Decode Unreadable Barcodes with Dynamsoft Barcode Reader's Custom Scan Parameters
Binarized image produced by Dynamsoft Barcode Reader:
JSON Template (help):
Issue:
Barcodes rely on precise spacing and width ratios between black bars and white spaces to encode data. When a barcode is crumpled, the bars may become stretched, compressed, or skewed, altering their intended proportions.
Solution:
Dynamsoft Barcode Reader SDK provides several DeformationResistingModes to overcome deformation.
