To resolve the difficulty of defect segmentation in variable grey image, the image processing based on Visual Basic programming method was adopted. The methods of automatic contrast and partial grey stretch were used to enhance the X-ray detection image which has relatively low contrast, then automatic threshold method was carried out to segment the two high intensity zones, and weld zones which contain the small defects was extracted. Smoothing and sharpen processing were proceeded on the extracted weld zones, and small defects in X-ray detection image of weldments with complex structure were segmented by using the method of background subtraction in the end. The effects of raster were eliminated, and because of that the image processing was only proceeded on the extracted weld zones, the calculated speed using the above provided algorithm was improved.展开更多

But presentation of messages that reach and resonate with the intended audience remains challenging. This is due in part to the variety of mindsets—viewpoints, attitudes, and beliefs—within a population. These mindsets play an essential role in understanding and predicting behaviors and lifestyle factors associated with health or chronic diseases. The purpose of this study is to demonstrate how a specific survey-based method of mindset segmentation can distinguish predominant mindsets and then be used to create, adapt, and/or market health programs to appeal to these mindsets. Steps in survey construction, distribution, and analysis are described. Interpretation of the results, yielding three primary mindsets, is the critical outcome of this segmentation method. The applications of this interpretation to community health education programs are suggested. This approach has potential to inform, enhance, or customize programs, tailoring activities, methods, and messages to the preferences of the community.展开更多
