چکیده

Tone mapping of high dynamic range (HDR) images for realistic display is a commonly studied. However, scientific visualization of HDR image for analysis of scene luminance has much less attention. In this paper, we have presented and implemented a simple approach for the reproduction and visualization of the color information in HDR images. We attempt several simple color visualizing functions, and estimate their effectiveness through the evaluation factors with common HDR images.

Uncertainty Visualization using HDR Image Maps

Effective visualization of uncertainty associated with data has many applications in science and engineering. Visualization of a 3D scalar data set that displays detailed variations in uncertainty as well as in data is a challenging problem. We explore a novel approach to address the problem using High Dynamic Range (HDR) image maps. We use a transfer function that maps each data point to a col...

Image Retrieval Using Dynamic Weighting of Compressed High Level Features Framework with LER Matrix

In this article, a fabulous method for database retrieval is proposed.  The multi-resolution modified wavelet transform for each of image is computed and the standard deviation and average are utilized as the textural features. Then, the proposed modified bit-based color histogram and edge detectors were utilized to define the high level features. A feedback-based dynamic weighting of shap...

Interactive Extraction of High-Frequency Aesthetically-Coherent Colormaps

Color transfer functions (i.e. colormaps) exhibiting a high frequency luminosity component have proven to be useful in the visualization of data where feature detection or iso-contours recognition is essential. Having these colormaps also display a wide range of color and an aesthetically pleasing composition holds the potential to further aid image understanding and analysis. However producing...
