Weboped an optimization framework to determine optimal track class assignment based on the minimization of track maintenance and trans-portation costs (6). Liu et al. presented a benefit–cost analysis frame-work to consider the trade-off between reduced accident rates and increased track maintenance costs in evaluating track class upgrade WebMotion estimation is the process of determining the movement of blocks between adjacent video frames. This toolbox includes motion estimation algorithms, such as optical flow, block matching, and template matching. These algorithms create motion vectors, which can relate to the whole image, blocks, arbitrary patches, or individual pixels.
