WebThe official documentation for edge specifies . thresh is a two-element vector in which the first element is the low threshold, and the second element is the high threshold. If you … WebUse edge detection algorithms such as the Canny edge detector or the Sobel operator to detect the edges of the barcode and remove any unwanted edges using the edge function. Finally, apply a mask to the original image using the segmented barcode to remove the non-barcode regions. Here is an example code snippet that demonstrates the above steps:

WebCanny edge detection is accomplished using the edge function. Matlab will get "automatic/adaptive" thresholds if you don't specify thresholds as an argument. An easy way to implement this is to simply call Edge twice; first to get an initial capture of the thresholds, then to adjust thresholds as needed based on the automatic thresholds.
