چکیده
In order to improve the efficiency and effectiveness of 2D barcode detection algorithm under complex background, detection algorithm for Data Matrix 2D bar code based on regional features analysis and locating method of line Snake algorithm is presented in this paper. Firstly, the region which contains "Ltype" barcode border is selected by analyzing the features of each region. Secondly, the barcode border is located by using line Snake algorithm, and the four vertices of the barcode are fitted. Finally, the barcode is rectified by using transmission shift. Experiments show that the detection algorithm of 2D barcode has good performance, and it is better than traditional barcode detection algorithm. It has strong anti-interference capacity, and can satisfy the needs of real-time on cell phone.

متن کاملImage Blur Detection with 2D Haar Wavelet Transform and Its Effect on Skewed Barcode Scanning
An algorithm is presented for image blur detection with the 2D Haar Wavelet transform (2D HWT). The algorithm classifies an image as blurred or sharp by splitting it into N x N tiles, applying several iterations of the 2D HWT to each tile, and grouping horizontally, vertically, and diagonally connected tiles with pronounced changes into tile clusters. Images with large tile clusters are classif...
متن کاملAutomatic Location for Multi-symbology and Multiple 1d and 2d Barcodes
Multi-symbology barcode location is a practical and challenging issue. Image-based barcode recognition techniques are robust and extendable approaches for reading versatile one-dimensional (1D) and two-dimensional (2D) barcodes. Most methods may work for a single 1D or 2D barcode or rely on a unique pattern to locate a single 1D or 2D barcode. This work proposes a general localization framework...

متن کاملA Novel 2D Marker Design and Application for Object Tracking and Event Detection
In this paper we present a novel application which uses 2D barcode for object tracking and event detection. We analyze the relationship between the spatial efficiency of a marker and its robustness against defocusing. Based on our analysis we design a spatially efficient and robust 2D barcode, M-Code (MarkerCode) which can be attached to the surface of static or moving objects. Compared with tr...
