  • Publication number: 20180173956
    Abstract: A method for identifying events in a scene captured by a motion video camera comprises two identification processes, a temporary identification process and a long-term identification process. The temporary process includes: analyzing pixel data from captured image frames and identifying events; registering camera processing data relating to each image frame subjected to the identification of events; and adjusting weights belonging to an event identifying operation, wherein the weights are adjusted for achieving high correlation between the result from the event identifying operation and the result from the identification based on analysis of pixels from captured image frames of the captured scene. The long-term identification process includes: identifying events in the captured scene by inputting registered camera processing data to the event identifying operation.

  • Publication number: 20180174414
    Abstract: A method, system, and computer program product of encoding a digital image comprising a privacy mask. Information representative of pixels in the digital image is received. The pixels are grouped into encoding units. Information representative of a privacy mask area in which a privacy mask is to be applied on the image is also received. All encoding units that at least partially are located within the privacy mask area are identified, and the privacy mask area is extended to be aligned with the identified encoding units. For each encoding unit, a respective quantization parameter to be used for encoding the image is determined. The privacy mask is applied in the extended privacy mask area of the image, and the image with the applied privacy mask is encoded using the determined quantization parameters. The digital image encoding system may be included in a camera.
