怎么運行/opencv/modules/imgproc/test下的test_cvtyuv.cpp

要運行test_cvtyuv.cpp，你需要按照以下步驟操作：

  1. 獲取OpenCV源代碼，編譯并安裝opencv：首先，確保你已經下載并安裝了OpenCV。如果沒有，請前往OpenCV官方網站下載源代碼。安裝參考連接：https://blog.csdn.net/shizuguilai/article/details/136406722

  2. 運行測試：在構建build目錄中，你可以運行測試程序。使用以下命令：

    ./bin/opencv_test_imgproc --gtest_filter=cvtyuv.*
# 或者是下面這樣？
./bin/opencv_test_imgproc --gtest_filter=*ColorYUV* # 運行特定的顏色轉換測試
# 或者試試下面這個？注意！下面是gtestp不是gtest
./bin/opencv_test_imgproc --gtestp_filter=Imgproc_ColorYUV.accuracy

    這將運行與cvtyuv相關的所有測試用例。因為test_cvtyuv.cpp本身并不包含主函數（main），因為它是設計來被 OpenCV 的測試框架自動發現和執行的。測試框架（基于 Google Test）會自動識別 TEST_P 宏定義的測試用例并執行它們。

請注意，確保你的構建環境已經正確設置，以便能夠編譯和運行OpenCV。如果你遇到問題，可以查看OpenCV官方文檔或在社區尋求幫助。

祝你好運！🚀
