Online documentation for VideoBarCode1D

Attempt to read 1D barcode from image - very unreliable (works with Media/Video/Analysis framework ).

Description

An attempt to read 1D barcodes from images. Very unreliable. Also dogged by problems of getting a decent image of a bar code using a normal webcam, e.g. focal distance typically much longer, resolution limited.

Installation

See JMFVideoCaptureManager for video capture requirements.

Configuration

threshold can be set to change the black/white threshold used when looking for bar codes.

Usage

Currently looks at each input line, starting from the centre. Generally a good idea to run through a Drop and Subsample fist (e.g. Drop(3),Subsample(1,10)). Currently pretty knackered. Currently outputs bit sequence as string. Does not output any positional information. Currently stops at the first barcode.

Technical Details

Currently pretty knackered.
