correlation detection

correlation detection

[‚kär·ə′lā·shən di′tek·shən]
(engineering)
A method of detection of aircraft or space vehicles in which a signal is compared, point to point, with an internally generated reference. Also known as cross-correlation detection.

If the average similarity is smaller than the threshold e and the confidence degree of the attribute correlation is greater than or equal to the threshold [phi], it means that not only does the data sequence of the current time significantly deviate from the historical data, but also the relationship among the attributes is in accordance with the probability relation when the abnormal event occurs, which needs a further spatial correlation detection. In other cases, it will be filtered as a noise.
The time correlation detection consists of a cycle of O(s) times.
Therefore, the energy center where the composite features, such as target neighborhood of sequential image and area and concentration degree, are integrated is proposed to realize the multiframe motion correlation detection of the target.
In order to improve the detection and recognition ability of small targets in images, this paper first uses the improved anisotropy to predict the background and then adopts the improved high-order cumulates to enhance the target, and finally, on the basis of image background suppression and target enhancement, this paper proposes a new motion feature of local energy center of sequential image as a multiframe motion correlation detection algorithm.
