Reflective polarization valve engine and projection display are disclosed. Instead of prism PBS, the projector applies wire-grid polarizers with advantages of higher heat-resistance, no limitation of the incident angle and no birefringence effects, to provide excellent contrast luminance. The light source in the projector utilizes an elliptical lamp under a telecentric optical system to achieve higher efficiency and avoid color gradient. In addition, the light paths are in special arrangement. The original beam is first splitted into RGB, and then proceeding with color-recombining right after being polarized via wire-grid polarizers and analyzed by reflective polarization valves. Hence, the analyzed beams finally are recombined images with superior performances.

A sentiment visualization system provides a method for identifying content sentiment visually, and does so in a way that is also relevant to individuals who are colorblind. The system provides multiple visual cues that identify sentiment. In some embodiments, the visualization shows a bar that displays a color gradient. The color gradient is anchored by a positive color on one end and a negative color on the other end. The bar contains a color-neutral notch that represents where the sentiment value lies. The system may also allow a viewing user to reclassify an automatically determined sentiment of an item, such as by dragging a notch or other control on the visual display to a new location. Thus, the sentiment visualization system allows users to quickly sift through a large amount of content and identify high priority items for which a fast response is warranted.

A system and method for determining the location of human faces within a color graphics image is disclosed.
