In this paper, we present a new image compression scheme, which is specially designed for computer generated compound color images. First we classify the image content into two kinds: text/graphic content and picture content. Then a rate-distortion optimized color quantization algorithm is designed for text/graphic content, which introduces distortion to text content and minimizes the bit rate ...

Computational ghost imaging (CGI) is a single-pixel imaging technique that exploits the correlation between known random patterns and the measured intensity of light transmitted (or reflected) by an object. Although CGI can obtain twoor threedimensional images with a single or a few bucket detectors, the quality of the reconstructed images is reduced by noise due to the reconstruction of images...

This paper presents research on the development of digital collages and investigations into the cognitive efforts of graphic designers. The research venue was an upper level undergraduate course in computer graphics. Work in the course focused on the use of digital imaging software (Adobe Photoshop) and the creation, manipulation, use and understanding of images. Graphic design students manipul...

Abundant high-quality computer images are available on the Internet and elsewhere, yet many are virtually inaccessible to the blind computer user. This paper introduces research in the development of a system for automatic conversion of any digitized image into a comprehensible tactile graphic form. An experimental software and hardware system is presented, and preliminary test results are disc...

Conventional computational ghost imaging (CGI) uses light carrying a sequence of patterns with uniform-resolution to illuminate the object, then performs correlation calculation based on intensity value reflected by target and preset obtain object image. It requires large number measurements high-quality images, especially if high-resolution images are be obtained. To solve this problem, we dev...

This paper will explore the potential for the SUM tool, intended initially for the sonification of images, as a tool for graphical computer-aided composition. As a user library with a graphical user interface within the computeraided composition environment of PWGL, SUM has the potential to be used as a graphical approach towards computer-aided composition. Through the re-composition of the gra...

We presented a set of physics motivated features for classifying photographic and computer graphic images in our previous work [1]. We also deployed an online demo system for distinguishing photographic and computer graphic images in October 2005 [2], which features our geometry classifier, together with the wavelet classifier, and the cartoon classifier. On the first anniversary of its launch,...

In this study, we demonstrated a framework for improving the image quality of computational ghost imaging (CGI) that used conditional generative adversarial network (cGAN). With set low-quality images from CGI system and their corresponding ground-truth counterparts, cGAN was trained could generate high-quality new images. The results showed compared with traditional method based on compressed ...
