Abstract

The invention discloses an image recognition method and a device, which relate to the technical field of detection and recognition. In order to solve the problem in the prior art that the accuracy ofimage recognition decreases when the distribution of the training set and the test set differs greatly, the image recognition method includes: acquiring a sample image (101); determining a priori probability distribution (102) of each category image occurring in a current scene; and recognizing the sample image according to a priori probability distribution to obtain a recognition result (103). The method is applied in the process of image recognition.

Description

technical field [0001] The present application relates to the technical field of detection and recognition, and in particular to an image recognition method and device. Background technique [0002] With the development of image recognition technology, the deep convolutional neural network (English: Convolutional Neural Network, CNN) algorithm has gradually become the mainstream algorithm in the research and application of image recognition such as image classification and object detection. [0003] Taking image classification as an example, before the test process, it is often necessary to carry out deep neural network training for the existing image classification model, and optimize the solution on the training set (English: training set) to minimize the global loss (English: loss) . Later in the test process, the soft maximization layer (English: softmax layer), which is the output layer of the deep convolutional neural network, will assign a confidence level to each ca...
