Trifocal Independent Periodic Lateralized Epileptiform Discharges
Clinical Electroencephalography, 1993The EEG of a 2 1/2-year-old female with a severe cerebral insult showed trifocal periodic lateralized epileptiform discharges (TRIPLEDs). We believe this is the first such record reported. As with BIPLEDs, the physical findings associated with this EEG appear to represent a diffuse cerebral insult. The most frequent causes of BIPLEDs are diffuse anoxic

The trifocal tensor plays an analogous role in three views to that played by the fundamental matrix in two. It encapsulates all the (projective) geometric relations between three views that are independent of scene structure. We begin this chapter with a simple introduction to the main geometric and algebraic properties of the trifocal tensor.

Wide-Angle Trifocal Eyeglasses for Radiologists
Radiology, 1954The advantages of trifocal eyeglasses over bifocals, particularly for presbyopic radiologists, have been explained by Spillman (1). More recently Miles (2) has reported his successful results in providing trifocals instead of bifocals in a group of 50 persons of various occupations.

Constraints for the Trifocal Tensor
2009In this chapter we give an account of two different methods to find constraints for the trifocal tensor Т, used in geometric computer vision. We also show how to single out a set of only eight equations that are generically complete, i.e. for a generic choice of Т, they suffice to decide whether Т is indeed trifocal. Note that eight is minimum possible
