Abstract: A host may provide a crowd-source price program. Participants in the crowd-source price program are incentivized to participate by rewards offered by the host. A participant acquires commercial information related to goods, services, or both being offered by a merchant and provides the host with the commercial information. The commercial information may include a purchase price for goods, services, or both being offered by the merchant and may include an identifier corresponding to the goods, the services, or both. The host may validate the commercial information, generate a reward, and provide the reward to the participant. The reward may be an offer for goods, services, or both offered by the host. The participant may accept the reward.

Abstract: An imaging system includes an optical unit that captures, from a scene, sets of first images as well as sets of second images. The scene is illuminated with non-structured light when the sets of first images are captured and illuminated with structured light when the sets of second images are captured. A pattern processing unit generates, from the second images, a recovered shadow pattern from a shadow pattern projected onto the scene during illumination with structured light, wherein at least one motion-compensated reference image is used. A depth processing unit obtains depth information on the basis of the recovered shadow pattern.
