Developing an algorithm for a visualization prototype often involves the direct comparison of different development stages and design decisions, even minor modifications may dramatically affect results. While existing tools provide visualizations gaining general insight into performance structural aspects source code, they neglect central importance result images unique to graphical algorithms....

Although the idea of reusing code is very appealing, effective reuse has long been acknowledged as a problem. To help address the difficulties, many advocate strong management commitment to code reuse, leading to the treatment of code as an asset to be carefully managed in a well-organized repository. However, the advent of the Web may bring a change to this outlook, encouraging informal, loose...

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...

Conceptual analysis in many domains uses visual representation of objects and relationships. This is obviously true for engineering domains where graphics is often a part of design documentation. It is true for software engineering as well, where we have well-established graphical representation of various software artifacts. Attempts are made to formalize the semantics of visual representation...

Closed-loop, model-based visual target recognition and tracking in extreme lighting conditions is expensive to develop and computationally resource-intensive. To reduce the development cycle, improve software reliability and reduce the computational requirements for such algorithms, we have adapted Maple code generation to the problem of automatically generating efficient implementations of fam...

The purpose of this research is to automatically segment and read visual code markers. These markers are found in standard 640x480 pixel color images that were acquired with standard VGA cell phone cameras. In this paper, we investigate an approach to automatically identify and read visual code markers. The experimental results show that the algorithm discussed in this paper successfully segmen...

A process for marker detection which involves adaptive thresholding, region-modeling and mapping has a challenge of recognizing marker in noisy space. We propose accurate and computationally efficient algorithm in detecting any number of marker within moderate tilt in camera image.

Two-dimensional visual code markers display bit-encoded information about nearby objects. To aid computer vision systems in extracting the bit patterns from images containing one or more markers, we developed a shape-based algorithm for detecting marker locations and orientations in order to identify the markers’ bit patterns. We show that the algorithm can correctly identify all bits for 12 tr...

Visual phonics is an instructional program to provide print awareness, alphabet knowledge, and sound-letter correspondence for children with hearing loss who experience difficulty developing a foundation of phonemic awareness skills. Its purpose is "to clarify the sound symbol relationship between spoken English and print" (Waddy-Smith & Wilson, 2003, p. 15). It is implemented in numerous schoo...
