Adaptive early jump-out technique for fast motion estimation in video coding.
As shown in figure 9, the SPISY use a template which has the size of 1 6 of the original image width by 4 5 of the original image height, and is locating at 1 6 of the original image width to the right boundary and 1 10 of the image height....

 Motion Tips
The type of motion blur which samples at various times within the shutter interval is often referred to as 3D motion blur, whereas the term 2D motion blur typically refers to a post process to rendering.
When motion is detected at a given spatial sample location, mental ray selects equally spaced times within this range for a number of temporal samples, and then averages them together to create the effective spatial sample at that location.
Motion is detected when either a motion transformation, or motion vectors, direct an object through the spatial sample location.

 Motion portrayal
When a foreground element in motion is eye-tracked on a pulse width modulated display, the width of the blur depends on the intensity of the element.
The tall white rectangle in the lower half is in motion to the right with respect to the camera; during the frame interval, it moves by the amount indicated by the arrow.
For objects in motion with respect to a video or film camera, there is an inherent trade-off between a long exposure time, which will cause blurring of moving elements that the viewer is eye tracking, and a short exposure time, which will cause strobing of moving elements that the viewer is not tracking.

 Fast motion-compensated video frame interpolator - Patent 6618439
vm,n(p) denotes the displacement motion vector for pixel p from ftm to ftn, where the displacement motion vector is defined as the inter-image motion of the contects of a respective macroblock.
The motion compensated interpolation means may include a gap closure unit for processing gaps in the interpolated moving object block (MOti) to obtain increased solid areas in the interpolated moving object block (MOti) to improve a quality of the interpolated frame.
Motion post-processing of block-based motion field and pixel information by the motion vector replacement unit 13 is performed to determine whether a value of a motion vector V(B(p)) should be replaced, for example by a median value of eight nearest neighbor surrounding macroblock values.

The output of the ME (a motion vector for each MB) is then fed into the motion compensation system, where the differences between the MB and the predicted 16×16 blocks in the reference frame are entropy coded.
Fast block-matching search algorithms work by subsampling the search space on the premise of a slowly varying, continuous distortion function, where the distortion increases monotonically as one moves away from the minimum distortion.
Another fast search method that depends on the assumption of a slowly varying and monotonic distortion function is the "conjugate direction search." In this scheme, a modified 1D search is performed along one direction.

 Search Algorithms for Block-Matching in Motion Estimation
However, when there is motion in a sequence, then a pel on the same part of the moving object is a better prediction for the current pel.
There are other approaches to the problem like the Hierarchical motion vector estimation using the Mean Pyramid where the image is broken down into lower resolution components and the motion vectors for this lower resolution image are computed and propagated down the pyramidal structure of better and better resolution images.
Spatial dependency check the correlation between the motion vectors of neighboring blocks to provide a prediction to the previous matching algorithms.Frequently the prediction is formed by taking a weighted average of the neighboring motion vectors.

The higher the latitude, the further east the trough is relative to the looping storm.
One disadvantage is that storm motion is better correlated with deep layer mean or mid-level steering flow.

 Animation Formats - Hypereye Motion Graphics
Whole frames display fast motions that can be rather jumpy because there is no interleaved - dual frame information, only a single whole frame.
All motion in every frame is a blending of pairs of frames which smooths out the motion giving you a silky smooth image motion.
A section of an animation frame was chosen because of its fast motion.

 DVXuser.com : Understanding the New Framerates on the HVX200
In film, slow motion is shot by running the camera at a faster frame rate.
Prior to the introduction of genuine over/undercrank, video shooters had to try to synthesize slow motion effects in their nonlinear editors, and this leads to frames being blended together, footage being de-interlaced, new frames being interpolated, and all sorts of other compromises that resulted in lower-quality footage and a less-than-filmlike slow motion experience.
With 60p you’ll have video-looking footage, with no capability for slow motion but with tremendous fast-motion capability: imagine 1fps acquisition played back at 60fps – it’d be 60-to-1 fast motion.

 Journal of Vision - Illusory motion from change over time in the response to contrast and luminance, by Backus & ...   (Site not responding. Last check: )
A striking illusion of motion is generated by static repeated asymmetric patterns (RAPs) such as Kitaoka's (2003) “Rotating Snakes” and Fraser and Wilcox's (1979) peripheral drift illusion.
An essential part of this explanation is that motion detectors fail to compensate for the dynamics of neuronal encoding.
We argue that static natural patterns also generate local gain changes, but that these signals do not often trigger illusory motion because they are not usually aligned to drive global motion detectors.

Unlike a normal slow motion, no frames are repeated, so there is no "jerky" motion.
