Abstract: Input video frames are encoded into a sequence of output video frames arranged in groups of pictures (GOP). Each input video frame is encoded into an output video frame using a respective compression value. Each GOP in the sequence of output video frames has a GOP length defined by a number of frames contained in the GOP. A level of motion and a level of light in a first input video frame are determined. If level of light is below a predetermined threshold value, encode the first input video frame using a predetermined constant GOP length and a compression value which is a decreasing function of the level of light. If level of light is above, encode the first input video frame using a GOP length which is a decreasing function of the level of motion, and a compression value which is a decreasing function of the level of light.

Abstract: There is provided a method for controlling an infrared cut, IR-cut, filter of a video camera. An indication to switch state of the IR-cut filter of the video camera is received, and a switch of state of the IR-cut filter is synchronized with a video encoding of frames captured by the video camera, such that the IR-cut filter is controlled to switch state when the video camera is about to capture a frame which is a predetermined number of frames before a frame which is scheduled to be encoded as an intra-frame.

Abstract: A method and system for finding services in a service-oriented architecture network may include receiving, in a local service registry from a client, a search query for a particular service. The local service registry may include a local database listing registered services.

Abstract: A method and system for tracking objects in a defined area compares image data of a detected object to profiles of persons that have entered the defined area to find the best match and connect the profile of the best match to the detected object. Identification profiles of persons that have been identified, by presenting their credentials, when entering the defined area are registered as candidates and are later matched with objects detected in the defined area. The system and method use the physical access control system of the defined area to reduce the number of candidates for the detected objects to the most likely candidates. The processing time and need for resources of the object tracking in the defined area are thereby reduced.
