Ultrafast holographic topometry of the face for medical applications

Improvements in Shape-From-Focus for Holographic Reconstructions With Regard to Focus Operators, Neighborhood-Size, and Height Value Interpolation

“…12). A typical digitization of a human face is done with a lateral resolution of 100 m and an intertomogram distance of 500 m. Details on the experimental realization can be found in [5], [12], and [14].…”

“…1 shows exemplarily one image from the focus series and a screenshot of the resulting, textured 3-D computer model of the face. Such highly resolved textured 3-D models of living human faces are of great interest in many kinds of applications, among others in medicine and forensic science [8]- [14].…”

Three‐dimensional reconstructions of solid surfaces using conventional microscopes

“…The improvements of the software correlate with some of the achievements in the SFF literature of the last twenty years (e.g. in: Nayar and Nakagawa, ; Niederost et al ., ; Thelen, ; Thelen et al ., ; Thelen et al ., ). The software has been also rearranged to yield graphical outputs resembling that accompanying the confocal microscope Olympus OLS 3100, which was used in our studies (Ficker, ; Ficker et al ., 2010, ; Ficker and Martišek, ).…”

“…The software employed in the present study is capable of automatically increasing the pixel windows when a threshold criterion is not fulfilled at a given point. The criterion is based on the height difference between the profile maximum and the noise level (Thelen, ; Thelen et al ., ). When this height difference is lower than a defined value, the pixel window is extended and the profile is calculated for the new window.…”
