- Abstract: Moving target detection plays an important role in computer vision. However,
traditional algorithms such as frame difference and optical flow usually suffer
from low accuracy or heavy computation. Recent algorithms such as deep
learning-based convolutional neural networks have achieved high accuracy and
real-time performance, but they usually need to know the classes of targets in
advance, which limits the practical applications. Therefore, we proposed a
model free moving target detection algorithm. This algorithm extracts the
moving area through the difference of image features. Then, the color and
location probability map of the moving area will be calculated through maximum
a posteriori probability. And the target probability map can be obtained
through the dot multiply between the two maps. Finally, the optimal moving
target area can be solved by stochastic gradient descent on the target
probability map. Results show that the proposed algorithm achieves the highest
accuracy compared with state-of-the-art algorithms, without needing to know the
classes of targets. Furthermore, as the existing datasets are not suitable for
moving target detection, we proposed a method for producing evaluation dataset.
Besides, we also proved the proposed algorithm can be used to assist target
tracking.

Most GPS trajectory datasets include stay-points irregularity, which makes map-matching algorithms mismatch trajectories to irrelevant streets.
We cluster stay-points in a trajectory dataset with DBSCAN and eliminate redundant data to improve the efficiency of the map-matching algorithm.
Our approach yields 27.39% data size reduction and 8.9% processing time reduction with the same accurate results as the previous fuzzy-logic based map-matching approach.
