Abstract

The present invention provides a method and system for image sequence de-jittering, comprising: S1, segmenting the image sequence to be processed; S2, selecting marking points in all cross-sectional image marking areas in each image sequence; S3, Delete the jitter points in each marker point; S4, fit the remaining marker points after deleting the jitter points, and fit the edge curve of the marker area; S5, translate the image according to the coordinate difference of the marker points before and after fitting, and Output sequence images. The invention realizes semi-automatic de-jittering of sequence images, and the de-jittered image sequence conforms to the real state of the human body; effectively reduces error accumulation, avoids distortion of the fitted human body image, and reduces manual labor through the semi-automatic de-jittering method. Participate, be more efficient and more effective.

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...
