Computed Tomography Image Edge Degradation Model and its Application to Image Size Measurement
in order to improve the precision of image size measurement
a new arithmetic of size measurement is presented by constructing the approximate function of edge degradation. First this arithmetic constructs the approximate function of edge degradation
and confirms the optimal point of edge detection according to the information of image intensity and inflexions. Then in order to accurately extract the information of image edge
this constructed function is used to revise the primary image; hence the measurement of CT image is accomplished. Excellent results are obtained on the simulation and experiment. This new arithmetic can effectively extract the information of CT image edge,and get an accurate measurement result.
