msg = readBarcode(I) detects and decodes a 1-D or 2-D barcode in the input image and returns the message associated with that barcode. If the input image contains multiple barcodes, the readBarcode function decodes only the first barcode detected.

This example shows how to use the readBarcode function from the Computer Vision Toolbox™ to detect and decode 1-D and 2-D barcodes in an image. Barcodes are widely used to encode data in a visual, machine-readable format.

Apr 5, 2011 · the following code reads bar-code and displays the corresponding decoded value using look up tables. black and white bars in a bar codes are correspondingly decoded to '0' or '1'. download the barcode images from google and see the code work!

Dec 5, 2016 · I have the following code in matlab to decode a barcode: if sum(sum(regions & (labels == i))) > largest_size. largest_size = sum(sum(regions & (labels == i))); index = i; end. for j = 1:cols. if region(i,j) == 1. barcode(i,j) = 255; end. for j = 1:cols. if region(i,j) == 1. if i < y1. y1 = i; end. if i > y2. y2 = i; end. if j < x1. x1 = j; end.

A barcode scanner written in Matlab which detects and recognizes the EAN-13 barcode using Image processing toolbox v 11.3

Developed a MATLAB Barcode Reader with a user-friendly GUI, utilizing the `readBarcode ()` function for decoding. The application excels in MATLAB programming, image processing, and GUI development, showcasing proficiency and enabling automated data extraction through image import and barcode result display.

Barcode reader designed to process and decode barcodes from images. GUI is developed using MATLAB's GUIDE tool. Decoding EAN-13 barcodes. Key functionalities are image preprocessing (grayscale conversion and rotation), region of interest selection (cropping), and barcode decoding through Fourier transformation and pattern matching.

This example shows how to use the From Video Device block provided by Image Acquisition Toolbox™ to acquire live image data from a Point Grey Flea® 2 camera into Simulink®. The example uses the Computer Vision Toolbox™ to create an image processing system which can recognize and interpret a GTIN-13 barcode.

barcode scanner that can extract and decode sequences on crowded backgrounds. It consists of three functions: barcode localization from the raw image, transformation of the localized barcode, and sequence decoding using an intelligent algorithm.
