Abstract

The invention provides a sequence image debouncing method and system. The sequence image debouncing method comprises the following steps: S1, segmenting a to-be-processed image sequence; S2, selectingmark points in all cross section image mark areas in each section of image sequence; S3, deleting a jitter point in each section of mark point; S4, fitting the remaining mark points after the jitterpoints are deleted, and fitting an edge curve of the mark area; and S5, translating the image according to the coordinate difference of the mark points before and after fitting, and outputting a sequence image. According to the invention, semi-automatic debouncing of the sequence image is realized, and the image sequence after debouncing conforms to the real state of a human body; Error accumulation is effectively reduced, distortion of a fitted human body image is avoided, manual participation is reduced through a semi-automatic jitter removal mode, efficiency is higher, and the effect is better.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for dejittering sequential images. Background technique [0002] Sagittal plane and coronal plane images are synthesized by cross-sectional sequence images, so the quality of cross-sectional sequence images directly affects the composite quality of sagittal plane and coronal plane, thus affecting its printing quality. In the process of continuous acquisition of cross-sectional images, affected by the instability of the acquisition equipment, the acquired sequence images shake irregularly in the vertical direction, and the synthesized sagittal images are as follows: figure 1 shown. [0003] Effectively removing the irregular jitter of cross-sectional images is a necessary prerequisite for synthesizing high-quality sagittal and coronal images. At present, the main solution is purely manual translation correction one by one, but the disadvantag...
