Abstract
In general, out-of-focus blur is considered to be disturbance that reduces the detection accuracy for object detection, and many researchers have tried to remove such noise. The authors proposed an object detection scheme that exploits information included in image blur. This scheme showed good accuracy for object detection, but it has a critical problem: huge computational cost is required owing to the DFT needed to evaluate image blur. This paper proposes a novel object detection scheme using the difference in image blur evaluated with simple spatial-domain filtering. Experimental results using synthetic images show that the scheme achieves perfect classification, though our previous scheme has about a 2.40% miss rate at 0.1 FPPI for circle detection. In addition to the improvement in accuracy, the processing speed becomes about 431 times faster than that of the old scheme.
