WebIntroduction. This web site is a resource for students and professionals interested in the microstructure of cement based materials. We have gathered images from our own … WebAutomated microscopy typically relies on autofocusing used for the analysis of information content behaviour along the z‐axis within each field of view. However, in the case of a field of view containing more objects that do not lie precisely in one z‐plane, traditional autofocusing methods fail due to their principle of operation. WebThe autofocusing strategy, therefore, becomes a main consideration for the image quality in the WSI system (6,7). To address the autofocusing challenge, many WSI systems create a focus map prior to the scanning process. For each focus point on the map, the system will scan the sample to different axial positions and acquire a z-stack. jefferson county courthouse parking
