使用 Caffe、OpenCV 和 C# 的 CNN 分割

如何解决使用 Caffe、OpenCV 和 C# 的 CNN 分割

我有一个 C# 项目需要使用图像分割。我主要从 pyimagesearch.com 学习了 DNN 和 OpenCV（感谢 Adrian！很棒的网站！）但是，我不明白我应该如何从结果中提取单个片段。下面是python中的部分代码：

ORDER BY

我能够创建网络，加载 .caffemodel，创建 blob 并运行“forward()”但我不知道如何编写等效的

blob = cv2.dnn.blobFromImage(frame,1 / 255.0,(1024,512),swapRB=True,crop=False)
net.setInput(blob)
start = time.time()
output = net.forward()
end = time.time()
# infer the total number of classes along with the spatial
# dimensions of the mask image via the shape of the output array
(numClasses,height,width) = output.shape[1:4]
# our output class ID map will be num_classes x height x width in
# size,so we take the argmax to find the class label with the
# largest probability for each and every (x,y)-coordinate in the
# image
classMap = np.argmax(output[0],axis=0)
# given the class ID map,we can map each of the class IDs to its
# corresponding color
mask = COLORS[classMap]
# resize the mask such that its dimensions match the original size
# of the input frame
mask = cv2.resize(mask,(frame.shape[1],frame.shape[0]),interpolation=cv2.INTER_NEAREST)
# perform a weighted combination of the input frame with the mask
# to form an output visualization
output = ((0.3 * frame) + (0.7 * mask)).astype("uint8")

在 C# 中（我在 OpenCV 中使用 EMGU 包装器）

这是我的代码：

(numClasses,width) = output.shape[1:4]
classMap = np.argmax(output[0],axis=0)
mask = COLORS[classMap]

它只显示宽的黑色矩形。在此先感谢您的帮助。
