Abstract: Healing by growth of epithelium over a denuded surface is observed by wound assessment process .This study involves the measurement of the amount of wound healing which is done by the simple digital image (taken by SLR digital camera)analysis of particular wound. More than 10 cases are observed with proper skin grafting. Reliability of this assessment process was verified by finding the class of digital image along with interclass correlation .Normally a digital image is a 2-D raster image ,which is not containing depth information .This approach is to design a algorithm to detect the detailed process of wound contraction process by modeling a 3D structure . The simple digital image is first determined and grouped by the class of the image following the edge detection and information of pixel to pixel is grouped. Grouping is feasible by choosing the same colour and same spatial placement of the pixel matrix. Pixel to pixel depth dependency is mapped with a matrix using digital image processing toolbox in Matlab. Finally bilateral filtering and rendering will show the 3D contraction model of wound. In conclusion wound epithelization and contraction is a completed process which can be assessed by clinician .This process will help clinicians to detect the amount of healing by producing quantitative measurements. It can be easily compared and studied for different degree and types of wound .Nano silver are used to heal the wound. The wounds are assumed as a denuded surface. The action of nano silver over that surface area is designed as a meshed skin graft integrated with the effect of nano silver crystalline material.
