Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] See figure 1 , figure 1 It schematically shows the flow chart of the animal head pose estimation method provided by the embodiment of the present invention, and the zebrafish is taken as an example below to introduce in detail. Such as figure 1 As shown, the method includes:

[0035] S1. Carry out target detection processing on the animal picture, and mark the first detection frame of the animal head on the animal picture.

[0036] The purpose of operation S1 is to quickly obtain the zebrafish head region, which is not particularly accurate and probably does not completely cover the zebrafish head. The method used uses a first-order detection neural network to process object detection on a whole zebrafish ima...

Abstract

The invention discloses an animal head posture estimation method and system, and the method comprises the steps: carrying out the target detection of an animal image, and marking a first detection frame of an animal head on the animal image; marking a second detection frame of the animal head according to the first detection frame, and recording position coordinates of the second detection frame,the second detection frame including the whole head of the animal; within the limited range of the second detection frame, performing feature extraction on the animal head to obtain a plurality of keypoint position coordinates corresponding to the animal head; and obtaining the posture of the animal head according to the position coordinates of the second detection frame and the position coordinates of the plurality of key points. According to the method and the system, posture estimation is carried out on the head area instead of the whole picture, so that the calculated amount and the inputinformation redundancy can be effectively reduced, and the accuracy and the speed of zebra fish head attitude estimation are improved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and system for estimating the pose of an animal head. Background technique [0002] Controlling and recording the activity of neurons in the whole brain under the free behavior of animals is of great significance for analyzing the corresponding relationship between animal behavior and brain activity. For example, the zebrafish, whose whole genome is 87% similar to the human genome, is often used to explore the relationship between neuron populations and behavior. In order to carry out optogenetic experiments under the free behavior of animals (zebrafish), it is necessary to estimate the pose of the head image and realize the quantification of the animal's head. [0003] At present, the quantitative methods for zebrafish head mainly include methods based on template matching, methods based on HOG features and methods based on deep learning. [0004] The main idea...
