How to implicitly convert type 'Emgu.CV.Structure.MCvObjectDetection[]' to 'System.Drawing.Rectangle[]'?

问题

I got that code from emgu's site, I fixed some bugs, but there is 2 more, which I can understand:

Rectangle[] regions;
regions = des.DetectMultiScale(gpuBgra);

Cannot implicitly convert type 'Emgu.CV.Structure.MCvObjectDetection[]' to 'System.Drawing.Rectangle[]'

How do I solve the problem?

回答1:

You can try this:

MCvObjectDetection[] results = hog.DetectMultiScale(gpuBgra);
Rectangle[] regions = new Rectangle[results.Length];
for (int i = 0; i < results.Length; i++)
    regions[i] = results[i].Rect;

First, get the results as MCvObjectDetection[], then transform it into Rectangle[].
