摘要： A method includes processing a video stream on at least one first camera device to identify actionable motion objects (AMOs). The at least one first camera device or computer system in communication therewith is caused to transmit metadata associated with the identified AMOs to at least one second camera device. A viewing area of the at least one second camera device is dynamically controlled in response to the metadata to enable the at least one second camera device to track and focus on at least one of the identified AMOs.

摘要： Embodiments of methods and apparatus disclosed herein may employ depth, visual, or motions sensors to enable three-dimensional people counting and data mining to enable an energy saving heating, ventilation, and air conditioning (HVAC) control system. Head detection methods based on depth information may assist people counting in order to enable an accurate determination of room occupancy. A pattern of activities of room occupancy may be learned to predict the activity level of a building or its rooms, reducing energy usage and thereby providing a cost savings.

摘要： Systems and methods for transformations between image and map coordinates, such as those associated with a video surveillance system, are described herein. An example of a method described herein includes selecting a reference point within the image with known image coordinates and map coordinates, computing at least one transformation parameter with respect to a location and a height of the camera and the reference point, detecting a target location to be tracked within the image, determining image coordinates of the target location, and computing map coordinates of the target location based on the image coordinates of the target location and the at least one transformation parameter.

摘要： A method of video coding includes receiving a video image having a plurality of pixels, selecting a plurality of Gaussian models for each pixel, classifying each pixel as a background or foreground pixel, determining if an object is always moving locally by detecting if an object is always moving within a predetermined distance and changing the direction of moving frequently for a second predetermined period of time, removing an object from classification as an object and ignoring motion of the object if the object is always moving locally, marking the area that the object moves within as a noisy area on a noise mask buffer, updating background models based on motion detection and noise filtering, updating current and evolving background images, and coding the current background image, background update blocks and objects for transmission.

摘要： Techniques are described for tracking moving objects using a plurality of security cameras. Multiple cameras may capture frames that contain images of a moving object. These images may be processed by the cameras to create metadata associated with the images of the objects. Frames of each camera's video feed and metadata may be transmitted to a host computer system. The host computer system may use the metadata received from each camera to determine whether the moving objects imaged by the cameras represent the same moving object. Based upon properties of the images of the objects described in the metadata received from each camera, the host computer system may select a preferable video feed containing images of the moving object for display to a user.

摘要： An image display method includes: receiving, from a single camera, first and second image information for first and second captured images captured from different perspectives, the first image information having a first data density; selecting a portion of the first captured image for display with a higher level of detail than other portions of the first captured image, the selected portion corresponding to a first area of the first captured image; displaying the selected portion in a first displayed image, using a second data density relative to the selected portion of the first captured image; and displaying another portion of the first captured image, in a second displayed image, using a third data density; where the another portion of the first captured image is other than the selected portion of the first captured image; and where the third data density is lower than the second data density.

摘要： A cloud-based network service provides intelligent access to surveillance camera views across multiple locations and environments. A cloud computing server maintains a database of time periods of interest captured by the cameras connected to the network. The server also maintains defined motion data associated with recorded video content. Video segments are generated from the recorded video content according to both the motion data and the time periods of interest. The server causes the video segments to be transmitted to a user interface, where a user can remotely monitor an environment through the video segments.

摘要： Systems, methods, and devices are disclosed for determining a zooming factor for a camera in a pan, tilt, and zoom (PTZ) camera tracking system to enable a camera to keep an object at a constant size within the camera's viewing area, despite changes in the object's distance from the camera. This provides a complement to a camera's pan and tilt tracking of the moving object. For example, a PTZ camera tracking system that determines an object to track, utilizes information regarding images of the object of interest are used to determine a zooming factor (or other zooming value) for a camera in the PTZ camera tracking system. This information includes variables such as tilt angles of one or more cameras and a reference zooming factor.

摘要： Surveillance systems may be found in both private and public spaces. In private spaces, they can be designed to help provide and monitor secure premises. Similarly, public spaces may also use surveillance systems to determine an allocation of public resources. A camera surveillance system according to an embodiment of the invention uses advanced image processing techniques to determine whether an object moving across a scene is a person. The camera surveillance system achieves an accurate and efficient classification by selectively processing a set of features associated with the object, such as features that define an omega shape. By selectively processing the set of features associated with the object, the methods and systems described herein reduce the computational complexity of standard image processing/object detection techniques.
