A method and apparatus for characteristic-based video processing include: in response to receiving a region of a picture of a video sequence, determining a characteristic in the region, the region being independent of other regions of the picture for video coding; determining a class associated with the region based on the characteristic, the class being selected from a plurality of classes; and encoding the region using a parameter set associated with the class, the parameter set being selected from a plurality of parameter sets for video coding at different quality levels.

Methods and systems for managing a security system are described. A security server located external to a premises may be in communication with a security system and a gateway device located at the premises. A status signal may be sent to the security server. The status signal may be initiated based on an alarm event. If the security server fails to detect a message of the status signal, the security server may send one or messages indicating the failure.

Techniques for modifying operation of sensors using collected sensor data are provided herein. Sensor data describing a physical environment of a user authorized to access an access-controlled resource is collected according to an initial mode of operation. The initial mode of operation defines an initial performance for at least one sensor used to collect the sensor data. In response to detecting presence of a different user in the physical environment of the authorized user based on the sensor data, the at least one sensor is switched from the initial mode of operation to a modified mode of operation. The modified mode of operation is different than the initial mode of operation and defines a revised performance for the at least one sensor used to collect the sensor data.

A motion detection method includes providing a buffer including a first buffer associated with a background image and a second buffer associated with a foreground image; checking first similarity between the gray level of an input pixel and the first gray level of the first buffer; determining the input pixel as a still pixel if the first similarity is true; checking second similarity between the gray level and the second gray level of the second buffer; determining the input pixel as a moving pixel if the second similarity is false; determining the input pixel as the moving pixel if the second count value is less than the first count value; and determining the input pixel as the still pixel and swapping the first buffer with the second buffer, if the second count value is not less than the first count value.

A video collection system collects and sends metadata related to video data such that recording may be triggered and tagged. The video collection system utilizes a mobile broadband network (such as a cellular network) to send metadata, receive triggers, and perform other functions while the video collection system is in the field. The video collection system broadly comprises a plurality of video cameras and a video collection manager. The video cameras each include a mobile broadband modem or other wireless communication element for sending metadata messages. In some embodiments the mobile broadband modem may also send still images, audio data, and video data.

Method and apparatus for carrying out the method receiving packets, each of the packets comprising a header and a payload. For a particular packet among the packets, the method includes processing at least the header of the particular packet to determine a flow associated with the particular packet; attempting to determine a payload structure based on the flow, the payload structure associated with transport of coded video data in the payload of the particular packet; and if the attempting is successful, repackaging coded video data contained in the payload of the particular packet into a new packet and forwarding the new packet to an external system or storing the new packet in memory.

A method may include transmitting a video stream of a live scene over a network at a real-time transmission speed and detecting an event associated with the video stream being transmitted. The method may include transmitting the video stream over the network at a speed lower than the real-time transmission speed during the event. Transmitting the video stream at the speed lower than the real-time transmission speed may introduce a time stretch for the video stream to be played in slow motion. The method may include reducing a bitrate of the video stream after the event and transmitting the video stream with the reduced bitrate over the network after the event to compensate for the time stretch.

The present technology relates to a control apparatus, a control method, a program, and an electronic device system that enables achievement of low power consumption.

The presence or absence of a preset, predetermined subject is detected from an image having a low resolution output by an image sensor in a low power consumption mode, the image sensor including, as operation modes, the low power consumption mode in which the image having the low resolution is output and a normal mode in which an image having a high resolution as compared with the image having the low resolution is output. Then, in a case where the presence of the predetermined subject is detected, the operation mode of the image sensor is set to the normal mode, and the image sensor outputs the image having the high resolution. The present technology may be applied, for example, to control of the image sensor.

An information output device includes: a first output unit that outputs acquired information acquired by a sensor; and a second output unit that converts personal information included in the acquired information into attribute information from which identification of an individual is impossible, and outputs the attribute information.

The present disclosure relates to a method performed by a background blurring system (1) for provision of a video compression stream from a video camera (2) adapted for capturing a scene. The background blurring system identifies (1001) in a first image of the scene, at a first point in time, at least a first pixel comprised in a background of the first image. The background blurring system further determines (1002) a blurred pixel value for the at least first pixel. Moreover, the background blurring system provides (1003), subsequent the first point in time, the blurred pixel value in the video compression stream. The background blurring system furthermore identifies (1004) in a second image of the scene, at a subsequent second point in time, that the at least first pixel has altered to be comprised in a foreground of the second image. Moreover, the background blurring system provides (1005) in the video compression stream, subsequent the second point in time—continuously and/or intermittently—identified non-blurred pixel values for the at least first pixel. The background blurring system further identifies (1006) in a third image of the scene, at a subsequent third point in time, that the at least first pixel has altered to be comprised in a background of the third image, wherein a value of the at least first pixel has remained unchanged from an intermediate point in time up to the third point in time. Furthermore, when the third point in time is within a predeterminable background merge time period from the intermediate point in time, the background blurring system provides (1007), subsequent the third point in time, the blurred pixel value in the video compression stream.

The disclosure also relates to a background blurring system in accordance with the foregoing, a video camera comprising such a background blurring system, and a respective corresponding computer program product and non-volatile computer readable storage medium.
