A color palette is one of the simplest and most intuitive descriptors that can be extracted from images or videos. This paper proposes a method to assess similarity between palettes by sorting colors. While previous measures compare only colors without considering overall combination, we sort minimize geometric distance align them share common tendency. We propose dynamic closest warping (DCCW)...

We reduced time to detect target symbols in mock radar screens by partitioning displays in accordance with task instructions. Targets appeared among distractor symbols either close to or far from the display center, and participants were instructed to find the target closest to the center. Search time increased with both number of distractors and distance of target from center, and the effect o...

Disagreements exist regarding the manner in which weight should be dynamically shared both withinand between-feet to generate maximal golf clubhead speed. The purpose of this study was test the null hypothesis that maximum plantar pressure (PP) distributions do not correlate with clubhead speed. Thirty-two amateur golfers (handicaps: 2.7-25) performed 10 swings with a driver. Clubhead speed was...

This work presents a new perceptually motivated bit allocation strategy for Region of Interest (ROI) coding in video sequences. It is not possible to assure any minimum target foreground quality in the approaches reported so far in the literature. In our proposed strategy reported herein, the bit-allocation is based on a target quality for the foreground and allowing perceptually tolerable grac...

We reduced time to detect target symbols in mock radar screens by adding perceptual boundaries that partitioned displays in accordance with task instructions. Targets appeared among distractor symbols either close to or far from the display center, and participants were instructed to find the target closest to the center. Search time increased with both number of distractors and distance of tar...

As the closest unicellular relatives of animals, choanoflagellates serve as useful model organisms for understanding the evolution of animal multicellularity. An important factor in animal evolution was the increasing ocean oxygen levels in the Precambrian, which are thought to have influenced the emergence of complex multicellular life. As a first step in addressing these conditions, we study ...

Given a set S of n points in k-dimensional space, and an L t metric, the dynamic closest pair problem is deened as follows: nd a closest pair of S after each update of S (the insertion or the deletion of a point). For xed dimension k and xed metric L t , we give a data structure of size O(n) that maintains a closest pair of S in O(log n) time per insertion and deletion. The running time of algo...

We propose a quantum algorithm for closest pattern matching which allows us to search for as many distinct patterns as we wish in a given string (database), requiring a query function per symbol of the pattern alphabet. This represents a significant practical advantage when compared to Grover’s search algorithm as well as to other quantum pattern matching methods [7], which rely on building spe...

A closer look is taken at the well-known divide-andconquer algorithm for finding the closest pair of a set of points in the plane under the Euclidean distance. An argument is made that it is sufficient, and sometimes necessary, to check only the next three points following the current point associated with the y-sorted array in the combine phase of the algorithm.
