Frame rate up-conversion is useful for low frame rate pictures such as movie. In case of conversion, basic motion compensation causes gap at covered area and uncovered area. To avoid the gap, we propose the motion compensation centered at the position of target. Fully motion compensated interpolation is possible in this method. To realize this, error normalizing by block activity is used for mo...

A theoretical model describes how an intermittent swimming style can be energetically advantageous over continuous swimming at high average velocities. Kinematic data are collected from high-speed ciné pictures of free swimming cod and saithe at high velocities in a burst-and-coast style. These data suggest that fish make use of the advantages shown by choosing initial and final burst velocitie...

Understanding the motions of the constituent atoms in reacting molecules lies at the heart of chemistry and is the central focus of chemical reaction dynamics. The most detailed questions one can ask are about the evolution of molecules prepared in a single quantum state to products in individual states, and both calculations and experiments are providing such detailed understanding of increasi...

This paper proposes the use of unequally protected key pictures to prevent temporal error propagation in error-prone video communications. The key picture may either be an intra-coded picture or a picture using a long-term motion compensation reference picture through reference picture selection. The inter-coded key picture uses previous key pictures as motion compensation reference. Key pictur...

In 6 experiments, incidental memory was tested for direction of motion in an old-new recognition paradigm. Ability to recognize previously shown directions depended greatly on motion type. Memory for translation and expansion-contraction direction was highly veridical, whereas memory for rotation direction was conspicuously absent. Similar results were obtained in conditions in which motions we...

This research examined the effects of motion expectations on memory for static pictures. The central hypothesis was that as implied motion for a picture increases, memory distortions will also increase in the direction of implied motion. A secondary hypothesis predicted that people will find pictures with increased implied motion more interesting than pictures with less implied motion. Experime...

In this work, the motion parameters of the bi-directionally predicted pictures (B-pictures) of MPEG-1,2 are exploited for concealment of large portions of corrupted anchor pictures that might arise due to channel errors or packet losses. To further enhance the quality of the concealed anchor pictures, we propose two methods of constraining the motion vectors of the B-pictures that strengthen th...

Due to its mechanical nature motion picture film has to cope with inaccuracies in positioning the single image in the moment of exposure, projection and scanning. This is the reason for steadiness errors that manifest in a jitter of the whole image. This jitter is not limited to translations but may also include rotational and shearing motion components. The amplitude of these erroneous movemen...
