Image representation

The cis epoxide is achiral. It is a meso form containing a plane of symmetry. The trans isomer is chiral its two mirror-image representations are not superposable. 

These mirror image representations cannot be made to coincide as long as they are maintained in the plane of the paper. As we have already seen (Sect. 3), such two-dimensionally chiral representations may be taken to depict heterotopic faces. If the sequence is A > B > C, triangle I represents the Re face and triangle II the Si face.

The computer-generated reconstruction in Fig. 19 is consistent with the mercury porosimetry result. The random 3-D network of Fig. 19 contains pore elements up to 3 p.m in diameter. The computer image, however, shows pore features up to 9 p.m in (equivalent) diameter. The imaged representation exhibits these large pore features due to overlapping of pores as the plane section passes close by pore junctions (nodes). A feature may thus contain elements of several pores and thereby appear enlarged in the plane of the section. This aggregation of pore sections is readily discernible in Fig. 19, just as it was in the previous illustrative example in Fig. 16.

A common approach for sparse coding (see for example Lewicki and Sejnowski, 2000) is to use mathematical optimisation to find the best code for signal/image representation. Before coming to the optimisation function, we need to define the norms of a vector.

Hence, the output of color, texture, depth, and motion selective filters form a neuronal image of the perceived scene. Higher level processing uses these attributes to segment the neiu onal image representation [2, p. 251]. This supports the Gestalt...
