6^F推yyc1217:嗯…影像就是連續的播放圖片而成的東西02/08 21:14

7^F→yyc1217:所以如果你要處理每一張圖片就是在CaptureCallback裡處理02/08 21:14

8^F→yyc1217:framel代表的就是每一張圖片02/08 21:15

9^F→yyc1217:建議你把CaptureCallback裡的程式碼先註解掉試看看02/08 21:15

10^F→yyc1217:然後傳進來的圖像是以三原色作儲存並且是BGR的順序02/08 21:16

11^F→yyc1217:故函式裡的程式碼代表的是將每20行第i*j個像素變成紅色02/08 21:17

12^F→yyc1217:所以理論上你所謂的紅色直線應該不只一條，並且是橫向的02/08 21:18

13^F推yyc1217:記住處理一個影片 = 處理很多張圖片02/08 21:21

16^F推yyc1217:你只有下一個可以跑就用下一個呀= =02/09 00:36

17^F→yyc1217:重點都在於你要如何處理IplImage 要用顏色或形狀或其他02/09 00:37

18^F→yyc1217:也就是在一張圖裡找出指尖的位置這就看你個人的想法了~02/09 00:43

5^F推yyc1217:用ROI把影像中你有興趣的地方框下來再直接做處理02/05 00:44

6^F→yyc1217:就不用創新圖了~02/05 00:44

[問題] OpenCV 調整Webcam解析度 640*480

1^F推yyc1217:希望這對您有幫助http://tinyurl.com/yaw498y01/25 03:37

2^F→yyc1217:之前1.0版時有些功能沒有實作現在2.0版不知道有沒有01/25 03:38

3^F→yyc1217:但據我的經驗解析度通常與電腦或camera的設定有關01/25 03:39

4^F→yyc1217:OpenCV好像預設是沒有管這個的...01/25 03:40

6^F→yyc1217:你可能到驅動程式的相關設定看一下試試看~01/25 03:40

7^F推yyc1217:耶...影像大小不是解析度吧= =01/25 03:42

8^F→yyc1217:也有可能640*480的結果是用320*240放大兩倍來呈現的01/25 03:45

1^F推yyc1217:capture的宣告做一次就好故要放在迴圈外01/24 21:33

2^F→yyc1217:只有從capture抓image及後面部分才要在迴圈內01/24 21:34

3^F→yyc1217:參考http://tinyurl.com/yezz75v 這裡有很多教學01/24 21:34

[問題] 請問opencv有哪一版可以完全相容於windows7

9^F推yyc1217:不知道你是不是要把全排列的結果都存入陣列？12/28 11:10

10^F→yyc1217:這樣的話應該會有32種或31種才對12/28 11:10

12^F→yyc1217:如果是這樣的話，就把1~32轉成二進位後的結果存入即可12/28 11:11
