摘要： Systems and methods are provided for determining a depth map and a reflectivity map from a structured light image. The depth map can be determined by capturing the structured light image and then using a triangulation method to determine a depth map based on the dots in the captured structured light image. The reflectivity map can be determined based on the depth map and based on performing additional analysis of the dots in the captured structured light image.

摘要： The present invention provides a speech enhancing method for communication earphone including two parts: sending end noise reduction processing and receiving end noise reduction processing, wherein the sending end noise reduction processing part includes: determining a wearing condition of the earphone by comparing energy difference of sound signals picked up by microphones of the communication earphone; if the earphone is normally worn, subjecting the sound signal first to multi-microphone noise reduction and then to single channel noise reduction to further suppress residuary stationary noise; otherwise suppressing stationary noise in the sound signal by single channel noise reduction directly.

摘要： Methods, devices and computer program products facilitate conditional access to a content embedded with watermarks. For such a content, when copy control rules associated with an embedded watermark message prohibits unconditional access to the content, it is determined whether or not an exception to the copy control rules exists, and if an exception to the copy control rules exists, the content is conditionally accessed. Additional watermark messages can be extracted while the content is being conditionally accessed, and based on the additionally extracted watermark messages, it is verified that conditional access to the content has been fulfilled.

摘要： Methods, devices, and computer program products facilitate the application of a content use policy based on watermarks that are embedded in a content. Watermark extraction and content screening operations, which can include the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted at different times by different devices. These operations can be conducted by one or more trusted devices that reside in a networked environment. The authenticity of various devices can be verified through the exchange of certificates that can further enable such devices to ascertain capabilities of one another. Based on the ascertained capabilities, an operational configuration for conducting watermark extraction and content screening can be determined.

摘要： Techniques for protecting the security of digital representations and of analog forms made from them, including a technique for authenticating an analog form produced from the digital representation, an active watermark that contains program code that may be executed when the watermark is read, and a watermark agent that reads watermarks and sends messages with information concerning the digital representations that contain the watermarks. A watermark agent may be a permanent resident of a node in a network or of a device or it may move from one network node to another. The watermark agent executes code which examines digital representations residing in the node or device for watermarked digital representations that are of interest to the watermark agent. The watermark agent then sends messages which report the results of its examination of the digital representations. If the watermarks are active, the agent and the active watermark may cooperate.
