چکیده
Aiming at the 2D color barcode images captured by mobile phone camera under complex environment, this paper presents a novel segmentation algorithm of 2D color barcode image based on gradient features. Firstly, the gradient image can be obtained by extracting gradient features from the image captured. Then the DCT transformation algorithm is used to partition the gradient image and the enhanced coefficient of each block is calculated. The enhanced coefficient will be used to distinguish the barcode region and non-barcode region. Finally, the barcode region can be segmented accurately by using morphology and convex hull algorithm. The experimental results show that this approach has a good performance on segmentation. It can segment the barcode region from the 2D color barcode image captured by camera under different environments.
