This paper shows new algorithms and the implementations of image reorganization for EAN/QR barcodes in mobile phones. The mobile phone system used here consists of a camera, mobile application processor, digital signal processor (DSP), and display device, and the source image is captured by the embedded camera device. The introduced algorithm is based on the code area found by four corners detection for 2D barcode and spiral scanning for 1D barcode using the embedded DSP. This algorithm is… Expand
Robust 1-D Barcode Recognition on Camera Phones and Mobile Product Information Display
TLDR
The proposed algorithm shows a close to 100% accuracy in real life situations and yields a very good resolution dependent performance on a database of barcode images, ranging from 90.5% (640 ×480) up to 99.2% (2592 ×1944). Expand
Stabilization and extraction of 2D barcodes for camera phones
TLDR
This paper proposes an efficient and effective algorithm to restore and extract 2D barcode from a complex background in a camera-shaken image and outperforms in not only smaller running time but also higher accuracy of the barcode recognition in the mobile computing. Expand

VCode—Pervasive Data Transfer Using Video Barcode
TLDR
A novel data transfer scheme that uses the camera in a smart phone as an alternative data channel that relies on visual communication and does not require special hardware or data plans to be implemented. Expand
Recognition of QR Code with mobile phones
TLDR
An image processing system based on mobile is described to be able to binarize, locate, segment, and decode the QR Code, and experimental results indicate that these algorithms are robust to real world scene image. Expand
Dynamic window construction for the binarization of barcode images captured by mobile phones
TLDR
The proposed scheme to dynamically determine the size of the binarization window, which changes with the presence of the high gradient pixels in a search window centering the processing pixel, has demonstrated its capability in handling objects of different sizes and the uneven illumination problem.

Object recognition using a tag
TLDR
This work proposes a method for object recognition in an unconstrained condition that should be able to establish camera position with respect to a landmark, recognise an object which is tagged with the calibration chart and test any camera calibration and 3D pose estimation routines, thus facilitating future research and applications in mobile robots navigation, 3D reconstruction and stereo vision.
