Through these changes and enhancements, image-based biomarkers will enhance clinical decision making and accelerate the progress that is made through clinical trial research.
Figure 5c shows the final enhancement image; it is obvious that the quality of the enhanced image is improved.

However, the shift-invariance is desirable in many image applications such as image enhancement, image denoising and image fusion.
In particular the fractional-based operators have been used in image quality enhancement, image texture enhancement [13], image denoising [14], and image edge analysis.
Four-chamber delayed-enhancement image shows delayed enhancement of the tricuspid leaflets (curved arrows) consistent with cardiac amyloidosis.
Compared to using multiple images for image enhancement, image enhancement with a single image does not need additional assistant images and has received increasing interests recently.
(b) Four-chamber delayed-enhancement image in another patient shows heterogeneous enhancement of the tricuspid valve mass, consistent with a fibroelastoma.
Due to such advantage, RT is widely used in image analysis, such as watermarking, image enhancement, image de-noising, and texture classification [26, 27].
Figure 2a shows a sequence of corresponding sagittal images of the right breast prior to treatment consisting of (i) a baseline T2 sequence, (ii) a gadolinium enhancement image and (iii) a baseline subtraction image.
CCTVs have many other advantages over optical magnification aids such as: contrast enhancement, image manipulation, reduction of aberrations, less critical focus, more natural working distances, better posture, binocularity and a longer duration of reading [ 6- 8].
