Abstract: A method and device for communicating video for synchronization between a portable wearable camera and a wireless hub device are described. The portable wearable camera may capture first video data. Also, the portable wearable camera may transmit the first video data to the wireless hub device via a video data channel, and may capture second video data. When the video data channel between the wearable camera and the wireless hub device is unable to support full resolution video playback, the portable wearable camera may store the second video data. Further, the portable wearable camera may receive a request via a control channel, from the wireless hub device, for the second video data, and may capture third video data. Further, the portable wearable camera may transmit, to the wireless hub device, the third video data via the video data channel and the second video data via the control channel.

Abstract: A method for detecting an object in a first distorted image using a sliding window algorithm, comprising: receiving an inverse of a mathematical representation of a distortion of the first distorted image; wherein the detection of an object comprises sliding a sliding window over the first distorted image, the sliding window comprising a feature detection pattern, and for each position of a plurality of positions in the first distorted image: transforming the sliding window based on the inverse of the mathematical representation of the distortion at the position, wherein the step of transforming the sliding window comprises transforming the feature detection pattern of the sliding window such that a resulting distortion of the feature detection pattern of the transformed sliding window corresponds to the distortion of the first distorted image at the position; and using the transformed sliding window comprising the transformed feature detection pattern in the sliding window algorithm.

Abstract: A device and a method of signing an encoded video sequence comprising: obtaining an encoded video sequence composed of encoded image frames; generating a set of one of more frame fingerprints for each encoded image frame; generating a document comprising a header of a supplemental information unit, and a representation of the generated sets of one or more frame fingerprints; generating a document signature by digitally signing the document; generating the supplemental information unit to only consist of the document, the document signature and an indication of an end of the supplemental information unit; and signing the encoded video sequence by associating the generated supplemental information unit with the encoded video sequence.

Abstract: Storing and retrieving media recordings in an object comprises a first method of storing a media recording comprising the following steps performed at an ingest component of a system: assigning a recording ID to the media recording; storing media data in one or more data objects in an object store, each carrying the recording ID; storing media metadata in an attribute object carrying the recording ID; computing a hash of the metadata; and storing the hash, the recording ID, a recording interval and a recording source in an index object. The first method further comprises concatenating the index object with an existing index object using a maintenance component. A second method is suitable for retrieving a media recording stored in an object store using the first method. A third method is suitable for performing maintenance on the object store by concatenating specific groups of index objects.

Abstract: A method for determining whether or not a transparent protective cover of a video camera comprising a lens-based optical imaging system is partly covered by a foreign object is disclosed. The method comprises:
obtaining (402) a first captured image frame captured by the video camera with a first depth of field;
obtaining (404) a second captured image frame captured by the video camera with a second depth of field which differs from the first depth of field; and
determining (406) whether or not the protective cover is partly covered by the foreign object by analysing whether or not the first and second captured image frames are affected by presence of the foreign object on the protective cover such that the difference between the first depth of field and the second depth of field results in a difference in a luminance pattern of corresponding pixels of a first image frame and a second image frame. The first image frame is based on the first captured image frame and the second image frame is based on the second captured image frame.-

Abstract: A method for suppressing chromatic aberration, especially blue or red fringing, in a digital image with multiple color channels is disclosed. The method comprises negatively correcting a first color channel by subtracting an overshoot component of the first color channel. The subtraction is subject to a lower threshold, which is dependent on a local value of at least one further color channel.

Abstract: The present disclosure relates to a method of motion segmentation (100) in a video stream. The method comprises the steps of: acquiring (101) a sequence of image frames; dividing (102) a first frame (401) into a plurality of image blocks (403); comparing (103) each image block (403) against a corresponding reference image block (404) and providing a measure of dissimilarity; for image blocks having a measure of dissimilarity less than a threshold: discarding (104a) the image blocks, and for image blocks having a measure of dissimilarity greater than the threshold: keeping (104b) the image blocks and further dividing the image blocks into a new plurality of image blocks (405); repeating the steps of dividing (102) and comparing (103) until a stop condition is met (105a); generating (106) a motion mask (407) indicating areas of movement (408).
