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 recognition method based on the alignment of head components. First, after predicting the position of the components, the head position alignment is performed on bird image data in various orientations; the aligned bird images are extracted by corresponding images Features and classifier training and learning, so as to finally obtain the best classification plane among various bird images, and provide discrimination basis for subsequent bird observation images. Since the present invention is based on the alignment processing of bird image head parts, it solves the influence of posture factors in bird image classification, and at the same time, the method of the present invention does not need to accurately locate the position of the parts, but simply predicts the approximate 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...
