自畫像

這是用了新設備，感覺好有趣，DEV C++原本我們還停留在小黑框，上了今天的課，才發現原來有這麼多功能，原來他可以跟視訊設備做連結，讓我們覺得真新奇。

下面這些是新學得的東西，為每個顏色圖片設定空間。

//為圖像申請空間

pImg2 = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 3);

gray = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 1);

bw = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 1);

pCannyImg = cvCreateImage(cvGetSize(pImg), IPL_DEPTH_8U, 1);

//cvCvtColor彩色轉灰階

cvCvtColor(pImg, gray, CV_BGR2GRAY);

//cvThreshold灰階轉黑白

cvThreshold( gray, bw, 63, 255, CV_THRESH_BINARY );

cvThreshold( pImg, pImg2, 127, 255, CV_THRESH_BINARY );

今天作業是WebCam然後製作效果，

感覺滿好玩的!!!!!

原來網路上那些效果其實沒有那麼難嘛~~~
