Embodiment Construction
[0055] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0056] figure 1 As shown, it is a flowchart of an image key point extraction method provided according to an embodiment of the present disclosure, such as figure 1 As shown, the method includes:
[0057] In S11, first feature maps corresponding to human body parts in multiple resolutions in the target image are extracted.
[0058] Among them, feature extraction can be performed according to the Resnet network. When performing feature extraction based on the Resnet network, multiple resolutions can be preset. For example, the multiple resolutions may be resolutions corresponding to 1 / 4, 1 / 8, 1 / 16, 1 / 32, etc. of the resolution of the image input to the Resnet...

The invention relates to an image key point extraction method and apparatus, a readable storage medium and an electronic device. The method comprises the steps of extracting a first feature map corresponding to a human body part under multiple resolutions in a target image; inputting each first feature map into an extraction model corresponding to the resolution of the first feature map to obtainkey point features corresponding to each first feature map; Decoding the key point features to obtain image segmentation features corresponding to the first feature map, the image segmentation features being used for indicating human body parts; and determining key points of the human body part in the target image according to the image segmentation characteristics and the key point characteristics corresponding to the first characteristic patterns. Therefore, the accuracy of extracted features can be effectively improved, and an accurate data basis is provided for extracting key points; The region corresponding to the key point of the human body part in the target image can be effectively determined, and the human body key point extraction efficiency and accuracy are improved.
Description
technical field [0001] The present disclosure relates to the field of image processing, and in particular, to an image key point extraction method, device, readable storage medium and electronic equipment. Background technique [0002] The development of computer technology promotes the development of image processing technology. In the prior art, the most important part of image processing is to extract the key points of the image, so that subsequent processing or operations can be performed based on the key points of the image. For example, when estimating the pose of a human body part in an image, feature extraction is usually performed on the image, and then key points of the image are directly determined according to the extracted features. However, through the above solution, the error of the determined key points of the image is too large, which affects the subsequent processing. Contents of the invention [0003] The purpose of the present disclosure is to provid...
