A Method for Editing Human Body Pose in Images

Abstract

The invention discloses a human body posture editing method in an image. The human body posture editing method comprises following steps of: firstly, adopting an image segmentation method to calculate a human body silhouette and an image background in the image; secondly, adopting a silhouette profile projection method to obtain original shape parameters of a human body by use of original posture parameters of the human body obtained through calculation by using a model optimization-based human body posture identification method; thirdly, adopting a sketching interaction method to edit the original posture parameters and shape parameters so as to obtain edited posture parameters and the shape parameters; fourthly, adopting an image shape change method based on the least square method to generate a new silhouette; and finally, adopting an image synthesis method based on textures to generated an edited image. By use of the human body posture editing method, edition of human body postures in the image can be realized, the human body posture editing method is advantaged by simple operation, real effects and the like, is capable of effectively overcoming problems of inconsistent overall situations and warped backgrounds existing in a traditional image editing tool and has a wide application prospect in the field of plane design, multimedia manufacturing, computer cartoons and the like.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a human body posture editing method in an image. Background technique [0002] Using professional image editing tools such as Photoshop, etc., users can easily edit images, but such tools can only complete some low-level editing tasks, such as modifying skin spots and wrinkles. For high-level editing tasks such as human body posture editing, it is difficult to maintain global consistency during the editing process, and even skilled operators need to spend a lot of effort to achieve it. However, human body posture editing in images has important applications in graphic design, multimedia production, computer animation and other fields, and its potential application value makes image editing an important topic in the field of computer image processing research. [0003] How to maintain the global consistency in the editing process of human body pose and improve the oper...

Problems solved by technology

However, this method requires manual labeling of human body joints, and uses motion capture data as input for pose editing, which does not provide an effective means of interactive pose editing.

At the same time, the shape control is realized through the camera perspective projection model, which cannot meet the user's needs for human body shape editing

[0006] To sum up, the current research on image editing methods mainly focuses on visual effect processing, such as tone adjustment, image denoising, etc. The editing of the human body also focuses on the editing of the shape of the human body, but there is no interaction design, editing effect, etc. for the editing of the human body pose.
