Detection of Visual Code Markers in Camera-Phone Images

چکیده
We describe the algorithm design and implementation of our submission for the EE368 final project, which involves detection of visual code markers in camera-phone images. We describe our approach and results, as well as the challenges faced during the development of our algorithm. For the reader’s interest, we also include a brief account of the algorithmic possibilities which we explored but did not ultimately employ.

EE368 Project: Visual Code Marker Detection through Geometric Feature Recognition
Visual code markers are developed as a humanmachine interactive tool [1] [2]. In this class project, a code recognition program is developed to read code markers. The requirements of the code recognition program are high accuracy, speed and illumination insensitivity. There can be more than one visual code in the picture and the orientations of the visual codes are not restricted. The code mark...
متن کاملVisual Code Marker Detection
HE purpose of this project is to detect and read visual code markers in color images taken by camera phones. We are given a set of twelve training images, each containing up to three code markers with arbitrary location and orientation. Each code marker is an 11 x 11 array of black and white elements, 83 of which represent variable data bits. The remaining 38 elements are fixed and consist of t...
متن کاملVisual Code Marker Detection
a 2-dimensional visual code marker carries as much as 83 bits information. Thus it is a useful code marker system for storing and extracting information. This paper presents a digital image processing algorithm which automatically locates the marker on a cell-phone camera captured image. With the exact location of the code marker, detailed bits information of the visual code marker is returned....
متن کاملVisual Code Marker Detection
This report describes an algorithm designed to detect visual code markers as described in [1]. The algorithm assumes the images have resolution and quality similar to the ones captured by regular cellular phone cameras. Applications of the use of these visual code markers are described in [2].
متن کاملEE368 Final Project Report: Visual Code Marker Detection
This report presents a method for detecting visual code markers in cell phone images. INTRODUCTION Visual code markers are binary information bearing tags similar to bar codes except that they can be read with the use of a cell phone camera and detection algorithm (such as the one presented in this report). The concept of a visual code marker and its various uses are presented clearly in Michae...
