Unlike a typical pyramid, which has four triangular sides and one square or rectangular base, a tetrahedron has only three triangular sides and a triangular base. In other words, a tetrahedron has four faces, all of which are triangular in shape but are not necessarily congruent. Each face ca...
The effect of image pyramid Image pyramid for multi- scale training and testing helps improving the detection per- formance, as shown by "Baseline+Pyramid" in Table 1. By applying our strategies we observe another improvement ("Final+Pyramid"). We follow the same way in [26] to build the...

The tetrahedronis the three-dimensional case of the more general concept of a Euclidean simplex, and may thus also be called a 3-simplex. The tetrahedron is one kind of pyramid, which is a polyhedron with a flat polygon base and triangular faces connecting the base to a common point. ...
