There are disclosed various methods, apparatuses and computer program products for volumetric video encoding and decoding. In some embodiments of a method for encoding, obtaining one or more patches formed from a three-dimensional image information are obtained. The one or more patches represent projection data of at least a part of an object to a projection plane. Priority for at least one of the one or more patches is determined and the one or more patches are projected to a projection plane. Indication of the priority is encoded into or along a bitstream. In some embodiments of a method for decoding, one or more encoded patches formed from a three-dimensional image information are received. Also at least one indication of priority determined for at least one of the one or more patches is received and the patches are reconstructed in the order defined by the at least one indication of priority.

One embodiment provides a method, including: initiating, using at least one camera of an information handling device, a video feed; receiving marking input on an object in the video feed; identifying, using at least one distance sensor of the information handling device, distance information from the information handling device to the object; and providing, in the video feed and presented concurrently with the marking input, a visual overlay of the distance information. Other aspects are described and claimed.

There is provided an image processing apparatus comprising. An obtainment unit obtains a first circular fisheye image accompanied by a first missing region in which no pixel value is present. A generation unit generates a first equidistant cylindrical projection image by performing first equidistant cylindrical transformation processing based on the first circular fisheye image. The generation unit generates the first equidistant cylindrical projection image such that a first corresponding region corresponding to the first missing region has a pixel value in the first equidistant cylindrical projection image.

A processor system and computer-implemented method may be provided for generating a composite video stream which may combine a background video and a foreground video stream into one stream. For that purpose, a spatially segmented encoding of the background video may be obtained, for example in the form of a tiled stream. The foreground video stream may be received, for example, from a(nother) client device. The foreground video stream may be a real-time stream, e.g., when being used in real-time communication. The image data of the foreground video stream may be inserted into the background video by decoding select segments of the background video, inserting the foreground image data into the decoded background image data of these segments, and by encoding the resulting composite image data to obtain composite segments which, together with the non-processed segments of the background video, form a spatially segmented encoding of a composite video.
