Embodiment 1

[0035] A method of infrared image object recognition based on deformable convolutional neural network, such as figure 1 shown, including the following steps:

[0036] S1: Collect database samples and set training set and test set. The training set uses COCO. The images in this dataset include 91 types of targets, 328,000 images and 2,500,000 labels. And set the coding of each category in the classifier, for example, the three types of objects car, monkey, and potted plants are coded as 100, 010 and 001 respectively. The test set uses infrared images of substation equipment.

Abstract

The invention discloses a deformable convolutional neural network-based infrared image object identification method. The method comprises the steps of constructing a training set and a test set; establishing a convolutional neural network architecture; adding a softmax classifier to the last layer, and setting an objective function; performing sampling by adopting a convolution kernel of linear ornonlinear deformation; performing pooling operation in a pooling layer by adopting a rule block sampling-based ROI pooling method which is the best in the industry at present; setting learning rate parameters according to experience; and easily performing standard back propagation end-to-end training, thereby obtaining a deformable convolutional neural network. An experiment proves that the spatial geometric deformation learning capability is introduced in the convolutional neural network, so that an identification task of an image with spatial deformation is better finished; the geometric transformation modeling capability of the convolutional neural network and the effectiveness of target detection and visual task identification are improved; and dense geometric deformation in space issuccessfully learnt.

Description

technical field [0001] The present invention relates to the fields of human-computer interaction, computer vision, and object recognition, and more specifically, to an infrared image object recognition method based on a deformable convolutional neural network. Background technique [0002] Body recognition is a very important research field in computer vision, including face recognition, handwritten digit recognition, gesture recognition and object recognition, etc. It can be widely used in human-computer interaction, image classification and image retrieval and other fields. The two main indicators to measure the quality of an object recognition system are: recognition rate and recognition speed. Generally speaking, a higher recognition rate means a relatively slow recognition speed, and a faster recognition speed means a relatively low recognition rate. Therefore, how to weigh the pros and cons has always been an unavoidable problem in the field of object recognition. ...
