Chirality face
All of the known life-forms show specific chiral properties in chemical structures as well as macroscopic anatomy, development and behavior. In any specific organism or evolutionarily related set thereof, individual compounds, organs, or behavior are found in the same single enantiomorphic form. Deviation (having the opposite form) could be found in a small number of chemical compounds, … WebIn this paper, we propose a simple but effective facial feature learning method that takes the advantage of facial chirality to discover the discriminative features for facial expression …

R O R' "Re face" R O … WebEnantiomers are much like one's right and left hands, when looking at the same face, they cannot be superposed onto each other. No amount of reorientation in three spatial dimensions will allow the four unique groups on the chiral carbon (see Chirality (chemistry)) to line up exactly. The number of stereoisomers a molecule has can be determined ...

[1] [2] … WebChirality cues in human faces. By training on the Flickr-Faces-HQ dataset, we also discovered that human faces are especially chiral (i.e., a ResNet model trained to identify whether a random FFHQ face image has been flipped or not could achieve a test accuracy over 80%). Again, we clustered the chirality cues in human faces (as below), and we ...
WebMar 9, 2015 · Prochirality and axial chirality. Prochirality is the idea that a set of achiral groups can give rise to chirality in a reaction. For instance, consider 2-butenone, an achiral molecule. The carbonyl “faces” are said to be enantiotopic. Next, consider propan-2-ol. It is achiral because its two methyl groups are equivalent.
