Those operations are executed with respect to all unsharp masks involved in the original image. Since the one processor system (100) shares the unsharp masking operations with the other processor system (200), the total operational speed is increased approximately twice as much as an image ...
In an unsharp masking processing for sharpening images such as radiographic images, an emphasizing coefficient of an image and parameters for real-time change of picture quality are set interactively. The entire image is divided into a plurality of regional images and filtering optimized for each pix...
Explore unsharp masking in Adobe Photoshop, and learn how to make images more clear and dramatic by increasing contrast and reducing noise.
unsharp masking Also found in: Acronyms, Encyclopedia, Wikipedia. un·sharp mask·ing in radiography, superimposing a blurred negative of a radiograph to cancel large density differences, leaving fine detail more visible. Farlex Partner Medical Dictionary © Farlex 2012 Want to thank TFD for its...
In view of the low computational efficiency and the limitations of the platform of the unsharp masking image enhancement algorithm, an unsharp masking image enhancement parallel algorithm based on Open Computing Language (OpenCL) is proposed. Based on the analysis of the parallel characteristics of th...
Unsharp masking filter based shadow-invariant feature extraction for hyperspectral signatures 来自 学术范 喜欢 0 阅读量: 99 作者:U Sakarya,C Demirkesen,M Teke 摘要: Hyperspectral image processing is an important research topic in remote sensing. The effect of atmosphere, especially cloud shadows need...
image is a combination of the resolution of fine details in the image, the apparent size of those details as seen by the viewer, and the edge contrast (called accutance) in the image. Unsharp mask only addresses edge contrast. Even so it can be quite effective, and is simple and fast....
