Recent trend of bigger and high resolution mobile display for smart-phone leads the needs of high performance of power saving technologies. Among those technologies, the representative technology is PenTile L6W technology which uses RGBW pixel and sub-pixel rendering algorithm. In this paper, the PenTile L6W and the other technologies are introduced. To achieve this power saving, display pixel structure...
Illumination makes an important role in realistic graphics rendering, especially in the mixed-scene rendering based on the geometric models and images. Adjusting illumination effect is a key step to achieve realistic scene when the images are inconsistent with the virtual environment. Therefore, complicated processing is required to generate the image with desired illumination condition. Using the...
Subpixel-based down-sampling is a method that can potentially improve the apparent resolution of a down-scaled image by controlling individual subpixels rather than pixels. However, the increased luminance resolution often comes at the expense of chrominance distortion. In this paper, we formulate the subpixel-based down-sampling as a Min-Max problem (Min-Max Directional Error) which we call MMDE...
Subpixel-based down-sampling is a method that can potentially improve the apparent resolution of a down-scaled image by controlling individual subpixels rather than pixels. However, the increased luminance resolution often comes at the price of chrominance distortion. In this paper, we propose a new subpixel-based down-sampling scheme for which we design a two-dimensional image reconstruction model...
According to the jacquard technology, we present an enhanced halftoning algorithm for which the filter weights and the quantizer thresholds vary depending on input pixel value. This minimization brings the Fourier spectra of the selected key intensity levels as close as possible to the corresponding "blue noise" spectra. The continuity of the algorithm's behavior across the full range of...
The image analogy is a classical technique used in the style learning and Multimedia data mining. To regrettable the IA method can not be suitable to any pair of images. This article prime task has four aspects: 1 Proposed one kind of new image similarity measure operator. 2 Take Image difference measure operator as characteristic quantification IA method applicable scope. 3 To proposed one kind of...
This paper presents a new GPU-based implementation of fast non-local means (NLM) filtering for material restyling. Our fast NLM filtering algorithm is able to achive realtime feedback of interactive image editing. Furthermore a novel material editing method based on our fast NLM filtering is proposed to change the material appearance of image-based objects. Given an input image, an alpha matte is...
Many artists attempt to make art work from famous celebrated picture or old masters. Normally they implement it in drawing or printing using photoshop to analysis the old masters and remake them. It is not special art work in modern art field. We attempt to remake them using directional line drawing alogorithm . It is one of NPR(non-photorealistic rendering, it is introduced in this paper. We implement...
