In order to improve the accuracy and real-time of structured road recognition algorithm, this paper puts forward a recognition algorithm of the structural road based on piecewise linear model. Firstly the original image was the initial region of interest division and pretreatment, using an improved Otsu algorithm and mathematical morphology processing image segmentation, eliminate noise and spl...

This paper discusses the importance of confounding in observational before-and-after studies of road safety measures. The importance of the approach taken to controlling for confounding factors is shown by means of examples. It is shown that the size of the effect on accidents attributed to a road safety measure can be profoundly affected by which confounding factors are controlled for in an ev...

A typical way to update map is to compare recent satellite images with existing map data, detect new roads and add them as cartographic entities to the road layer. At present image processing and pattern recognition are not robust enough to automate the image interpretation system feasible. For this reason we have to develop an image interpretation system that rely on human guidance. More impor...

This clinical report describes digital planning and execution using a novel software tool to enhance digital workflow. The proposed treatment, integrated with the face of the patient, was presented before clinical treatment. The patient was rehabilitated with ceramic veneers. The virtual design contributed to a satisfactory and predictable esthetic outcome.

A survey to assess the degree of occupational and physical rehabilitation was conducted on patients treated on chronic haemodialysis, using the semiquantitative Karnovsky scale. The survey revealed that over 90% of patients achieved good rehabilitation and returned to employment or to household duties. Chronic haemodialysis is effective in prolonging life and most patients were rehabilitated wi...
