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: ：采用双三次插值实现图像放大具有较高的图像质量，但运算量很大。在分析常用插值算法的基础上，提出一种基于区域的双三次 插值算法。该算法避免进行图像分割，通过被插值点四邻域像素的均值来划分图像的平坦区域和纹理细节复杂区域，采用不同的插值算法 进行计算。实验结果表明，与传统的双三次插值算法相比，该算法在保持放大后图像质量的同时，运算量降低 10 以上，具有一定的实用 价值。 -】Bicubic interpolation is an effective way to get well-qualified high-resolution image, but with high calculation load. The common used interpolation methods are discussed. A new region-based bicubic interpolation is proposed. Without segmenting the image, the mean value of the four neighboring points of the interpolated point is calculated which is used to divide the image into two regions: the flat region and the complex region with more details. Two different interpolating algorithms are chosen for each region. Experimental results show that the proposed algorithm can keep the image quality equal to the original algorithm while reducing the calculation load more than 10 percents. It is useful for applications. 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: |
