這個錯誤訊息~是指什麼意思？？有需要改什麼地方嗎？
麻煩各位大大指導一下~謝謝！！

是哪一行發生這個錯誤訊息?

沒寫哪一行錯~
是直接跳出視窗opencv gui error handler~內容寫bad argument(array should be cvmat or ipilimage)in function cvgetsize,c:\user\vp\opencv\cxcore\src\cxarray.cpp(1453)~在這個視窗有中止和重試還有略過三個選項~我按中止之後，就會出現題目所說的錯誤....

是哪一行發生這個錯誤訊息?

它不能呼叫 cvGetSize , 這是 C++Builder 的問題 , 到了 2010 也沒解決 


它在呼叫該函式前會多 push 一個參數上去, 導致函式內部取參數的時候, 取到該值而非 IplImage*
看起來好像是呼叫慣例的問題, 不過我無法確定, 可以確定的是在反組譯除錯視窗下觀察
確實多傳一個參數在 ebp 4 的位置, 如果跳過該指令, 程式可以正常執行
