	)

Show the visualized results for classification models.

Parameters

[in]	im	the input image data, comes from cv::imread(), is a 3-D array with layout HWC, BGR format
[in]	result	the result produced by model
[in]	top_k	the length of return values, e.g., if topk==2, the result will include the 2 most possible class label for input image.
