A solid electrolytic capacitor of the invention includes a metal electrode employing a metal, a dielectric layer formed on a surface of the metal electrode and composed of an oxide of the metal, and a carbon material layer overlaid on the dielectric layer. In a film implementation, because film is a sequence of frames, using information from neighboring frames may enable a temporally smoother visual experience. An insert member is fit within an opening in the cage member. The system fluid reservoir is pressurized at a substantially constant back pressure, with a pressurizing gas, preferably helium, that suppresses in-gassing, and that is substantially insoluble to the system liquid. Furthermore, the present techniques are effective when the number of relevant object attributes are large and no specialized classification hardware is accessible.
