At a signal-to-noise gain at about 100% we observe only a minor sharpness decrease, as measured by a full-width-half-maximum reduction of 10.5%.
However, in order to enable a good trade-off between bias and variance, i.e., between image sharpness and noise reduction, it is necessary to locally adapt the smoothing parameter h to image features and image noise.
Users select from nine modes including Standard, Dynamic, Nature, Smooth, Nostalgic, Vibrant, Standard B/W, Dynamic B/W and Smooth B/W, with the capability to finely adjust contrast, sharpness, saturation and noise reduction.
They found negligible differences in image quality, noise reduction, and image sharpness between full- and half-time SPECT [22].
The image shows that our algorithm performs well in the reconstruction by keeping image sharpness while allowing high-quality noise reduction.
It conserves image sharpness and details while reducing speckle noise.
Turn off noise reduction if it affects the sharpness of your pictures.
The cheese is tart and creamy; the other ingredients -- arugula, escarole, pear compote and balsamic vinegar reduction -- contribute notes of sweetness, sharpness and fruit.
In mammography compression is essential for various reasons: (1) scatter reduction; (2) dose reduction (3) improved image sharpness; (4) to maintain a uniform film density; and (5) to improve the separation of the breast tissue structures.
