我目前正在尝试对存储在图库文件夹中的图像运行一些opencv过滤器(即找到egde，Median等)。

但是加载图像时出现错误。我的设备是带有Android 3.2的galaxy标签10.1，我的opencv-API级别8。

我在Button上有以下来源:

  @Override
    public void onClick(View v) {

      Bitmap myBitmap = BitmapFactory.decodeFile("/sdcard/image1.jpg");                 
      Bitmap myBitmap32 = myBitmap.copy(Bitmap.Config.ARGB_8888, true);
      Mat pic1 = Utils.bitmapToMat(myBitmap32);

    }

最佳答案

openCV库未附加到您的应用程序。请执行以下操作(我假设openCV库已导入到您的工作空间中)。在程序包资源管理器上>右键单击应用程序项目>属性>在库下单击添加>选择openCV确保在Java Build Path上没有与openCV相关的任何内容
