Abstract: A method and system are disclosed. The method may include receiving instructions in a hardware accelerator coupled to a computing device. The instructions may describe operations and data dependencies between the operations. The operations and the data dependencies may be predetermined. The method may include performing a splitter operation in the hardware accelerator, performing an operation in each of a plurality of branches, and performing a combiner operation in the hardware accelerator.

Abstract: A method and encoder for video encoding a sequence of frames is provided. The method comprises: receiving a sequence of frames depicting a moving object, predicting a movement of the moving object in the sequence of frames between a first time point and a second time point; defining, on basis of the predicted movement of the moving object, a region of interest (ROI) in the frames which covers the moving object during its entire predicted movement between the first time point and the second time point; and encoding a first frame, corresponding to the first time point, in the ROI and one or more intermediate frames, corresponding to time points being intermediate to the first and the second time point, in at least a subset of the ROI using a common encoding quality pattern defining which encoding quality to use in which portion of the ROI.

Abstract: A scene is monitored by receiving image data representing a thermal image captured by a thermal image sensor (13) and a visual image captured by a visual image sensor (15), the thermal image and the visual image depicting a same view of the scene. Objects (9) are detected in the visual image and in the thermal image. A mask (17a) is defined in the view of the scene, and it is determined if an object (9) or an object part, inside the mask (17a), is present in both the thermal image and the visual image. If so, a modified mask (17b) is provided by excluding an area occupied by the object (9) or the object part from the mask (17a).
