  We present a set of tools for detecting small-scale solar magnetic
cancellations and the disk counterpart of type II spicules (the so-called Rapid
Blueshifted Excursions (RBEs)), using line-of-sight photospheric magnetograms
and chromospheric spectroscopic observations, respectively. For tracking
magnetic cancellation, we improve the Southwest Automatic Magnetic
Identification Suite (SWAMIS) so that it is able to detect certain obscure
cancellations that can be easily missed. For detecting RBEs, we use a
normalized reference profile to reduce false-positive detections caused by the
non-uniform background and seeing condition. Similar to the magnetic feature
tracking in SWAMIS, we apply a dual-threshold method to enhance the accuracy of
RBE detection. These tools are employed to analyze our coordinated observations
using the Interferometric BIdimensional Spectrometer at Dunn Solar Telescope
(DST) of the National Solar Observatory (NSO) and Hinode. We present the
statistical properties of magnetic cancellations and RBEs, and explore their
correlation using this data set.
