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: |
