A novel object detection model based on Unit-linking PCNN
optical flow and topological property is proposed. In this paper
according to velocity differences between the moving object and its background
the approach calculates the velocity amplitude of each pixel of the image
through which the flow velocity amplitude are quantized using as threshold to decide whether a pixel is a part of an object or the background. Besides
using Unit linking PCNN whole filter expresses the connectivity and integrity
which are significant topology properties
in moving object attention selection. Experimental results on four databases indicate that the proposed method outperforms other methods both in detection accuracy and background suppression effect under the same conditions.
