Abstract

The volume feature point extraction method and device provided by the embodiments of the present invention extract the local contour of the image feature area where the volume feature point is located by establishing an open Snake model with shape estimation. Compared with the traditional Snake model, its extraction The results are more robust and efficient, and can better overcome the influence of the background environment and human clothing on the extraction results, making the extracted local contours more continuous and smooth, meeting the extraction requirements of the final volume feature points.

Description

technical field [0001] The present invention relates to the field of image processing, in particular, to a method and device for extracting volume feature points. Background technique [0002] In image-based non-contact human body parameter measurement, human body contour extraction has a significant impact on measurement accuracy. However, the current traditional Snake model has low efficiency when extracting the complete outline of the human body, and the extraction results are less robust, and are easily affected by the background environment and clothing. Contents of the invention [0003] In view of this, the object of the present invention is to provide a volumetric feature point extraction method and device to improve the above problems. [0004] A preferred embodiment of the present invention provides a method for extracting body feature points, which is applied to image-based non-contact human body parameter measurement. The method includes: [0005] Obtain the ...
