[OpenCV] cvResize DL : 0: 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.

[OpenCV] mouse_event DL : 0: This program creates a rectangle when you click the mouse on the window, and stretches the rectangle until you release the mouse. This requires the creation of a mouse callback. For the main function we use a while loop that keeps redrawing each box as its created. Boxes are drawn and windows are created as learned in previous tutorials. The main new thing is the creation of the mouse callback. This is initialized with cvSetMouseCallback. The callback itself is an arbitrarily named function of the form my_mouse_callback( int event, int x, int y, an int flags, void* param) where x and y are the mouse position and event is a code representing what mouse action occured
