Description: 一种全自动稳健的图像拼接融合算 提出了一种全自动稳健的图像拼接融合算法。此算法采用Harris角检测算子进行特征点提取,使提取的
精度达到了亚像素级,然后以特征点邻域灰度互相关法进行特征点匹配得到了初步的伪匹配集合,并运用稳健的
RANSAC算法将伪匹配点集合划分为内点和外点,在内点域上运用LM优化算法精确地估计出了图像间的点变
换关系,最后采用颜色插值对交接处进行颜色过渡。整个算法自动完成,它对有较大误差或错误的特征点数据迭代
过滤,并用提纯后的数据来做模型估计
-A robust fully automatic image mosaic fusion operator presents a fully automatic image stitching robust fusion algorithm. This algorithm uses the Harris operator angle detection feature point extraction, so that the accuracy of extracting the sub-pixel, and then feature points to the neighborhood gray-scale cross-correlation method for matching feature points have been the initial pseudo-match collection and use of sound RANSAC algorithm pseudo-matching point set is divided into inner and outer points, including point-domain LM optimization algorithm used to estimate accurately the image transform relations between points, and finally the use of color interpolation of the color transition of the junction. The entire algorithm for auto-complete, it has a larger error or error of feature points iterative data filtering, and purification of model data to make estimates

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.

Description: ImageJ是一個基於java的公共的圖像處理軟件，它是由National Institutes of Health開發的。可運行於Microsoft Windows，Mac OS，Mac OS X，Linux，和Sharp Zaurus PDA等多種平台。其基於java的特點， 使得它編寫的程序能以applet等方式分發。
ImageJ能夠顯示，編輯，分析，處理，保存，打印8位，16位，32位的圖片， 支持TIFF, PNG, GIF, JPEG, BMP, DICOM, FITS等多種格式。ImageJ支持圖像棧功能，即在一個窗口里以多線程的形式層疊多個圖像， 并行處理。只要內存允許，ImageJ能打開任意多的圖像進行處理。除了基本的圖像操作， 比如縮放，旋轉， 扭曲， 平滑處理外，ImageJ還能進行圖片的區域和像素統計， 間距，角度計算， 能創建柱狀圖和剖面圖，進行傅里葉變換。
-ImageJ is a java-based image processing software in public, it is by the National Institutes of Health developed. Can run on Microsoft Windows, Mac OS, Mac OS X, Linux, and the Sharp Zaurus PDA and many other platforms. The characteristics of their java-based, making it able to write programs applet, etc. distributed.
ImageJ can display, edit, analyze, process, save and print 8-bit, 16-bit, 32-bit images, support for TIFF, PNG, GIF, JPEG, BMP, DICOM, FITS and many other formats. ImageJ supports image stack functions, namely, a window in the form of multi-threaded Cascading multiple images, parallel processing. As long as memory allows, ImageJ can open any number of images for processing. In addition to the basic image manipulation, such as scaling, rotation, distortion, smoothing things, ImageJ can be a picture of regional and pixel statistics, spacing, angle calculation, can create histograms and profiles, the Fourier transform.
