A Simple Web Canvas Region Selection Tool for Barcode Region Detection

The barcode localization algorithm is an essential step for barcode recognition within an image. However, for static images, the bigger size images have, the much more time the algorithm takes. Plus, the success rate of the algorithm may be interfered by the background color and the foreground color. It is tough to guarantee a 100% success rate for locating barcodes. If the auto-detection fails, a viable workaround is to switch to the manual mode, selecting the barcode regions by your eyes, in order to recognize the barcodes you want. In this article, I will demonstrate how to create a simple web canvas region selection tool to do barcode region detection using Dynamsoft JavaScript Barcode SDK.
