Resize



圖像大小變換



void cvResize( const CvArr* src, CvArr* dst, int interpolation=CV_INTER_LINEAR )



src

輸入圖像.

dst

輸出圖像.

interpolation

插值方法:



* CV_INTER_NN - 最近鄰插值,

* CV_INTER_LINEAR - 雙線性插值 (預設使用)

* CV_INTER_AREA - 使用象素關係重採樣。當圖像縮小時候，該方法可以避免波紋出現。當圖像放大時，類似於 CV_INTER_NN 方法..

* CV_INTER_CUBIC - 立方插值.



函數 cvResize 將圖像 src 改變尺寸得到與 dst 同樣大小。若設定 ROI，函數將按常規支持 ROI. -Resize the image size conversion void cvResize (const CvArr* src, CvArr* dst, int interpolation = CV_INTER_LINEAR)　src input image. Dst output image. Interpolation interpolation method:* CV_INTER_NN- nearest neighbor interpolation,* CV_INTER_LINEAR- bilinear interpolation (default use)* CV_INTER_AREA- resampling using pixel relationship. The time when the image reduction, the method avoids ripple appears. When the image is zoomed in, like CV_INTER_NN method ..* CV_INTER_CUBIC- cubic interpolation. Function cvResize change the size of the image src and dst are the same size. If the setting ROI, will be general support functions ROI.
