Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the examples, but the embodiments of the present invention are not limited thereto.

[0033] Such as figure 1 As shown, the bird image recognition method based on head part alignment of the present embodiment includes the following steps:

[0034] S1 training process:

[0035] S1.1 Collect images of various birds to form a training data set; this embodiment selects a data set of 200 types of birds from the California Institute of Technology. This data set contains image data of 200 different types of birds, and each category has 300 images. above;

[0036] S1.2 Manually select the head area of ​​each bird in the training data set, and divide the head of each bird image in the training data set into right, left and middle postures;

[0037] S1.3 For the bird images with the bird's head facing left or right in the training data set, that is, the bird image of the lateral posture, perfor...

Abstract

The invention discloses a bird image identification method based on head part alignment. The method comprises steps of: aligning the head positions of bird image data with various orientations after the positions of parts are predicted; enabling the aligned bird images to be subjected to feature extraction and classifier training so that an optimum classification plane among various bird images is obtained and a criterion is provided for subsequent bird observation images. The alignment of the head parts of the bird images solves posture influences in bird image classification. Further, the method does not need to accurately position the parts and just predict the rough appearance area of each part so as to achieve high precision and low difficulty.

Description

technical field [0001] The invention relates to the technical field of recognition, in particular to a bird image recognition method based on alignment of head parts. Background technique [0002] At present, there are some literatures on bird recognition, but the literature on bird image recognition has not been found. In terms of bird identification, patent 2009102108999 provides a remote wireless monitoring system based on audio-visual integrated wild bird identification technology, which is used for remote ecological monitoring. The system includes a song recording module, a video recording module, and audio and video data processing. module, audio and video stream transmission module and audio and video digital file storage module. Patent 2013105810072 provides a mobile bird recognition method based on birdsong. The present invention preprocesses the bird's song signal collected by LabVIEW software, and processes the bird's song signal after the pretreatment by the AO...
