Methods are provided for estimating motion between images associated with a common region of interest, the method comprising: providing frames including a reference frame and a target frame; determining a global motion vector based on a comparison of the reference and target frames; for a plurality of local blocks, determining local motion vectors between the reference and target frames based on the global motion vector to form globally adjusted local motion vectors; considering the globally adjusted local motion vectors as motion estimator.

A corresponding system is also disclosed.

[Object] To obtain more useful images when images taken using a fisheye lens are used without being remapped. [Solution] Provided is an image processing device including: an image acquisition unit that acquires taken images taken in chronological succession via a fisheye lens; a vector acquisition unit that acquires motion vectors from the taken images; and a point detection unit that detects a point of origin or a point of convergence of the motion vectors.

The display of correct and reliable operating image data which may change over the time is correctly and reliably displayed. A secured image is generated based on a source image by generating at least one secured image part. The secured image part is generated by combining a source image part of the source image with a corresponding secure pattern. The displaying of the secured image is monitored by detecting the corresponding secure pattern of the secured image part, updating the detected secure pattern, checking the currentness or correctness of the detected secure pattern

A method of video processing includes determining a first motion displacement Vx(x,y) at a position (x,y) and a second motion displacement Vy(x,y) at the position (x,y) in a video block coded using an optical flow based method, wherein x and y are fractional numbers, where Vx(x,y) and Vy(x,y) are determined based at least on the position (x,y) and a center position of a basic video block of the video block, and performing a conversion between the video block and a bitstream representation of the current video block using the first motion displacement and the second motion displacement.
