Imaging and visualization techniques for aircraft security are discussed. Planar transmission imaging techniques using x-rays and nuclear radiation are described along with their intrinsic limitations. Methods for distinguishing materials using dual - energy and multi-energy x-ray sources are shown along with techniques for simulating materials with ...

Image information and visual quality
IEEE Transactions on Image Processing, 2004Measurement of visual quality is of fundamental importance to numerous image and video processing applications. The goal of quality assessment (QA) research is to design algorithms that can automatically assess the quality of images or videos in a perceptually consistent manner.

Non-visual consciousness and visual images in blindsight
Consciousness and Cognition, 2012In a recent response paper to Brogaard (2011a), Morten Overgaard and Thor Grünbaum argue that my case for the claim that blindsight subjects are not visually conscious of the stimuli they correctly identify rests on a mistaken necessary criterion for determining whether a conscious experience is visual or non-visual.

Reservation Through Image Visualization
International Conference on Computer Graphics, Imaging and Visualisation (CGIV'06), 2006In tourism industry, reservation or booking through the Internet is now so common; it is becoming the practice among the big or small industry players. However, what is missing and lacking is the concept of virtual imaging that represent the ongoing transaction. For this paper, the focus is visualizing real time reservation for an island-based vacation

A visual language for image processing
Proceedings of the 1990 IEEE Workshop on Visual Languages, 2002The visual language Contata is a simple, but powerful, programming environment for the KHOROS system. By providing a graphical interface to basic components in the form of block diagrams with which researchers in many fields are already familiar, Contata promotes experimentation and learning without the need for advanced programming skills.

Image hatching for visual cryptography
ACM Transactions on Multimedia Computing, Communications, and Applications, 2012Image hatching (or nonphotorealistic line-art) is a technique widely used in the printing or engraving of currency. Diverse styles of brush strokes have previously been adopted for different areas of an image to create aesthetically pleasing textures and shading.

Visual Cryptography for Natural Images and Visual Voting
2013Visual cryptography is a type of secret sharing which encodes a secret image into several shadow images in such a way that the stacking of certain images printed on transparencies will reveal the secret. The decryption is done directly by the human visual system without any extra calculations.

Visualization Blackboard-visualizing 3D PET images
IEEE Computer Graphics and Applications, 1991Characteristics of positron emission tomography (PET) images that limit human ability to accurately perceive the information the images contain are discussed. They are relatively low spatial resolution, a lack of apparent anatomical information and the expression of metabolic activity in terms of brightness levels (gray levels), which are not ...

Procedural Image Processing for Visualization
2006We present a novel Procedural Image Processing (PIP) method and demonstrate its applications in visualization. PIP modulates the sampling positions of a conventional image processing kernel (e.g. edge detection filter) through a procedural perturbation function.

Perception and visualization of line images
Proceedings., International Conference on Image Processing, 2002This paper deals with state-of-the-art novel ideas of visualization, understanding and interpretation of two-dimensional (2D) line images. A new strategy using fast two-pass parallel pattern matching techniques is presented. It can learn, represent, visualize, and interpret 2D polyhedral line images with only very few learning samples.
