Efficient, high-quality image contour detection
- In IEEE International Conference on Computer Vision
, 2009
"... Image contour detection is fundamental to many image analysis applications, including image segmentation, object recognition and classification. However, highly accurate image contour detection algorithms are also very computationally intensive, which limits their applicability, even for offline bat ..."

implementation on highly parallel, commodity processors from Nvidia, our contour detector provides uncompromised contour accuracy, with an F-metric of 0.70 on the Berkeley Segmentation Dataset. Runtime is reduced from 4 minutes to 1.8 seconds. The efficiency gains we realize enable high-quality image contour
Fast and High-Quality Image Blending on Mobile Phones
"... Abstract-We present a fast and high-quality image stitching approach for creating high-resolution and high-quality panoramic images on mobile devices. In the approach, a sequential panorama stitching procedure is created with color and luminance compensation for reducing differences between source ..."

Implementation Details for “Predictable High-Quality Image Completion”
"... In this supplementary document we provide commented pseudocode for our image completion algorithm. It is more or less a straight-forward implementation of [Wexler et al. 2007] using PatchMatch [Barnes et al. 2009] for fast approximate nearestneighbor search. Refer to Figure 1 for a list and explanat ..."

Super Resolution methods to achieve high quality imaging
"... Now a day the increase in the quality of images is becoming need of the multimedia applications. The quality of the image can be improved by increasing the resolution. There is a limitation for the spatial resolution of an image captured by any present image acquisition device. The increase in the o ..."

of an image. We present an overview of existing SR methods and address the motion estimation and optical blur methods of super resolution to achieve high quality imaging with different optical zoom of low resolution camera. The quality of images is significantly improved and high resolution imaging
High Quality Image Synthesis on Distributed Memory Multiprocessors
"... : The production of realistic images generated by computer requires a huge amount of computation. The use of highly parallel computers allows this process to be performed faster. Distributed memory parallel computers (DMPCs) offer an attractive performance/cost ratio. However, several crucial proble ..."

Fuzzy rendering for high quality image generation
, 1993
"... This thesis is concerned with the field of high-quality image rendering. It describes research into a system for rendering a scene so that the picture produced is accurate to some specified limit. We refer to the system as “Fuzzy Rendering, ” because it deals with ranges of metrics, rather than prec ..."

Comparison of Polarimetric Retinal Nerve Fiber Analyzer Parameters for a Single High Quality Image and the Mean Image from Three High Quality Images
"... Background: To find the correlations and differences between the nerve fiber layer para-meters of a GDx (polarimetric retinal nerve fiber analyzer) in single high quality images and those in the mean image from three high quality images. Methods: The results of scanning laser polarimetry were select ..."

Astola: “DCT Based High Quality Image Compression
- Proceedings of 14th Scandinavian Conference on Image Analysis
, 2005
"... Abstract. DCT based image compression using blocks of size 32x32 is considered. An effective method of bit-plane coding of quantized DCT coefficients is proposed. Parameters of post-filtering for removing of blocking artifacts in decoded images are given. The efficiency of the proposed method for te ..."

for test images compression is analyzed. It is shown that the proposed method is able to provide the quality of decoding images higher than for JPEG2000 by up to 1.9 dB. 1
Optimized Error Diffusion for High Quality Image Display
- Journal of Electronic Imaging
, 1992
"... Displaying natural images on an 8 bit computer monitor requires a substantial reduction of physically distinct colors. Simple minimum mean squared error (MMSE) quantization with 8 levels of red and green and 4 levels of blue yields poor image quality. A powerful means to improve the subjective quali ..."
