Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Natural scenes are usually complex and changeable. For image target counting tasks, it is easily affected by various factors, such as severe occlusion between targets, target deformation, uneven distribution of targets, messy background interference, distortion of camera perspective, etc. . In particular, the influence of the perspective effect of the camera makes the size of the same object vary in different depths of the scene, and the cam...

Abstract

The invention discloses an image object counting method based on a convolutional neural network. The image object counting method makes the characteristics learned by the network robust to the targetdeformation through a robust enhancement layer, and lowers the computational complexity of the model; a pyramid layered counting module is used to perform density estimation, and the multi-scale information contained in hierarchical features of the convolutional neural network are fully used, which significantly improves the computational efficiency while accurate counting is achieved. In summary,the image object counting method is based on the convolutional neural network, achieves accurate counting of the target in an image, and can be applied to a target counting task in a complex scene, and is low in computational complexity and high in practical application value.

Description
