应用differentFilter时出现错误 [英] i have an error when applying differenceFilter

问题描述

我有此代码

i have this code

class Program
    {
        private GrayscaleBT709 grayscaleFilter = new GrayscaleBT709();
        private Difference differenceFilter = new Difference();
        private Threshold thresholdFilter = new Threshold(70);
        private Opening openingfilter = new Opening();
        public Program()
        {
            Bitmap image = new Bitmap("d:\\m.bmp");
            Bitmap backgroundFrame = new Bitmap("d:\\bc.bmp");
            grayscaleFilter.Apply(backgroundFrame);
            Bitmap currentFrame = grayscaleFilter.Apply(image);
            differenceFilter.OverlayImage = backgroundFrame;

               Bitmap motionObjectsImage = differenceFilter.Apply(currentFrame);


           }
}

这段代码给我一个错误，是:
源图像和重叠图像必须具有相同的像素格式.
我该如何解决此错误?

this code give me an error that is :
source and overlay images must have same pixel format.
how can i solve this error?

推荐答案

您需要转换一张图像，以使两个图像具有相同的像素格式.您可以在此处查看转换功能:

您可能需要稍作调整.

You need to convert one of the images so that both images have the same pixel format. You can have a look to a conversion function there:

You will probably need to adapt it a little bit.
