RESUMO
Fluorescent image of human mucous can display a special color to demonstrate a cancer at its early stage. This will provide a novel method for early diagnose of the Pathological Changes. This research firstly extracted the color characteristics of the clinic images and then calculated all RGB components in different local areas. Finally, a stability analysis was performed. On the above basis we showed a conclusion that G/R can be used as a judge index for pathologic changes.

Localization system was designed based on analytic equation of permanent magnetic field to localize the swallowing electrical capsule in the gastrointestinal. Algorithm was presented and experiment was made. Two three-axis magnetism sensors were mounted in the capsule. The non linear equations set of sensor's output and capsule's position and attitude was created according to space position and attitude relationship model. The equations set was resolved with numerical method. Comparison between the calculation value and expected value showed that this method was feasible.
