Purpose: To establish a two dimensional gel electrophoresis image analysis method for analyzing the differentially expressed proteins between SHEE and SHEEC. Methods: The whole soluble proteins of SHEE and SHEEC were extracted by one step and separated using 2 DE. Different expressions of the whole soluble proteins were analyzed using the 2 DE image analysis software, PDQuest 6.2(Bio Rad Inc). Results: After the background subtraction, spot detection and matching, the protein spots which expressed differentially...

Purpose: To establish a two dimensional gel electrophoresis image analysis method for analyzing the differentially expressed proteins between SHEE and SHEEC. Methods: The whole soluble proteins of SHEE and SHEEC were extracted by one step and separated using 2 DE. Different expressions of the whole soluble proteins were analyzed using the 2 DE image analysis software, PDQuest 6.2(Bio Rad Inc). Results: After the background subtraction, spot detection and matching, the protein spots which expressed differentially were obtained. Seven protein spots were detected in SHEE, and two protein spots were seen in SHEEC but not in SHEE. Conclusion: The 2 DE results of two intimate biosytems were analyzed quickly and efficiently using PDQuest 6.2 gel image analysis software.

A novel motion detection algorithm which employs adaptive background su btraction and symmetrical differencing is presented in this paper. A modified se lective updating model is proposed as the reliable adaptive background updating method, and we combine the background subtraction with symmetrical differencing to detect the motion information. After the motion detection operation, morpholo gic filtering and connected region area measurement are introduced to suppress t he noise and solve the background disturbance problem. Then the area filling alg orithm is used to fill the small hole in the detected object. Finally the moving objects are extracted reliably. The result of the experiment demonstrates that the pres ented algorithm runs quickly and veraciously.
