How to get the Numpy array of file stream of any image












0















I'm trying to use the imageai python library, and more particularly this function:



detector.detectObjectsFromImage()


The doc says it should be used with a Numpy array of file stream of any image.



https://imageai.readthedocs.io/en/latest/detection/index.html



When I pass it a Numpy array, like this:



detections = detector.detectObjectsFromImage(input_image=anumpyarray,input_type = "array")


I get the error:




detections =
detector.detectObjectsFromImage(input_image=anumpyarray,input_type =
"array") File
"/usr/local/lib/python3.6/site-packages/imageai/Detection/init.py",
line 517, in detectObjectsFromImage raise ValueError("Ensure you
specified correct input image, input type, output type and/or output
image path ") ValueError: Ensure you specified correct input image,
input type, output type and/or output image path




Is it because a Numpy array and a Numpy array of a stream of an image are different things?

  • One thing to note is, if you re-read the documentation for that function, you don't have to pass it a Numpy array, it's just possible. You can also just pass it the path of an image.

  • Sure, but I'm analyzing a video through an iterator which gives me numpy file. I would be too costly to save each image just to pass it to the function. That's why I want to pass it directly as a numpy array
