I have a python script in the same folder as a video I want to convert to a numpy array. My video is called 'test.mp4'.
Within my script, I want to call someFunction('test.mp4') and get back a numpy array. The resulting numpy array should be a numpy array of images, where each image is a 3-d numpy array.
Does that make sense?
Thanks!

Using OpenCV Library imread() function is used to load the image and It also reads the given image (PIL image) in the NumPy array format. Then we need to convert the image color from BGR to RGB. imwrite() is used to save the image in the file.
Convert a list to a NumPy array: numpy. You can convert a list to a NumPy array by passing a list to numpy. array() . The data type dtype of generated numpy. ndarray is automatically determined from the original list but can also be specified with the dtype parameter.
The array object in NumPy is called ndarray . We can create a NumPy ndarray object by using the array() function.
Converting an image to an array is an important task to train a machine learning model based on the features of an image. We mainly use the NumPy library in Python to work with arrays so we can also use it to convert images to an array. Other than NumPy, we can also use the Keras library in Python for the same task.
skvideo is a python package can be used to read video and stores into the multi-dimensional array.
import skvideo.io videodata = skvideo.io.vread("video_file_name") print(videodata.shape) For more details: http://www.scikit-video.org/stable/index.html and http://mllearners.blogspot.in/2018/01/scikit-video-skvideo-tutorial-for.html
