processing is carried out on the N image features, latest image features corresponding to the object identifiers are reserved, and de-weighting image features are obtained; the de-duplicated image features are saved into a barrel to be distributed in a memory; and the de-duplicated image features are taken from the to-be-distributed barrel, and the de-duplicated image features are allocated to a plurality of distribution channels for parallel distribution. And errors caused by disorder of subsequent image feature processing sequence can be avoided.

Description

technical field [0001] The present application belongs to the field of image processing, and specifically relates to a feature distribution method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] After each picture is extracted from the image feature, an image feature is obtained. In the application process of image features, it is often necessary to obtain a large number of image features, and distribute the image features to the receiving end through the thread channel, so that the receiving end can perform feature comparison based on image features in the subsequent processing. [0003] An image feature has its corresponding object, and an object may correspond to multiple image features. In order to improve the comparison accuracy and efficiency when the receiving end performs feature comparison based on image features, it is usually desirable to use an image feature of the same object for comparison, and this image feat...

Problems solved by technology

Due to differences in processing speed and processing pressure of different thread channels, it may cause the image feature 1 generated earlier to reach the receiving end, and the image feature 2 generated later to arrive at the receiving end first, resulting in the old image feature 1 covering the new one. The case of image feature 2

In order to avoid this situation, it is necessary not only to judge whether the image feature corresponding to the same object as the image feature exists in the receiving end, but also to further judge the image when there is an image feature corresponding to the same object in the receiving end. The order of generation time of feature 2 and image feature 1 will greatly reduce the efficiency of image feature distribution

In another case, if image feature 1 is distributed to the receiving end by thread A, but image feature 2 has been distributed to the receiving end by thread B but has not yet been written, the receiving end may think that the receiving end has not saved any corresponding image feature 1 The image feature of the object, so the receiving end allows image feature 1 to be written, so that the receiving end saves image feature 1 and image feature 2 at the same time, resulting in duplication of image features saved by the receiving end
