Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for edge detection of a two-dimensional code image. Background technique [0002] In image recognition and processing, there is inevitably the problem of finding the edge between the target and the background, and the accuracy of edge detection directly affects the accuracy and performance of subsequent image processing steps. Image recognition and processing have been paid more and more attention, and the processing performance requirements are getting higher and higher, but some edge detection algorithms in the prior art are relatively complicated or have low precision, which affects the processing effect of subsequent steps. [0003] Name: An image edge detection method and device (application number: 201410218968.1). The disclosed edge detection method obtains edge detection by setting the operator corresponding to the window. The detection algori...
