An Effective Method for Removing Scratches and Restoring Low -Quality QR Code Images
نویسنده
چکیده
Quick Response Code is one types of 2D barcode. QR Code has been widely used in many fields. Here proposes a complete preprocessing system for restoring low-quality Quick Response code images. The system has been designed to deal with low contrast, rotated and deformed code images. If any scratches are present in QR code the decoding algorithm is unable to decode. This removal technique consists of multiple processes. The main advantage of this proposed system is to restore the code properly and efficiently. This system has been assessed on a database composed of 500 images captured by a different cell phones display. After the proposed preprocessing, 97.4 % of the images in the database were correctly decoded.

Improving Dark Channel Prior for Single Image Dehazing
This paper proposes an improved dark channel prior for removing haze from images. Dark channel prior is an effective method for removing haze. Dark channel is an image in the same size as the hazy image which is obtained by dividing the RGB images into windows and for each window, the minimum of each R, G and B channels are calculated. Then again the minimum of these three values is calculated ...
متن کاملA Study on Effective Digital Watermarking Method Suitable for QR code
Recently, many studies are being conducted related to the method of inserting the digital watermark in the QR code. The QR code is made up of a simple repeating black and white module and has many differences compared to general images. In this paper, a watermarking algorithm that can increase the amount of information to be concealed by minimizing the degradation of QR code image quality is pr...
متن کاملQuantization-based image authentication scheme using QR error correction
Image authentication, which is provided with capabilities of tamper detection and data recovery, is an efficient way to protect the contents of digital images. Vector quantization (VQ) is a data compression method. A VQcompressed code is not only a significant image authentication feature but also applicable in restoring possibly damaged pixels. However, if an image is tampered with, the necess...
متن کاملA two-stage quality measure for mobile phone captured 2D barcode images
2D barcodes are widely used in many commercial applications where a scanning device is normally used to capture them. When mobile phones are used to capture 2D barcodes, the obtained images are usually distorted due to cheap camera lens and sensors, handshake and poor lighting conditions. These badly distorted images require a long decoding process which results in an error message generated or...
