Enhancing the recognition rate of Two-Dimensional Barcodes Image and applications

QR Code Detection Based on Local Features

“…It can be observed that the average detection time of our method is about 27.5ms. As non-code region is first excluded by feature matching, the processing speed of our method is superior than method in [16], especially for picture with large background. …”

“…The compressed domain method should encode the image first, which needs additional computation, thus not very efficient. In [16] the special ratio of finder patterns is used for detection by directly scanning the whole image. This method is quite simple and the accuracy is high.…”

“…Experiments are conducted on a Windows 7 platform, Intel(R) Core(TM) i3 CPU, 2.53GHz. The directly scanning method in [16] using the special ratio of finder patterns is used for comparison. Table 1 illustrates the average processing time of method in [16] and different stages in our method.…”
