Abstract: An apparatus and method of estimating an image optical flow are provided. The method includes receiving temporally-consecutive first and second images; calculating rates of change of brightness values of pixels in the received temporally-consecutive first and second images; calculating a first optical flow estimation result value of a first pixel within the first image and a second optical flow estimation result value of a second pixel within the second image by using the calculated rates of change; comparing the first optical flow estimation result value with the second optical flow estimation result value; and correcting the first optical flow estimation result value and the second optical flow estimation result value by using a result of the comparison.

Abstract: A probing assembly includes a TDR probe coupling a time-domain reflectometry (TDR) device with a semiconductor device including a transistor therein, the transistor having a gate electrode, a source electrode, and a drain electrode on a substrate, wherein the TDR probe includes a first probe tip connecting the gate electrode to a signal line of the TDR device, and second to fourth probe tips connecting the source electrode, the drain electrode, and a bulk region of the substrate to ground lines of the TDR device, respectively.
