Description: 你可能会认为生成一个带柔和阴影的特效文字与生成一个带光圈的特效文字是完全不同的，其实他们所用到的技术是完全相同的，只是在设置上有些许变化。 在带柔和阴影的效果中，我用到了GDI+中的一些插值模式来生成模糊的文字轮廓，当位图绘制平面放大时，插值模式决定原来某点像素应该怎样和周围的融合。 低质量的插值只是简单的把一个像素变换成同色色块，高质量插值如高质量双线性插值与高质量双三次插值会考虑像素色的平滑与反走样，我发现高质量双线 性插值模式最好。-you may think that a generation with a soft shadow effects of the letter and generate an aperture with the magic words are completely different, they actually have to use the technology is identical, the only set slightly changes. With soft shadows in effect, I used the GDI some of the interpolation model to generate fuzzy outline of the text, when the Bitmap Rendering Large Plane, interpolation mode decision of a point of what should pixels and around integration. Low-quality interpolation just simply put a pixel transform into the same color against a high-quality interpolation such as high-quality and high-quality bilinear interpolation bicubic interpolation will consider pixel color with a smooth anti-aliasing, I found quality bilinear interpolation mode best.

Description: 兴趣区域选取，扩展兴趣区选取的功能，不必局限于圆形或方形轮廓落形态-Most ROI Drawing Tools limit you to either drawing a circular ROI or a rectangular ROI perpendicular to the X-Y axis. ROI Draw s primary purpose is to expand upon the drawing of rectangular ROI s by allowing you to draw them at any angle.
After selection of an ROI, ROI Draw crops and rotates your ROI into the X-Y plane using a bicubic interpolation algorithm (chosen in order to preserve textural properties) so that spatial statistics may be analyzed.
ROI Draw outputs a .MAT file which, in addition to storing your rotated ROI, stores the original image and a mask file (for calculating pixel statistics), and the coordinates of the corners of your ROI so that they can be used to colocalize an ROI on another image.
ROI Draw at this point only works for DICOM images as its primary purpose is for application in medical research. Platform: |

Description: In mathematics, bicubic interpolation is an extension of cubic interpolation for interpolating data points on a two dimensional regular grid. The interpolated surface is smoother than corresponding surfaces obtained by bilinear interpolation or nearest-neighbor interpolation. Bicubic interpolation can be accomplished using either Lagrange polynomials, cubic splines, or cubic convolution algorithm.
In image processing, bicubic interpolation is often chosen over bilinear interpolation or nearest neighbor in image resampling, when speed is not an issue. In contrast to bilinear interpolation, which only takes 4 pixels (2×2) into account, bicubic interpolation considers 16 pixels (4×4). Images resampled with bicubic interpolation are smoother and have fewer interpolation artifacts.
Suppose the function values f and the derivatives f_x, f_y and f_{xy} are known at the four corners (0,0), (1,0), (0,1), and (1,1) of the unit square. The interpolated surface can then be written Platform: |
