OpenCV Mat 也可以转化为 SKImage。或借助 SKData 而非 SKPixmap 来指定像素数据。(SKImage 和 SKData 的用法详见 番外 #1 。)当然,也没有什么阻止我们使用或指定其他外部内存资源作为像素数据。 internalstaticpartialclassOpenCvSharpExtenstions{publicstaticboolIsCompatibleTo(thisOpenCvSharp.MatTypecvType,SkiaSharp.SK...
在OpenCvSharp中,Mat对象是一个用于存储图像或矩阵数据的类。它包含图像的宽度、高度、通道数、数据类型等信息,以及实际的图像数据。 3. 编写C#代码,从OpenCvSharp的Mat对象中提取图像数据 要从Mat对象中提取图像数据,可以使用Mat.ToArray<T>()方法,其中T是数据类型(例如byte、ushort等)。对于8位无符号整数...
