Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0030] In the image recognition scenario, based on active learning and self-supervision, this method proposes a fully automatic learning method for target detection, which solves the cost problem of data labeling and model category migration, and ensures that the model can well adapt to the detection task in practical applications.

[0031] Such as Figure 1-3 Shown, concrete steps of the present invention are:

[0032] 1. Data preparation stage

[0033] Firstly, construct a large-scale original image data set, screen out meaningless pictures through preprocessing, obtain the overall information of the data set, obtain the training set, verification set and test set, divide it into k sets of data, and manually perform a set of data analysis For initial annotation, normalize th...

Abstract

The invention discloses a target detection method based on fully automatic learning. The method includes: using a preprocessed small-scale manual labeling data set, using a deep neural network to train a model, and using a model trained in an Imagenet data set to perform Fine-tune and obtain the depth model; use the depth model to reason and predict the pseudo-labeled part of the original large-scale image dataset, remove the repeated prediction of the same target after non-maximum suppression, and store the bounding box and its confidence of the prediction result by category Degree; Through self-supervised pseudo-labeling and active learning sample selection, jointly learn the information entropy and divergence degree predicted by the deep neural network, sort the unlabeled samples according to the weight, and assign the pseudo-label to the top-ranked high-confidence samples. The purpose of the present invention is to solve the problems of high manpower cost for common target detection and labeling and poor transferability and adaptability of training models in actual scenarios.

Description

technical field [0001] The invention relates to the field of target detection, in particular to a target detection method based on fully automatic learning. Background technique [0002] With the maturity of deep learning and computer vision technology, the use of deep learning to judge the object category, position, and size information contained in the picture—that is, target detection has begun to develop on a large scale. The common target detection workflow is as follows: First, use manually collected image data sets or image data on the network to manually label and construct a data set; secondly, use commonly used target detection algorithms such as Faster-RCNN, YOLO and other training data sets, Get the required model; then, put the model and forward reasoning algorithm on the deployment end or cloud, judge the object category and position contained in the image in the required scene, and get the image information. [0003] However, this workflow has the following p...
