(Image Visualization in ERDAS IMAGINE)

2021

This article presents an evaluation of the ERDAS IMAGINE Spatial Model Editor from the perspective of effective cognition. Workflow models designed in Spatial Model Editor are used for the automatic processing of remote sensing data. The process steps are designed as a chain of operations in the workflow model. The functionalities of the Spatial Model Editor and the visual vocabulary are both important for users. The cognitive quality of the visual vocabulary increases the comprehension of workflows during creation and utilization. The visual vocabulary influences the user’s exploitation of workflow models. The complex Physics of Notations theory was applied to the visual vocabulary on ERDAS IMAGINE Spatial Model Editor. The results were supplemented and verified using the eye-tracking method. The evaluation of user gaze and the movement of the eyes above workflow models brought real insight into the user’s cognition of the model. The main findings are that ERDAS Spatial Model Edito...

The tremendous computing power needed for the inter active processing and generation of visual information is more and more becoming a major technology driver in the consumer market. Illustrative are the bench marks used by MacWorld magazine recently at the in troduction of the new generation of Power PC MACs (a major commercial event) used to compare the process ing power of the Power PC with the Intel Pentium and 486: Almost all of them where DTP image processing benchmarks. The majority of the word processor users (estimated at over 100 million people world wide) will evolve to DTP software in the coming years, following the line of ever improving (color) printers and scan ners at steadily eroding prices. The use of 3D graphics is quietly growing among professional users like Archi tects and Engineers. 3D graphics will explode when accelerators will reach price levels low enough for the game industry and will be one of the main ingredients for future multimedia platforms.

The interaction technology has not only covers the engineering aspects but also covers non-engineered fields. HCI areas includes as mobile and ubiquitous computing, social computing, interactive visualization and visual analytics,, etc. The researchers are doing the research work in the processing of images and traditional visualization techniques. But the technological improvements urge the combination of more than two technologies for direct or indirect interactions to enhance the quality of work. Therefore researchers are required to consider the objective as devising combinatory methodology to improve the research work. This motivates to proceed in the arena of interactive visualizations according to the user’s ontological perspective. The simulation of work has been carried out in opencv with numpy using python language. The simulation results show that the best interactions are possible by involving the magnitude spectrum of visualized image, SURF and interactive annotation of images.

We have developed a computer software package, IMOD, as a tool for analyzing and viewing threedimensional biological image data. IMOD is useful for studying and modeling data from tomographic, serial section, and optical section reconstructions. The software allows image data to be visualized by several different methods. Models of the image data can be visualized by volume or contour surface rendering and can yield quantitative information.

Digital practices are shaped by graphical representations that appear on the computer screen, which is the principal surface for designing, visualizing, and interacting with digital information. Before any digital image or graphical interface is rendered on the screen there is a series of layers that affect its visual properties. To discover such processes, it is necessary to investigate software applications, graphical user interfaces, programming languages and code, algorithms, data structures, and data types in their relationship with graphical outcomes and design possibilities. This book studies interfaces as images and images as interfaces. It offers a comprehensible framework to study graphical representations of visual information. It explores the relationship between visual information and its graphical supports, taking into account contributions from fields of visual computing. Graphical supports are considered as material but also as formal aspects underlying the representation of digital images on the digital screen.

Data visualization includes introducing data in graphical or pictorial structure, which makes the data straightforward. Data visualization is a totally new and promising discipline in software program engineering.. Its employments PC realistic impacts to uncover the examples, patterns, connections out of datasets. It assists with clarifying realities and decide blueprints. It will profit any field of study that requires inventive methods of introducing huge, complex data. The coming of PC illustrations has molded current visualization. This paper presents a short prologue to data visualization.

In this paper we discuss the application of the Object Oriented Programming (OOP) paradigm to the development and implementation of a software system for the interactive visualization of CFD data. We show that OOP provides both a powerful framework to analyze and design the system as well as an efficient implementation tool.In particular we show how a high degree of interactivity and user-friendliness can be achieved through the use of class libraries encapsulating graphics, networking and interfacing. We illustrate our approach with examples taken from the development of CFView, which is an advanced interactive visualization tool capable of handling both structured and unstructured meshes. We include a discussion of how OOP facilitates parallelization.

Background: Visualizing 3-dimensional (3-D) datasets is an important part of modern neuroimaging research. Many tools address this problem; however, they often fail to address specific needs and flexibility, such as the ability to work with different data formats, to control how and what data are displayed, to interact with values, and to undo mistakes. Results: iiV, an interactive software program for displaying 3-D brain images, is described. This tool was programmed to solve basic problems in 3-D data visualization. It is written in Java so it is extensible, is platform independent, and can display images within web pages. iiV displays 3-D images as 2-dimensional (2-D) slices with each slice being an independent object with independent features such as location, zoom, colors, labels, etc. Feature manipulation becomes easier by having a full set of editing capabilities including the following: undo or redo changes; drag, copy, delete and paste objects; and save objects with their features to a file for future editing. It can read multiple standard positron emission tomography (PET) and magnetic resonance imaging (MRI) file formats like ECAT, ECAT7, ANALYZE, NIfTI-1 and DICOM. We present sample applications to illustrate some of the features and capabilities. Conclusion: iiV is an image display tool with many useful features. It is highly extensible, platform independent, and web-compatible. This report summarizes its features and applications, while illustrating iiV's usefulness to the biomedical imaging community.

Medical image visualization system, which is of great value in medical research and clinic diagnosis, has been a focal field in recent years. IDL (Interactive Data Language) has a vast library of built-in math, statistics, image analysis and information processing routines, therefore, it has become an ideal software for interactive analysis and visualization of two or three dimensional scientific datasets. The principles and development are proposed to design a novel three dimensional visualization toolbox for medical images based on IDL platform using object oriented programming and object graphics techniques, with experimental results exhibited. It is demonstrated that our developed toolbox can carry out interactive volume and slice operations in both two and three dimensions effectively and efficiently, meanwhile, it has advantages of extensive applicability, friendly interaction, convenient extension and favorable transplantation, which is adequate for medical images processing and analysis.
